Mysa Smart Thermostat for Electric in-Floor Heating 240V | Class A GFCI | WiFi Programmable | App & Voice Control with Alexa, Google, Siri | No Subscription | Easy Install

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?).

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.

Easy installation, great esthetic, and good streamlined app UI.As of this writing (2024), the app includes basic cost tracking that, given a single $/kwh will summarize your heating expense over a period. Would be spectacular if they augmented it to include different pricing periods, and take it a step further to enable (even a basic) algorithm that tries to optimize usage during off-peak periods.Loses one star because, from what I’ve read, they don’t intend to open up any kind of API. I can’t begin to guess how home automation systems will evolve over the years, but if they opened up the platform I’d feel re-assured it will work with anything that comes along in the future.

Bought to replace a 20 year old thermostat for my in floor bathroom heating. Wasn’t sure I needed a wifi enabled floor thermostat but the price point made the decision to get it easy. Installed easily though it took me 2 tries to get the existing floor sensor to work, but did it and didn’t need tech support. Connected easily to my iPhone and wifi system and even got the geofencing to work. I’ve probably changed my schedule more in one month than I did over 20 years with my previous model, but it’s easy and works well. I prefer the face plate light on but it does throw a bit of light (even at 10% brightness) so I close the bathroom door at night
