Resideo Reviews

We finished building out house about a year and a half ago and put in 4 of these thermostats. From the get-go, Resideo had difficulty recognizing the divides, syncing with them, and staying synced. After a few months of continual babysitting it seemed to straighten itself out for a while (merciful, considering it was wintertime). We shut them off for the season and have not been able to get them working again this year. I’ve reset our router, run the repair protocol through the thermostats themselves, factory reset the thermostats, deleted and redownloaded Resideo ...all to no avail and each step creates a new sticking point. Sometimes it can’t find a network, sometimes it goes all of the way through setup and then errors out at the very end, and now it won’t even begin setup because Resideo shows the connection to my thermostat but won’t ever proceed to the next screen when it’s tapped (it just highlights gray for a second, signifying it recognizes the tough, but does nothing). It’s highly disappointing to spend so much money on brand new state of the art thermostats and have them fail repeatedly due to poor programming on Resideo side, and to have no way to set them up and use them without this hateful app.

My thermostat decided to go offline at nine this evening. I live in Alaska. It’s currently zero degrees Fahrenheit outside and getting colder. This literally happened apropos of nothing. We’ve had the thermostat for years with no issues. I tried to reset the Wi-Fi on the thermostat and suddenly, my app is telling me to connect to a network beginning with a T, while my thermostat is telling me to connect to a network beginning with an F. I find the network displayed on my thermostat and am able to connect, but Resideo won’t connect. This thing keeps shutting my furnace off. I’ve given up trying to reconnect the thermostat-I’ve tried factory reset, deleting thermostat from my app and setting it up as a new one….nothing. I can’t even get this thing to stop telling my furnace to shut off! Which means I am unable to keep the heat on manually. And again, I’d like to reiterate here THAT I LIVE IN ALASKA. We may not be “off the grid”, but it’s certainly starting to feel like I live in an igloo. Customer support isn’t available for another ten hours, and there are no stores open within hundreds of miles so I can’t even run out and buy another cheap thermostat just to get the heat working. I’m beyond furious.

I’ve had a Honeywell thermostat for three years, and until this week I’ve suffered through MULTIPLE issues that arise CONSTANTLY. If you’re looking for a WiFi thermostat stay as far away from Honeywell as possible. Customer service hours are very limited, which when you’re thermostat is out at 3AM, for the third time this month and it’s 18 degreees out, know that there will be no one to help you, period. But also know that you’ll regularly lose the connection between app and thermostat, and you have to set it up again as if it’s a new thermostat, which takes close to 10 minutes, and sometimes it won’t connect without reaching out to customer service and getting help with a hard reset. I can’t tell you all what a mess this thermostat, app, and company customer service is in a reasonable amount of time, but I can say I have another house with a competitor thermostat and in the three years I’ve also had that one I’ve NEVER had one issue! My Honeywell has issues on a monthly basis. BUYER BEWARE!!!!!!!
UPDATE: Resideo will now just not work. I have been using it with continued random issues, but now when Resideo opens it just gets stuck on the page with the Honeywell opening screen (hallway table and backpack with the name) and won’t do anything, deleting and reinstalling doesn’t help. I’ve literally never come across such a bad performing app and system.

TL;DR: Keep the old app, Total Connect. Too much of a delay; massive headache.

iPhone 13 Pro: Compared to the Total Connect app, this is a huge downgrade. Weather takes forever to update on the main page but my biggest gripe with Resideo is that it is VERY slow to update and respond to thermostat changes. For example, when I open Resideo , it will be stuck on the last known settings (mode, temp, etc) - even if the settings are outdated (e.g., I changed the temp on the screen since I last used Resideo or someone else changed them on Resideo ). If I change the settings at that point and then close Resideo , no changes will be registered (even thought Resideo temporarily reflects the change). Instead, I have to open Resideo , click into one of the thermostats, go back to home, minimize Resideo and continuously navigate back to Resideo until I see the settings update. At that point I can finally make a change and it's a >50% chance that the change will successfully apply. It's a guessing game if I don't know what the current settings are. Instead, I went back to the TC app which updates immediately and shows the settings in real time. Hopefully, they don't fully retire the TC app. Otherwise, there are plenty of other smart home devices to choose from.

This thermostat was installed when we bought a new a/c about 3 months ago. On the colder nights we normally turn our heater on so that if the house temp drops to 75 or below the heater kicks on to maintain the 75 degree setting. EVERY time my husband or I do this we wake up in the middle of the night sweating!! The temperature turns up to 83!!! EVERY SINGLE TIME! The manual is useless unless you speak robot. My husband called the a/c company who installed it and they told him some directions on how to fix it, which didnt work because we couldn’t even find the buttons they told us to push on the thermostat. I downloaded Resideo thinking in may shed some light on the problem I am having. So I register my account, confirm my email. Resideo wants me to register my device by pushing the temperature on the middle of my thermostat screen for 5 seconds!! Of course this didn’t work because the thermostat is not a touch screen. I felt like a complete dolt for standing in front of the thermostat touching a screen over and over that literally did nothing.
It was like touching a computer screen from the 90’s and expecting it to actually respond!! So frustrated!!! All I want is for my children to be warm in their beds at night and Honeywell sure can’t seem to make this happen. Very frustrated!!!

Resideo is fine, when it actually works. However, it is constantly disconnecting from the WiFi (multiple times a day). It only seems to remain connected to the WiFi when my phone is connected to the same WiFi. Now imagine if you have an upstairs and downstairs thermostat, with corresponding WiFi’s. Even if you try to access the system from home, one of them will always show as offline because you can’t be on two WiFi’s at once. Do I need to get into accessing it remotely, if I can’t even access it from home??

In addition, it has so many bugs. I will go in and change a temperature setting and Resideo reverts right back to where it was. For example: My thermostat is off, I will go in and turn the heat on via Resideo . The screen will allow me to change it and then seconds later, reverse it back to off, as if I never turned it on. Lastly, it will sometimes completely drop one or both of the thermostats from Resideo .

The whole point of Resideo was the be able to control the thermostat remotely. If I have to be at home on the WiFi to access it, there’s no point. If I have to go directly to the thermostat to update it because Resideo is undoing my selections, again there is no point to this. It feels like such a waste of time and money. I regret this purchase.

Resideo is visually appealing and logically organized, but there is a major flaw. When returning to Resideo , it doesn’t reflect current settings of the thermostat unless Resideo is terminated and then relaunched.

For example: yesterday I changed the set temperature from 70 to 72 in the morning and when submitted, Resideo showed a set temperature of 72 and Hold until 3:45 PM. This is all correct. When I went back into Resideo today, instead of showing a set temperature of 70 and FOLLOWING SCHEDULE is still shows a set temperature of 72 and Hold until 3:45 PM. I can leave Resideo open and this will not change; there is no obvious way to force Resideo to refresh what is shown. If I terminate Resideo and then launch it again, it correctly shows a set temperature of 70 and FOLLOWING SCHEDULE

I like Resideo but I cannot recommend it because of this behavior. When Resideo is already running and the user switches back to it, before presenting information to the user, it should always refresh the data since someone else may have changed the thermostat via local controls, someone else may have changed the settings via another instance of Resideo , or the previous app setting changes may be modified by a schedule, as in my example.

They have updated Resideo recently, maybe the 2nd to the last update basically messed Resideo up. Like what the others are experiencing, the scheduling function has been a nightmare since. I used to be able to change it and it will follow the schedule properly (or even if I leave the schedule alone). Now, the schedule won’t change until you go to Resideo and close it, open it again and maybe if you are lucky it will show “following schedule”, otherwise, you have to close and reopen Resideo several times. It is always showing “no schedule”. Also, before when I click and adjust the temp, it will give me an option to either hold for a period of time, hold temporarily or remove hold, now it does not do that all the time, sometimes I click out of the main page where you adjust the temp and go back and it will show up, most of the time I have to close Resideo out a few times to be able to get these options to show up. Also, I did not change any of the settings in Resideo nor the thermostats and the only thing that I change constantly is the temp and schedule which I used to do all the time and Resideo always follows the schedule. Obviously something got messed up on the updates, I wish they leave Resideo alone, I understand that it is necessary for security purposes but sometimes if it ain’t broke don’t fix it. Do not need the bells and whistles, just app the works because it used to. Please fix the bugs soon, its a great app when it actually works.

I came from a pre-Google Nest and chose Honeywell because of the large variety of thermostats to meet my various needs. Resideo was clean and simple, but after using it for almost two years, I’ve realized it’s too simple and their support doesn’t care. Resideo lately has gotten very slow. It takes a minute or two for Resideo to display the current temperatures or settings of my thermostats. Nest let you set a schedule but override that with geolocation. Nest also ran the fan for a forced-air system for several minutes after the burners or compressor turned off to push that bonus heat or cooling around, saving additional money. Honeywell has neither feature. When I’ve asked about why I can’t have both geolocation and a schedule for my thermostats, I’m told “you currently can only have one or the other” with no explanation why or timeframe for it to get added. In fact, it doesn’t sound like they have any plan at all to implement these features. Honeywell Home is not actually Honeywell anymore, but was spun off to this app. Maybe this app doesn’t have the resources to properly support Resideo or the motivation to care, but now I’m stuck with a worse and worse app that hasn’t added features in…ever? and support that doesn’t want to actually listen to its customers.

I’ve had a Honeywell Lyric thermostat for a few years now and up until recently, the interface between Resideo and thermostat worked like a charm. Recently however, (since they changed to the Honeywell home app) the geofence has been sporadic at best. When I get home after 9 hours away at work to find that the thermostat never turned down and my house has been toasty warm all day, it is beyond frustrating. If it only happened once or twice I would have an issue with it, but it has occurred many times now. I tried contacting tech support (because they were extremely helpful when I purchased the thermostat) only to be left waiting for a rep for over an hour with no response (three times now). I also tried chatting with a tech support rep with a similar hour plus wait with no response. My final attempt at emailing tech support was responded to after about a week (despite the fact that their web site says they will respond within 48 hours). Unfortunate the email response did not provide a solution so I responded to the email with additional information. That was over a week ago and I have still not received a response. I would have highly recommended the Honeywell Lyric and app in the past. However, after this experience I would recommend another brand with more stable service and more responsive tech support.

Shopping for the perfect thermostat for your home leaves a lot of options these days. Smart thermostats have become the standard, but they’re often only as good as their companion apps. We recently installed a completely new heating and cooling system, controlled by a feature-rich Honewell t10 thermostat. The thermostat has several great features which allow us to have total control over our system, but Resideo ’s bugginess makes the whole ecosystem feel clunky and unpolished. While I’m sure the developers meant well, many of the core functions don’t work well in Resideo , leading to forced restarts just to check in on the temperature of the home while I’m at the office. Resideo should refresh upon open, displaying the proper temperature inside and out, and the proper settings, as well as confirming whether the geofencing feature is working properly. However, it just doesn’t work. Many times when opening Resideo , it’ll display information from hours prior, and the only way to get accurate, real-time information is to force close Resideo then reopen it. A companion app for a feature-rich thermostat should just work better. If you’re reading this and considering adding a smart thermostat to your home, do some research on their companion apps. While Nest isn’t much better, at least the information you’re seeing on your screen is, well, up to date and accurate.

I’ve had this for probably six months now. My only complaint is that sometimes it doesn’t recognize that my wife is home. I set it to give me an alert and I keep having to turn the geofencing feature off until I get home. Aside from that quirk it is terrific.

Second complaint is data logging, or the lack thereof. It’s not a comfort issue or anything like that but I find it amazing that there’s no way to see how many hours it’s operated or in what mode and what the temperature was say every hour for at least a day or a week. At one point I set the modes too close and believe that it would heat up the house then turn on the A/C to cool it back down. With a data log feature I’d have seen that sooner.

My wife is disabled and we don’t leave the house at regular times each day so the competition’s device that “learns” your schedule was of no use to us. In theory this is a much better option however Honeywell needs to build in a data logger and definitely needs to fix the Geofencing reliability. At the very least give us a button to override the home/away and/or refreshing the search when we know for a fact that someone is home.

The thermostat itself is pretty good. I don’t have any complaints. Resideo ? Well, that’s a whole different story. The constant alerts and notifications are as annoying as a toddler who is bored. They both are incessantly begging for your attention for no good reason. Why does the geofencing glitch out? Who knows! Why does the connection fail multiple times a week (and sometimes per day)? Who knows! The good news is I can just ignore the alerts and it usually resolves. However, my T5 device disappeared from my app device list. I have been through the “add new device” setup about 10 times and it gets right to the end where you answer some questions about your heating/cooling and then gives an error about being unable to complete set up or something equally non-explanatory.

Resideo worked for a good long time with just the annoying notifications being the issue. Now Resideo refuses to let me add my thermostat. So...you be the judge. If you want a nice touch screen thermostat, you’ve got it. Besides that, there I absolutely no guarantee it will be “smart” because Resideo has become useless. Sigh. Who has the time for this? Not me.

Resideo was very fluid for our thermostats and with the introduction of runtime I think it was the perfect way to express a full look of heating and cooling over a period of time without having to wait for that email that was on the 20th of the month. If there could be a developer that would look into creating a way to incorporate into Resideo specific runtime based by the hour, it would make the “day” look of runtime a lot more detailed than just a solid bar indicating the total heating/cooling of that day. I feel the need of having that specific data will help with creating schedules for folks who want to save energy, letting them know the time of day that the most heating/cooling is done and letting them know ways they can decrease the amount of energy being consumed by lowering the temperature during those hours. There is so much potential having hourly data for runtime and I really look forward to it being incorporated into the runtime section of Resideo in the near future if it could be done.

First, Resideo works. I can control my thermostat from anywhere in the world (assuming my wifi works, but that’s a different review).
However, there are really two things I don’t like about it. The two main advantages of Resideo should be maintaining my programmed ‘stat while away and quick reads in the middle of the night (I got chilly last night and wanted to know what the temp was in the house). Well, the programming feature is buried somewhere. I’d rather have it on the main page. Maybe it’s because I only have one thermostat to control that I’m annoyed by this. If I had more than one I’d want to know which one I was controlling so I can give the benefit of the doubt here. The biggest problem is that I wear reading glasses and have to fumble for them if I want to read the house temp in the middle of the night. Make everything bigger and more obvious. When you wake up at 2am cold and need to know these details, it shouldn’t require reading glasses and focus energy. The digits are too small even with my cheaters (and my eyes aren’t THAT bad, just bad enough).

By sheer coincidence I woke up and noticed a visual water leak badge alert on my phone. I never heard an audible alert from my phone. Went to the detector and heard the alarm on the detector itself (all was dry though, so either this is extremely sensitive or it was a false alarm). I then checked Resideo settings thinking maybe I’d muted something accidentally during set up, but this was not the case— I found no way to adjust or specify the alert types. In my view my phone should be blaring a loud alarm when a leak is detected. It’s an emergency, right? A badge alert does no good whatsoever, and if there was an audible alert, it was too short and didn’t even arouse me from sleep. This is very concerning, because if I hadn’t woken up by coincidence myself and happened to 1) check my phone and 2) notice the tiny little badge notification on my phone, there could have been thousands and thousands of dollars worth of damage taking place and I’d have no knowledge, being I was out of earshot of the alarm on the detector itself. Everything else has seemed to functions well and reliably, so this has shaken my confidence in the device.

Go to create account. Can’t. End up calling tech support which is not accessible in app without sign in. They confirm it’s app error not allowing account creation. They make one for me. Go to set up water leak detector. Takes full app reboot twice in order to finally get WiFi to finish connecting on device. Then the device itself says it’s 20 degrees warmer than it is in room per other thermo device in room as test and humidity reads 20% lower. This is initial reading. Maybe it will update more accurately in a bit. But I go to update alert settings.... and it’s so buggy that when I go to back out of alert settings it gives me an alert that it may take 24 HOURS to change how I get alerts from the device... AND then I get stuck in a loop where it just reloads the same settings page after each time I try to back out of the settings and it gives me this alert... requiring yet another full app reboot... off to a bad start Honeywell... will give your product longer than a few hours to redeem itself. But, so far an underwhelming initial user experience.

Typically, we have zero issues with Resideo or our thermostat. Lately, it has been quite frustrating. The geofencing feature has a mind of its own and seems to work when it wants. Resideo stopped recognizing our thermostat resulting in me having to set it up again. Not a big deal, right? Well, I spent 30-40 minutes standing in front of the thermostat going through the setup process in Resideo a good 10 times. System still doesn’t work and Resideo shows I have no devices setup. I eventually gave up and will try another time. Extremely frustrating. I got to the end of the process several times and was prompted to configure the device and then register it (which I have already in the past). It would think for about 3 minutes and eventually give me an error message. Then would say setup incomplete and prompt me to start over...

Honeywell, never had issues before. What’s going on and how can I make this function properly again? This is the second smart thermostat I have had made by Honeywell. First one melted and almost caught fire... thank you

Resideo looks pretty good and setup was easy. Programming a schedule is a bit fidgety, but I don’t need to change it often so that’s fine. After that it runs the schedule and everything operates the way it should.

Update: The issue below was bothering me for months, but customer support had me delete and reinstall Resideo and that seems to have fixed it!

Original issue: The one big issue is that when I open Resideo it takes about 30 seconds to update to the current status of my T9 thermostat. Every once in a while it updates in just a couple seconds but usually it is slow. During that time, I have to keep Resideo open and just wait. If I switch to a different app and come back later it does not update in the background. If I quit Resideo completely and relaunch I still have to wait. So it does work, but it’s quite annoying when all I want to do is a quick status check or bump the temp up or down. I have a long delay where I just stare at out-of-date info and can’t use my phone.

I have had my system for two years now. This month trouble trouble trouble. I’ve had trouble last year with the thermostat on the wall go blank but the installer Royal Air said they fixed it. Now the thermostat has gone blank three times this past week and dead today. So I updated Resideo . No help there.

My last system in the same house worked great for 10 years in a house I bought brand new. I just thought it would be time to upgrade to a two speed system, Carrier. My wife is completely disappointed we got a new system. She freezes in the winter and I sweat now this summer. Why would the thermostat go blank???? This is high tech??? I would rather have the old mercury bubble thermostat and no other interference. We have not advanced anything by going wireless. We have gone backwards. Thank God no one has tried to reinvent the wheel by making it run on WiFi and logic language!!!! Someone will try! 👎🏻👎🏻👎🏻👎🏻👎🏻

I am using the Lyric thermostat, and while I love the features like geofencing, and it does a great job handling the aspects of managing my AC/heating, the connecting to WiFi and configuring the thermostat is horrible! It is something that should take 5 minutes or less, but instead it has taken me over half an hour waiting mainly for Resideo to communicate with the thermostat, which the thermostat times out and I need to restart the process by force quitting Resideo , and relaunch, re-navigate to the WiFi settings on the thermostat, and start the never loading process about 3 more times until it finally shows my WiFi and starts to work. When it is working, I love the setup, and love the product. When it suddenly stops working on my network, or it starts to show the WiFi is disconnected symbol, or I get a message in Resideo staying that the thermostat disconnected from WiFi, I get really frustrated. That is saying a lot, because I am a tech savvy person, who is not frustrated easily. The setup is the only reason why I am giving Resideo a one star. If not for this glaring problem it would have a 5 star rating. So please! Fix this issue!

Goes offline a lot like everyday and of course my other devices like ring and nest do not go offline only this one. It usually comes back on itself but when it doesn’t then I have to call. After numerous calls they still have no info on me when I do call. They don’t know what device i have nor do they have any record of my name or phone number. I have to give all that info again only to find out on the next call they again have no record of me. Would not buy again. When it’s offline u cannot control it from your phone when your away which is why I got it. They can’t walk you through an issue cuz their unsure what’s going on. Needs lots of improvements. Since they keep no records or notes of their customer calls when you call they want you to remove the device from the wall to see if it’s installed right. It is because I had it professionally installed. They argue with you even though you know that’s not the issue. It’s so extremely frustrating it’s beyond words. When I’m able to I’m going to replace it with something that works and does what it says it can do. Would not recommend at all.

We got the Honeywell Lyric thermostat because of the Honeywell reputation. Installed in our newly built home and it is a very nice looking thermostat that works fine manually. The Honeywell app for it is horrible. Can’t believe Honeywell would put out such an inferior, useless app for its product. VERY disappointed - we got the unit to be able to control it when we are away, but it doesn’t stay connected to our WiFi and Resideo is so basic and rudimentary - it does not have any features that mirror the device other than temp up or temp down. What a huge waste of money this thing was. Would return it if I could. Honeywell, if you care about customer satisfaction you should invest in better app technology so, at a minimum, all your devices features are accessible via Resideo . Would NOT recommend this device until Honeywell upgrades their app to have a stable WiFi connection and has significantly greater features on their app. Until that happens, this product is a waste of money if you’re need if flexibility and control when away from your home. Also, I rate customer service “0” because I called and waited for 30 minuets and was still “waiting for the next available representative” - VERY FRUSTRATED!!

I have three (3) Lyric Round 2nd Gen thermostats in two (2) separate homes. Everything worked fine for a couple years with their App and HomeKit. In the last six (6) months, then Honeywell App (iOS latest) and via Apple HomeKit has failed with numerous problems almost on a daily basis!
Customer Support is a joke with weird complicated “work arounds” to try to solve simple problems like thermostat being set to “Auto” temperature. Really? That was their main selling point two years ago along with Apple HomeKit integration. In the last six (6) months some of the thermostats would be seen and work on Apple HomeKit and others would not. I HAVE HAD TO RESET (factory setting and reconfigure) each of these three (3) thermostats numerous times! I think it’s poor Honeywell App integration coding with HomeKit, third (3rd) party customer support (Honeywell Corp selling Division) and lack of WANT by Honeywell to continuing to support said product, even though it has a five (5) year warranty!
I have everything from window blinds, outlets, etc that is a whole Apple HomeKit “smart home”. The Honeywell thermostats and their App integration with Apple HomeKit is the ONLY problem devices I have. Hmmmmmm
So Honeywell, in this environment, and stated above, who had the issue?

Installation of thermostat was fairly simple. Old app was more informative, the new app leaves a lot to be desired. Apple Watch app worked with the old app, but constantly says offline after the update. Emailed support, but have not received a reply. I installed this thermostat to lower my electric bill. I have the thermostat set at the recommended settings for efficiency, but since installing my electric bill has increased. Expected a much more reliable product from Honeywell.

Called as requested. Customer service was friendly. Stated they would escalate problem for solution. And that I would be notified by email with a solution and correction to the problem. No solution or correction, problem still persists. Did receive email the following day to rate customer service and resolution to problem. How do rate something that has not been resolved? Rating: Customer Service - Friendly, Solution - None! Still waiting for that email.

Still cannot get Resideo to work with Apple Watch!!! Still waiting for solution from Honeywell!!!

Installation was a breeze for me. I already had the blue C wire. Not as pretty as Nest or Ecobee, but nicer than my previous Honeywell internet thermostat, and much better priced. Set-up was a breeze, as well, with zero hitches. Obviously other have had major headaches. Not sure what accounts for the difference. Geofencing could be improved as Resideo only allows for one perimeter. I’d like it to change the temp when I leave and arrive my house, but also when I leave work so it can warm or cool the house by the time I get home. Apple Home (or HomeKit as many people call it) does this, but it’s a bit confusing to use two apps instead of one. My iPhone was consuming the battery quickly, until I turned off location services on the Lyric app and only allowed while using Resideo on the Apple Home app. It still knows where I’m at even even if I don’t have either app loaded, but battery usage is much better. Honeywell sent me a few “appreciate your comments” reply’s to my posting elsewhere. Hopefully this will translate into app improvement, and not just a corporate demonstration of responsiveness to make me feel good.

App or unit has too many issues. I just bought the Lyric T6, what I've noticed the temperature is not calibrated correctly (no option to change) I have a thermometer next to thermostat and its off by 1 degree. Also, I notice the temperature just up or down within seconds, when its not possible. Also, the outside temp doesn't not refresh in a timely matter, unless you click on it. Set up was done without app originally however those settings are not available through app. ie: Option to change how many times boiler turns on, default was 3 but now I can't find how to adjust. Also, its really a travesty there is no motion sensor built into unit. No option to turn off the LED display, stays on all the time. Other than these issues everything else is amazing and I will change to 5 stars if update is made soon.

UPDATE: looks like notifications can now be sent as text messages (if you use your phone carrier’s special email address that forwards to text). Thank you! Adding a star.

Old review:
A handful of houses in our neighborhood have had TENs of THOUSANDs of dollars in water damage from leaks. When there is a leak in my home I want to know! Here are long standing notification failures with Resideo: 1) push notifications are easy to miss. I get hundreds a day. Might as well whisper to me at a football game 2) no badge icon - ok, I miss the push notification but at least there is a badge icon to let me know there was a leak right? No. No there isn’t. 3) email notification - too asynchronous, I need to know NOW that my home is flooding 4) text message - this is the ONE way that would be useful but they don’t support it. “Oh, just have an email sent to your phone’s texting email address”, you say? Sorry, can’t. Lyric requires that the email address be validated and you can’t validate it because it sends an HTML message and the text app doesn’t like that.

The issue is with the Resideo app. It was working well until I switched to the new Apple phone. The app no longer updates the temp outside or inside the home. You have to keep logging in and logging out. This doesn’t help when I’m away from home and if the heat suddenly goes out, especially a cold weather vacation home. I can’t recommend the Honeywell T 6 Pro because of this flaw and customer service is not helpful

I can only sum up the app in 1 word USELESS

I just had to connect my T5 WiFi thermostat to a new email account. Since that the Resideo app won’t allow me to control my thermostat. It will only display the current weather from AccuWeather. Before this I was happy with the app. Now it’s useless to me.
