My problem with smart thermostats is the user interface couldn't be more awful. It's just nuts. You cannot do anything without the squinty manual in one hand and the squinty touchscreen in the other. So, you finally get it programmed. Then you want to change something, and boom, start all over.

I gave up.

I use a simple dial the temperature, turn on/off thermostat. I turn it off when going to bed, turn it on in the morning. Very happy.
