ecobee Smart Thermostat Premium

Scored on 111 verified owner verdicts, from 628 comments read across 7 communities
TL;DR
Owners praise the Ecobee Premium for its premium feel, large display, deep HVAC customization, and solid HomeKit and Home Assistant integration, and many report lower energy bills. The most common gripes are over-aggressive automation that people end up turning off, onboard temperature readings that run off by several degrees, and quirky heat-pump or dual-fuel staging. Expect a learning curve, and don't lean on the air-quality sensor for accurate CO2.

61% of 111 verified owners recommend the ecobee Smart Thermostat Premium, based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.

Yet this $250 thermostat is just making random guesses at CO2 based on VOC which don't always correlate well.

As nice as my Ecobee premium was, it was overwhelming with all of the bells and whistles and addons and smarts and menus and … bleh.

It worked great.

That was the primary reason I switched to ecobee from nest, it’s not an exaggeration to say it was driving me insane how much it was triggering the AC to only have a 1 degree differential

Reddit— neutral

when I upgraded to the premium version of the ecobee it was not programed and installed properly which I was losing my savings

Reddit▼ don’t recommend

the ecobee will report anywhere from 1-6 degrees or more of temperature swings after turning on the ceiling fan.

Reddit— neutral

I wish the ecobee Smart Thermostat Premium would display the time on the home screen.

YouTube▲ recommend

Glad I went with the ecoBee Premium thermostat.

Air quality sensor on my ecobees aren't reliable as one would expect.

YouTube▲ recommend

Much happier with the ecobee for the air quality monitoring, better circulation fan controls, and easier to configure schedules.

I just installed an Ecobee Premium. I have a heat pump with gas furnace backup. My heat pump has always run into the low 30’s. Now it won’t come on until the outside temp is in the sixties. I’ve played with every setting and no go.

Reddit— neutral

I use the ecobee premium via homekit. It's nice and has a beautiful UI.

Reddit▲ recommend

it’s been fantastic. The cross-floor temperature tracking has been incredibly useful for heating the home at night to keep a comfortable temperature in the bedroom upstairs.

Reddit▼ don’t recommend

Ecobee has been the worst smart thermostat I have owned. None of the features of the Ecobee Premium have worked well for me. Temperature and humidity are 12-16 degrees/percent off. Siri integration is shit. HomeKit integration is shit. The app is shit.

Reddit— neutral

they don’t play as well with HomeKit. I also like the built in scene controls and ability to tie a camera to it without a subscription.

YouTube▲ recommend

Ecobee wins hands down in every category.

Reddit▼ don’t recommend

I have a few ecobee premiums with all the "smarts" turned off because the features make them irratic.

Reddit— neutral

I don’t really find the sensors useful and they don’t work the way you would think they should. But I do like the premium thermostat.

I couldn't fully appreciate my son's gift until I read your Review a few days ago and properly set everything up with 6 sensors.

Reddit▼ don’t recommend

while the Ecobee is consistently off by 5 degrees. Everything has been sealed, so there’s no drafts.

Reddit— neutral

a lot prettier than the Nest (gen 2) but not a lot different in functionality

Reddit— neutral

The Ecobee interface is confusing, but otherwise works well

Reddit▼ don’t recommend

Just installed Ecobee premium (w/ 2 Smart Sensors) and I am having issues with inaccurate readings on the temp sensor of the main unit. Much more erratic and larger variations than the Smart Sensors even when they are placed in close proximity to the main unit.

Reddit▲ recommend

Got my premium today as well. Rather than start a new thread Love it all around.

Redditⓘ good to know

My ecobee smart thermostat premium acts as a Siri speaker. I can talk to it as if it’s a HomePod basically.

Redditⓘ good to know

Last night I swapped a Nest for Ecobee Premium. I did not download the app until after the physical installation, which was an error.

Redditⓘ good to know

i just switched to Ecobee Premium smart/Wi-Fi stat with extra room sensors

Redditⓘ good to know

I've since tweaked some of those settings and everything seems fine now. I can't say if I configured everything properly, but I'm at least warm now.

Redditⓘ good to know

I just got the premium after replacing my original ecobee3. Was going in for the enhanced but the premium was marked for clearance and was $30 cheaper than the premium, so why not?! I have mine exposed to HomeKit through home assistant so I can’t seem to get Siri to work, but it was so slow when I tested it it didn’t bother me.
