This thermostat is cool. I'm more please with the fact I have air conditioning then the thermostat, no offense. The contractor and I spent almost an hour on the phone to get my phone to connect to the wifi and never got it. I did later after 1.5 hour
It's not reliable, disconnects from network all the time. Switching from Off to Cool mode isn't smooth, and occasionally, the Off Changes to Heat because of latency in the panel. Perhaps you need better software, and/or a much faster processor?
