One of the best thermostat products I have ever purchased. I have several of them which I use to control Cadet 240v electric heaters in my garage and cabin. They are very well designed, easy to install and set up and have been very reliable. I appreciate the ability to monitor not only the heating usage but also the power drawn. They are very easy to integrate into Home Assistant, HomeKit, or just standalone with the Mysa app.

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?).

Just installed this today, so far it works fine. Takes a while to heat up my floor but that may just be an issue with the heater mesh install which was done before I bought the house I'm in. Previous thermostat was a suntouch from 2004 that was crumbling apart and had a very bad coil whine. Install was easy pretty easy. I like that there's a plate to install and the brains are on a removable faceplate. It made the install very easy. Before you install this (but right after you remove your current thermostat if you are replacing it) measure the resistance of your thermistor/floor temp probe, you'll want to validate the temp probe resistance setting after you add the thermostat to the app. The instructions do not point this out. Adding to homekit was a nightmare. Definitely set up the thermostat from the app using the homekit method. But you definitely need to have your wifi network properly configured. With the way most smart home devices work you can rarely blame the manufacturer unless if they're using a terrible bluetooth radio and pairing with a hub or appletv (I'm looking at you 3rd gen august smart locks). Firstly you should be using a separate network for IoT devices, for security and compatibility purposes. You can google why you should have your IoT devices segmented away from you main network. There are plenty of videos and articles that will explain this in leighman's terms, and there may be videos for your specific (or similar) router on how to set this up mostly. These are the settings that I needed to have for my IoT network to get this to connect properly via homekit. I am using a Ubiquiti Unifi based network with a UDM pro and 3 Access Points. - Turn off IGMP snooping - Turn on Multicast DNS - Only have the 2.4 GHz band turned on for the IoT wifi network - Both multicast management options unchecked - Uncheck minimum data rate control - Have the 2.4GHz density slider all the way over to 1Mbps - Security protocol set to WPA2 (another reason to have a separate IoT network) This is using an ESP32 at least from what you can see on the back of the faceplate as the chip is there. Overall I'm confident in this device and it looks great in my master bathroom. All things said and done, it works great so far! I will update this review after a while or if I run into major issues.

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.

I was really excited about this thermostat as a replacement for my current T-stat that did not have WiFi or programmability. PROS: - Great looking with nice interface (I was only able to experience the touch-sensitive display) - Very easy to install CONS: - Show-stopper in my case: The device was not able to connect to my WiFi router (Netgear Orbi). I will spare you the technical reasons but it would have been great to know that the device was not going to work with my router before I invested time in purchasing, installing and wasted a lot of time in trying to configure. Apparently, there is a list on their website with the list of unsupported routers. They claim it's a short list, but it includes Orbi which has become very popular these days, as well as ALL of XFINITY/COMCAST routers, which a whole lot of people use. It's a shame that I couldn't use these T-Stat. But a bigger shame that the company wouldn't highlight the compatibility risk on the Amazon ad.

I built my own heated floor system with the QuietWarmth super slim heated flooring mats and added this Mysa thermostat to control and power the floor. It was pretty straightforward to setup and it works great. It was almost half the price of the 'branded one' you are supposed to use with the floor... Plus it's Homekit compatible so I have it running perfectly with my Smart Home setup running under Home Assistant. If you don't want to be geeky you can control it via the wall thermostat (my wife), and if you want to be geeky (me) you can interconnect it with and control it from your smart home system... Triggering it via occupancy sensors etc.

I purchased this Mysa in-floor heating thermostat in August 2022, and it has only been used during the winter months. After less than two seasons of very light use, the unit suddenly displayed an H2 error and stopped working entirely — right after I updated the app. I confirmed the wiring and floor heater are both fine (tested with a multimeter), and I even performed a full factory reset, but the error remains. It’s frustrating that a product at this price point would fail so soon, especially with such minimal usage. While Mysa’s features are nice, I can’t recommend it based on durability. I’m switching to a SunTouch SunStat thermostat, which is built specifically for floor heating and has a stronger reputation for reliability. If you’re looking for something long-lasting, I’d suggest skipping this brand.
