When we put our pool in many years ago I was given the chance to put automation in but decided, "hey, why spend so much money on pool automation? It's no big deal to just get home, turn the pump on, turn a few valves and switch the heater on manually". And that's what I did for 10 years. Cold nights, running back and forth to the pump and heater. Then someone in the spa (usually my wife), "it's getting too hot or it's still to chilly. I don't want to get in yet. Back to the heater I would go. Then my x-brother-in-law, still a good friend and aircraft maintenance manager an pool guy on the side says, man you should put this automation gadget in. I thought, well why not. The kids are out of school and out of the house. Well when my B-I-L told me the cost, well jeepers, it was a lot less today than it was 10 years ago! I did install the system and wow, what a difference it has made. Out on a cold bike ride, or at the office? Not a problem. Whip my phone out and when I get home it's all ready the perfect temperature. And when that someone says what's the temperature, is it ready the right temperature? I can whip my phone out and say, is 98 okay? Yep, that's it. And if she gets in and it's still to chill? Wait right there honey, I'll bump it up a degree. I'm a hero! All I can say is today my this app automation is a no brainer.
