Exactly what I needed

I have an elaborate smart home and I use Home Assistant as my main hub. While there are ways to make HA work with my watch, it’s very convoluted. This was simple and easy and I was up and running in a few minutes. As a bonus this app doesn’t collect any day at all. Well worth the $3 cost for this app. It’s only been a day, but it’s a great app purchase so far. With a single tap of my watch, I can control the temperature. Not sure what more you could ask for.

Much better than Nest app

Now if he Mark would just write an app for my Honeywell thermostat.

Works w nest 2020 thermostat

Love this ! Made my nest 2020 display removing humidity on my phone and Apple Watch so I can better control my temps and humidity. Thank you!

Works great!

This app connected right away and works perfectly with my Ultra 3 watch and my Nest Gen 4. I’m able to control my thermostat right from my watch. The feedback response is great. Simplistic and works great!

Random behavior

I set up the short cuts but Siri still will only work if the app is open, defeating the whole purpose of having the app. It also has been building a schedule with temps I never set it to. There is no trial period and it doesn’t work…
