Mysa pushed out a bad firmware load that bricked all 5 of my thermostats. No support in over a month. If this was winter they would have potentially caused serious damage to my family and our house.Instead of these cheap and poorly made systems check out Schluter Systems for a quality product and great support.

Excellent follow-up & help from Manufacturer...who is Canadian. You do need a 2.5 GHz internet connection to function with Wifi. I have Starlink internet...which has 5 GHz (default) & 2.5GHz capabilities. You will need to 'split' the network... simple process in Starlink settings...for the thermostat to work.

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.

Have bought two of them, very satisfied. We had vintage thermostats for our heating floor and it was hard to keep it at a good temperature. With Mysa thermostats, we can leave it at a confortable base level and ajust easily the temperature on our phone or on the thermostat itself. Would recommend 100%

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.

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.

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.

The Mysa in-floor heating thermostat was pretty simple to install. It was to replace a non-functioning Nuheat thermostat with the Mysa unit. The in-floor heating that I'm using is a 120V based Nuheat pad that's 21 years old. I didn't use the included Mysa in-floor thermometer and just used the original Nuheat provided temperature sensor. I didn't even have to configure the voltage or the temperature sensor resistance. The Mysa unit figured it out for me.What's nice is that I have 3 Mysa baseboard thermostats and now this in-floor heating thermostat in a 1 bedroom basement suite. I don't have a separate electrical meter, but, the iOS/Android app allows both me and my tenant to monitor the electical usage. I did that by using the provided 'sharing' capability in the app. Only thing that I needed to do was to indicate my $/KWH in the app and the app shows not just the KW consumpution in realtime, but, the cost incurred daily/weekly/monthly for each of the thermostat. So, the tenant just includes the additional electrical/utility amount to his rent at the end of the month. The transparency that this provides is great as there is no guessing of the electrical usage as it relates to heating the suite.

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?).
