I have Google nest thermostats (not the "learning" one)I'm very happy with it.One downside is that the screen turns on by sensor and the only way to make it kosher for shabbos is to have the screen turn on only if you touch the thermostat, which means that you can't see the current temperature without going over to the thermostat and pressing it, somewhat annoying.
Or you can open the app on your phone. Or even ask Google Assistant.
