I recently purchased one of the Mysa smart thermostats on Amazon, then bought 8 more directly from the Mysa app (which had better prices). I upgraded my condo which has electrical baseboard heating. The Mysa products work exceptionally well; they are very well thought-out, with a very easy to use app. Installation went very well, particularly due to the lightning-fast responses I received from their customer service whenever I had a question. They consistently provided very clear and concise help. They even followed up later to make sure things were going well! I could not be happier.

Installed two in our cottage about a month ago.- Install was easy.- Connecting to wifi took a bit- I drove 20 miles away into a valley to test it out. My wife confirmed that the numbers were changing as I changed them in the app- I like how I can monitor temperature status from the app while I’m not there.- the app is simple enough and it has nice features built in to monitor cost, setting changes, current actual temps etc.Hopefully it works long term, but so far I’m happy.

This product worked exactly as I hoped. The install was easy and it looks really great against the wall. I caution that the app is a little unintuitive (ex. If you set a recurring schedule and you change the temperature of one day of the schedule, all of the recurring days will adjust. If you change the time, however, all of the recurring events will consider that a new different event and won’t adjust).I love the graphs within the app, which help me understand usage at different time. I also like the humidity tracking feature, though I don’t know how accurate it is.

I have a 70s era house with resistive electric heating so I have a thermostat in every room. I wish Mysa was cheaper so I could replace all my t-stats but for now I just put one into my largest zone (kitchen/dining room). The Mysa thermostat feels very solid and was pretty easy to install though the instructions aren't perfect. In my case, I had black/white coming from my electrical panel but my heater uses red wires. They didn't have this scenario on their instructions so I had to figure it out myself by using the black/white wiring instructions for the line side then the black/red wiring instructions for the load side. I got there in the end though.My main complaint is that according to their support site, there is no way to switch between Celsius and Fahrenheit on my thermostat. There is an option under my account in the app but it doesn't change anything. Seems really dumb and it has been a bug for at least 6 months now since the support article was updated 6 months ago. I did contact their support for an update on the issue and got a reply back from their AI support agent basically regurgitating what the support article said. I'll wait until next week though and see if a real person responds. It is the weekend so I wouldn't be surprised if they only worked Monday to Friday. I'll update this review if I get any more info.Update 12/8/2023: I guess they fixed the issue with not being able to change from Celsius to Fahrenheit but didn't update their support site or the AI autoreply bot. (There is a setting when you're viewing the thermostat you want to change.) I am quite pleased to see that the app tracks your electricity usage as well as the ambient temp and humidity levels. Updated my rating to 5 stars now with my only remaining complaint being the cost.

My home was built in 1968, and has a bunch of baseboard heaters. I’d been using other methods to heat the house since baseboard heat is expensive, and the old analog thermostats were either just ‘on’ or ‘off’. I found the Mysa thermostats via my power company who sold them to me at a subsidized price. Once I got a few and saw how good they are, I bought the rest from Amazon and have now installed them in every room.InstallationFor those of you who don’t read directions, do yourself a solid and at least glance at the wiring diagram and simple instructions that come with the unit. You’ll need to be SURE you’ve turned off the right breaker at the box before you start removing your old thermostat. I used a Fluke-branded voltage pen to verify there was nothing live before I inserted a screwdriver. Once you manage to not electrocute yourself, the rest of the installation is a breeze. The first unit took me about 15 minutes. Now I can install a unit in about five minutes.Set-upI’m iPhone-based, and had zero issues setting the unit up. Download their app, and it walks you through every step of the way. The app is very well thought out and intuitive, with a pleasant UI and common sense functionality. (As of this writing, there’s no dark mode yet, but I’m just picking knits.) You can add your thermostat to both the Mysa app, and any of the major home automation services. I use Apple Home and had no issues adding the units there.UsageThe units can be operated manually, or you can set up a schedule on the app. The scheduling is as granular as you want to make it, so if you need a room to go up/down in temperature five times in a single day, you can program that if you want. You can also set up heating zones to control multiple units at once. I have my living room and kitchen tied together, so they both turn on/off simultaneously.ImpressionsOverall, these thermostats are very well-designed, packaged, and implemented. It’s clear a lot of thought and care went into the design and testing, with end-user usability being a top priority. Full disclosure: I’ve only had these installed in all rooms for three days now. During that time, I’ve noticed MUCH more evenly heated rooms throughout the house. One super cool thing about these units, is they’re not just on/off, but can modify voltage to the baseboard heaters to only make them use as much electricity as is needed to keep the room at a desired temperature.Overall I’m pretty thrilled with these thermostats. They look great, they’re easy to use, are solidly built, and integrate well with existing tech. Time will tell how much money I wind up saving on my power bill, but they are for sure a worthy upgrade for my older abode.

Easy enough to install but was a bit too wide for the space we had intended to use it. We used it to control our 3 baseboards on the open concept living area with supplemental heat pump. The temp control is great with the ability to control via the app. We are no longer trying to find that sweet spot on the old school analog dial temp control. In the 3 weeks we have had installed we have used only 2kwh of electricity. A bit expensive but I think it will be worth it over the next few winters. The app does have a bit of an issue and requires a hard close with close all apps on my phone. Not a deal breaker by any means.

I could see the difference in electricity usage on the day I installed it.Installation is very easy.My house is 45 years old, it has two black wires and a white neutral wire.I couldn't tell which is Line or Load...If the Mysa doesn't turn on, try switching the black wires.It worked with me.The App is easy to set up. You can invite your family member to control the thermostat.There is no on/off switch with the thermostat itself, it is controlled by App.The thermostat looks simple, not noticeable. It will blend in your wall if your wall is a light colour.I will buy two more for the other rooms.Feb 9, 2022I bought four in total. My estimated electricity bill was over $650 for two months. Now, It dropped to $450. I am expecting to save more. It was a good investment.
