I was going to buy Nest Thermostat, but went with Honeywell because Nest has complaints about temperate not being accurate!
I bought Lutron Caséta Wireless switches because I trust switch from electrical company instead of a tech company. The hub was a pain to get connected but I don’t have to worry about quality of the switches. BTW, Lutron tech support is 24/7 US based. Switches are expensive, $50+, but I called on a Friday night and they diagnosed a three way switch problem was caused by my wiring mistake. Ten minutes later and working!
