My wife and I are buying a house. I currently have one Nest (2nd gen). We need to replace two thermostats in the new house. The current debate is, should I buy one more Nest and be done with it? Or should I switch to Ecobee where I'd have to buy 2 new thermostats? I'm interested in having HomeKit enabled devices which would only be the Ecobee. Is HomeKit comparability worth it? Has anyone here used both and have a recommendation for one over the other? Appreciate any advice.
