    • 5.0 out of 5 stars Well designed, easy to install

Very well designed thermostat, with a really slick and smooth installation. Of course, before installing it, I had to take a look inside. It's really well designed, and also contains a lux sensor and a humidity sensor, which I did not realize when buying (but are a nice plus). An ESP32 is used for networking, so it should be pretty easy to convert to ESPHome if/when this company goes bankrupt. The device also works great with HomeAssistant for local-only control. I was notified the device existed, I typed in the code from the manual, and now I can access it & automate it. On the other hand, the app, while functional, has a couple dark patterns. You are unable to use the device without an account, which is entirely unnecessary since the device works just fine without the internet. It also subscribes you automatically to their pointless mailing lists, and doesn't give you an option to opt-out on signup. ... show more

    • 4.0 out of 5 stars Nice, but…
I just installed the Mysa in floor heat thermostat. It’s esthetically very sleek and nice looking. The reason I gave 4 stars is two-fold. Whoever designed where the little thermostat wires attach into the unit should be fired. It’s at a terrible angle to try and maneuver those two sensor wires to the back of the unit. I tried to post a video, but just know it’s annoying. Second, the thermometer nub that you are supposed to hide under your flooring to give precise heating control is enormous and I actually couldn’t make it work without buckling my luxury vinyl when laid over top. I didn’t measure, but that nub has to be close to 1/4” thick. On a floor with concrete, you would have to chisel our some concrete in order to get the flooring to lay flat over top of it. I’ll still use the unit and see how it works by using the ambient room temp, but have read that method results in large fluctuations of temperature. I do like that the unit does a good job of telling you if there’s an error in the system somewhere. I had a broken wire connection within the wall leading to the pad heaters i used and this thermostat. It identified an H2 code error that helped me determine the issue. The quiet warmth brand that I have in another room would not identify that there was any issue and I wouldn’t have so easily diagnosed the issue. ... show more

    • 4.0 out of 5 stars Initial one was defective, but replacement has been great!
The first one I received kept tripping the GFCI for an unknown reason. The company immediately offered to replace it. Although it did take about two weeks to arrive (shipped from Canada to US), the replacement has worked perfectly. The native app is great, and the information it provides is useful. Two (minor) things I’d change: - the touch surface of the faceplate takes a firm press to activate. A “lighter touch” would be nice. - the temperature of the floor as displayed on the thermostat never seems to match the set point - it’s always 1 degree cooler. I realize this is probably due to rounding or it being “72.9” instead of 73, but it’s a bit disconcerting to set the thermostat to 73 degrees, and never see that temperature achieved on the display - it just makes me think it’s broken (when it isn’t). ... show more

    • 5.0 out of 5 stars One tricky part of install
Bought the Mysa In-Floor thermostat to replace a Schluter Ditra-Heat RT (no wifi). Main problem I was trying to solve is that the Schluter sometimes turned on by itself after a power failure, and in a remote house that was a big problem. Mysa is a much more elegant thermostat. Easy to install, simple interface. Obviously with WiFi, can be controlled remotely (Schluter has a wifi version but felt Mysa more elegant for a residential installation). Switching & installing was easy with the exception that connecting the floor heater sensor to the thermostat terminal was surprisingly difficult. Sensor wire is typically very thin and malleable, and the terminal port is sort of awkward to get to (and tiny), so threading the spindly wire into the terminal was a challenge. Once done though, connected to wifi and the android app seamlessly, and I can now remote control and turn off (and on) the floor heater. Three more suggestions (1) Mysa should try to help identify the proper floor sensor setting by showing a list of floor heater makers and the appropriate sensor settings (2) Mysa should include a tiny screwdriver for the floor sensor terminal screws, they are much smaller than what a typical household screwdriver would fit, and (3) their documentation for the app is in the form of faqs and can be sort of not helpful for a holistic overview or for specific questions. Granted the app is fairly intuitive, but for example, for the simple question of "how do I turn off the power to the floor heat", it is not completely clear what actually achieves that. There is a FAQ answer on the website, but those instructions don't actually match the app (maybe it matches the iOS app?). ... show more

No one is there to help with general problems. You can send an email and hope they get back to you. You can try their subreddit where one person is responding... For me, and for whatever reason, the thermostat wouldn't go above 84. Supposedly that's their out of the box preset. Nowhere in the documentation does it say this. I couldn't go above 84 for hours. The next day, I can? So far it's working correctly but I worry about when something goes wrong ... show more

    • 1.0 out of 5 stars Fundametal bugs can't be fixed timely
I bought 9 of these for my house. Overall it is easy to install and use. One annoying thing is if you want to pair it with Homekit and your contractor mixed up the pairing code, you have to remove the thermostat to access the pair code. why can't it be exposed via the UI or app? It has another annoying bug where the thermostats would always show the floor sensor temperature instead of the room ambient temperature. It's annoying if you want to use the sensor for home automation, the sensor isn't exposed. The issue has been around for over a year and they still don't have a fix for it. Given how expensive these units are, the company support and test coverage for such fundamental feature is pitiful ... show more
