No longer works with Google Home
Main reason I bought was these work, or used to work, with google home. Somewhere recently it stopped worked and just shows as offline in Google
Not good
The app is always having problems connecting to the actual product it. In the middle of summer someone decided to turn it on manually and when I went to the app it would not turn off or go down. The actual product will also not manually turn off or go down which can result in very bad problems.
Becoming useless
Two of my six thermostats keep turning on, even though I have all of them set to “hold until you change it.” I turn them both off and they continue to turn back on. NO, no one is touching them, I live alone. This is clearly an app and/or hardware glitch and it needs to be fixed!! I do not need my heat running simultaneously with my AC, my utility bills are expensive enough!!!

Junk
Like everyone in recent reviews is saying. No longer works and tried pairing many times.
Now it’s just trash
Now it’s just trash
Pleased until the latest update
Thermostat is not responding and tech-support started with an AI bot.
Amélioré ne veut pas dire meilleur
La version précédente était meilleur. Pourquoi avoir diminué la grandeur des graphique de
Température pour mettre des bordure inutile?
L’application réagit beaucoup trop lentement. Quand le soleil se couche, la température diminue et l’application n’anticipe rien. Elle met plusieurs minutes avant de réaugmenter.
Pourquoi ne pas mettre un mode pour le ac split qui mettrait la thermopompe en mode ventilation lorsque le soleil plombe au lieu de simplement fermer le chauffage?

The new app is the best among all smart home apps I’ve used.
Easy, clear actions, friendly.
Useless after updates last year
These thermostats are useless now after the updates. Multiple messages left with an AI response. After many years of flawless operation, the updates made last year ruin them. I had to get rid of them as they increased my electricity bill by after 40%. Bought new Meross thermostats that actually work and already have a warmer house without baseboards running nonstop, with a 40% drop in kWh per day. Replaced all 6 of my Mysa baseboard thermostats.

Need a widget for the app
Please add a widget for the app so we can place all thermostats in one widget on home screen and change temperature without opening the app.
Lacks a room temp calibration feature
This Mysa “Smart” thermostat is smart in the sense that you can control it minimally from your phone, but beyond that it is rather “dumb”. Zero usage or energy tracking on the app, and no way to calibrate the room temperature reading. The latter feature would take a coder 15 mins to code into the app and provide a much needed adjustment feature. I won’t return this because it’s its not worth uninstalling but I am not impressed and I would not recommend this product.

Straight Garbage now!
Since the new update last year, these things a terrible. Never reaches set temps, always running and wasting electricity. Set a 9x6 bathroom to 66°, 5 hrs later it’s only 63° but heater never shuts off. I have 6 installed in my house and none work anymore the way they use too. It’s been 0°-15°f outside for over 2 weeks, and the house is freezing with thermostats set at 66°. They never reaching the set temperature and hovers around 63° without the heaters turning off all day long. Almost like the heaters are stuck in low mode. Save your money and buy something else. I now have to spend hundreds of dollars to buy new thermostats that actually work, after spending hundreds of dollars in electric bills because these things don’t turn anything off. Long time customer here saying that the recent updates over the last year ruin these, and I’m getting rid of them! After complaining since the beginning of fall, zero updates have been given, and each update makes them worst! These thermostats are straight trash now!

DO NOT UPDATE YOUR APP
If you are using this for a forced air fan in the new app update you have lost the option to change the settings between short, medium and long. It now seems it’s permanently set to short or medium which now has all of my mysa heaters constantly turning on and off. I updated the app just 2 days ago and it is SOOOO DANG ANNOYING. There is nothing worse than a company who has no concept for UX (user experience). I now find myself once again looking for other thermostats if i cant roll back the app update. What a complete failure.

App got more confusing in Summer 2025
Coming from UX Designer, this is a step in the wrong direction. Menus are more complex, there's more lingo and language that's difficult to understand at a glance, and I cannot even figure out where my existing schedules are. Please take another look at the design of this app.
Good thermostats
I have both the MYSA Baseboard and HVAC thermostats.
The Mobile App display for current temp and humidity are too small when viewing the individual thermostat settings.
Baseboard thermostats are really accurate.
The Thermostats hardware temp LED display should have user defined color settings such as blue red or green and not just bright white. Maybe even, auto change the display temp to orange for when calling for HEAT and blue when calling for COOL then back to white or green when idle.
HVAC thermostat won’t call for HEAT unless more than 1 degree below set point, which is frustrating to see the thermostat 1 degree below the setting and you can feel it too. Prefer to have a less than 1 degree HEAT call. My old Honeywell always kept temp exactly at set point.
FAN control should be independent from HVAC calls. User should be able to turn fan on or auto and not forced to either or. My old Honeywell allowed fan to be on AUTO and still allowed me to manual turn on the fan when needed without reconfiguring the entire HVAC thermostat.
HVAC thermostat needs EarlyOn feature so whole house slowly comes up to temp by set point time. This feature is assumed in all newer smart thermostats!!!
Support is stellar if you have a question or issue. But some expected smart features are missing.

Improve the App Please
We have 5 Mysa thermostats in the house and we love them but the app could use a lot of work. Like seeing usage would be nice to see how often they turn on. Like a report system kind of. The app does the barebones but the product is incredible. Just please improve the app
New update from last winter is garbage!
Whatever you guys changed from last winter to this winter made the thermostats garbage. No matter the settings, heaters do what they want. Set it to 66°, thermostats take 3+ hours for the room temperature to rise to set temperature, with the heaters on nonstop. These thermostats used to put out the amount of heat out of low, medium, or high based on ambient temperature. Now it’s like every baseboard runs on low, taking forever to heat a run. My 6x9 bathroom now takes 5hrs+ to heat up to the set point! Fix it, or I’ll have to get rid of all 5 mysa thermostats!!

5 Star support response
App display for current temp and humidity are too small when viewing the individual thermostat settings. But ok when viewing all the thermostats together. Baseboard and HVAC Thermostats are great though hardware temp LED display should have user defined color settings such as blue red or green and not just white. Maybe even, auto change the display temp to orange for when calling for HEAT and blue when calling for COOL then back to white or green when idle. Support is stellar if you have a question or issue.

Managing Schedules
Managing Schedules is ok but needs to be more intuitive. Kind of confusing creating a future schedule because it wipes out your current settings. Display for current temp and humidity are too small when viewing the individual thermostat settings. But ok when viewing all the thermostats together. App is a little buggy and needs thorough testing by developers. Baseboard and HVAC Thermostats are great though hardware temp LED display should have color settings such as blue red or green and not just white. Maybe even, red for when set to HEAT and blue for AC.

Please add more features to the app
Great product but the software is lacking. Please add series of event which allows multiple same events in different days to be edited
