What ecobee Smart Thermostat Enhanced owners say

“I set a max temperature range and the sensors cut off the ac if the slider is open for longer than 5 minutes. You can also add room sensors to it too, but I don’t have them and unsure if you can prioritize them, but I bet you can, the smart sensor is the room one you’re looking for. Overall pretty happy with it.”

“I tried calling their tech “support” line today and it was laughably bad. The lady didn’t even know the different models and even recommended I buy the Lite3 which is literally the only model that will not accept any accessory at all”

What Honeywell Home T6 Pro owners say

“I've had great experience with my Honeywell T6 Pro (Z-Wave). Pros: - It works 100% without internet / wifi - You can still expose it to the internet (and Google Home) via Home Assistant if you want - It works perfectly fine as a 'dumb' thermostat - Honeywell is a reputable thermostat brand compared to some sketchy brands you find in the 'Smart Thermostat'”

“When I logged into hass the next time it said "We found a new homekit device: Thermostat". Please note, I don't do homekit despite having all apple devices. Two clicks and a code read off the screen and I had a thermostat in hass.”
