Only shows data in year view

2025-02-26

by Rock Scuttle

I’ve been using the app for a week now and it only shows data on the chart in the year view.

The boxes under the chart do not show any data for the month, day, or week. If I tap the chart it shows data for the current month

If I can’t see the data this app doesn’t do anything more than I can do in the Apple Home app. I’m cancelling my subscription.

Doesn’t seem to be keeping up with devices

Nice app & unfortunately I bought a subscription before I realizied the app doesn’t seem to be keeping up with the Kasa devices. EP40 smart outdoor 2 outlet switch isn’t supported. Tried to leave an “issue” via github and after setting up a github account wasn’t able to.

Promising start for Siri with Kasa

2025-02-28

by Sashazur

This app gives me the #1 thing I wanted with Kasa, which is being able to control my lights with Siri. But unfortunately Siri doesn’t work right if you also have an iPad, and any “spaces” you had set up in the app on your iPhone don’t transfer. It was also confusing to figure out how to add Siri shortcuts to turn all my lights on or off in the app, so I used the Apple Shortcuts app instead. Finally please add support for the KL120 lightbulb.
