Would be zero star. Get Nest
Also, I have 2 additional temperature sensors in the house. I wish it had an option to set thermostat to operate off of one of the additional sensors at the push of a button instead of only on schedules.
I have had this for over a year now. I have all automation settings and smart optimizations turned off and the thermostat will still change the temperature on its own. I hate sitting in my living room perfectly comfortable and a few hours later wondering why I’m suddenly freezing. I look at my thermostat and it has set its self 3 degrees cooler. I’m soooo annoyed and may either switch to Nest or just a dumb thermostat.
Spoke with Ecobee support and they said my issue is tied to the sleep schedule (that I have disabled) changing the temperature. Schedules don’t work in my house as I have people that don’t go to bed until others are about to wake up for the day. They said you can not delete schedules and go full manual control.
A year later and I still hate this product. It still changes settings on its own. I went all summer with it working fine. It got unusually cold outside this week, and I had to turn the furnace on. I set it to 72 and woke up on the morning to it being set to 67. I DO NOT WANT IT TO CHANGE IT’S SELF. This is the single most frustrating piece of technology that I own!
Update: Two years later, had it working decent for a while. Has randomly started to change my set cooling temp in my house from 70 to 77 in the middle of the night. I love waking up sweaty. I haven’t changed anything. Support blames Apple Homekit. My phone is the only Apple product controlling it, and I only use the app. Not sure how Homekit is calling for temp changes while I’m sleeping and automation is as off as it can be. I still wish automation could be fully disabled. Time to abandon this company completely. I am glad I have stopped so many customers of mine from purchasing Ecobee.
It will be nice once I learn it.
Scheduling
Simple recommendation: Remove all the rules you got around scheduling, let users decide/create their own schedule, only disallow overlap, or gaps, do not EVER AUTOCORRECT coz your current logic in simple words Blows big time.
Decent but could be so much better
I also would request custom HOLD times that should be very simple to do. Just the option to set any custom time at the time of changing the temp instead of just offering 4 basic options.
It does what it needs to do
Stay Far Away
I can’t imagine how this app got a good rating
Schedule is the WORST
They say there are ways to override it but it does not work all the time.
Stay away
Time adjustment
Ecobee+
Wow
STOP TURNING ON SUPPORT GRID INTEGRITY ON MY THERMOSTATS!!!
Third time ecobee has done this! STOP IT! It’s not my job to help the grid. It’s the state of Texas job to fix the damm thing!
No Ultra Complication
Still not back? What are you people doing to fix this problem that you caused?

This lie was in February:
“Thanks for flagging this! We’re aware of the issue and have completed the fix which will be included in the next app update. We appreciate your patience and feedback.”
It’s now nearly mid-May. [update: early September 2026; still nothing]

HEY!! Anybody!!! WHEN IS THE COMPLICATION FOR THE ULTRA GOING TO BE RELEASED?! NO RESPONSE FOR MONTHS!!!!
Is anybody paying attention? No? Figures, this company’s service is the worst. Horrendous.

Out of the last fifty reviews for this thing only three have five stars —— a great many are one star. This tells you all you need to know about how abysmally bad this company is. So sad, had such potential, probably some billionaire owns and now ignores it. The worst of the worst.

I have Activity Alert on, someone came through my door, and I received the alert well more than five minutes later. This is seriously bad for security! What a pathetic piece of garbage.
Defective thermo & Sensors
they are all innocuous
