Mysa Smart Thermostat LITE for Electric Baseboard Heaters 240V | DIY Install | Use w/HomeKit, Alexa, Google Home | Wi-Fi Programmable | Remote Control with Free App (2024)

I bought the Lite version to replace an existing thermostat for a single baseboard heater. The installation was pretty straightforward in my case - and the instructions were very complete, between the printed booklet and online information. They make it easy to contact support, although I can't comment on response time or helpfulness, as I didn't have to do so. Connection was a bit frustrating. After following the instructions for Bluetooth setup, I could see that the device was connected when looking at the admin screen for my router. However, the connection procedure continued to fail on my iPhone. I decided to create an online account on the Mysa website and try again. Success! So if you're having trouble with setup, give that a try. Once connected, it was easy to set the temperature format. It seems to accurately control our heater, and is quite sensitive. I haven't used any of the more advanced features like scheduling and such, as my wife uses this room at all different hours of the day and night. Construction is solid, and the design is sleek and simple. According to the literature, it should be compatible with a range of other high voltage (120 and 240 VAC) devices. Although there were a number of remote thermostats to choose from, the Mysa had all the features I thought we'd ever need, at a competitive price. The Amazon reviews also helped me choose. Overall, I really like this little unit, and I'm considering a Mysa thermostat for our furnace as well.

Unfortunately the first one I received was defective but Amazon sent me another one for no cost and it worked perfectly. This product is exactly what I’ve been looking for to control my 220VAC baseboard heater for at least 3 years. The user interface is simple and has many great features and it looks great on the wall and can be used to increase and decrease the temperature setting from there as well. Also, I worked directly with Mysa customer support when troubleshooting the first item and they also concluded that it was defective. Customer support was excellent and fast responding.

Finally installed. Very easy to do - just know your line from your load. Three wires instead of four but twist the neutrals together, works great. App is very easy to use. Eco mode takes down temp 1 degree per hour, works for us.

The first Mysa I brought was the more expensive version. I saw the LTE but wasn’t sure what exactly the differences were. I didn’t want to give up too many features, but I could live without some if it meant saving some dollars.Install was super easy like the V2 version. Just have to make double sure you kill the power going to the thermostat connection. 240v is no joke.The LTE. like the V2, seems well built. It’s a heavy, solid peace of equipment. It fit right into the box the old thermostat came out of. If you have other switches nearby this probably won’t fit in the space as the faceplate it quite large. This one has actual buttons (up and down arrows) you can push to make adjustments at the unit. The V2 has touch (digital) controls. The buttons are more responsive than the touch control. The LTE does NOT have an adaptive display so it won’t adjust brightness based off the ambient light. You can adjust the brightness in the app. I put this one in my living room so that brightness of the display is not an issue. If you were putting it in a bedroom I can see where it might be an issue if one prefers total darkness. The LTE does not display a humidity value. Not a dealbreaker for me as I know in the summer it’s humid and in the winter it’s dry. You also cannot track usage with the LTE. Again, for me not a dealbreaker. I mean it’s cool to see, but I wanted a smart thermostat so I can control it remotely, use voice commands, and see schedules. The V2 has the ability to group your thermostat into groups if you have multiple thermostats, but the LTE does not have this capability. I think this is one feature I might wish I had. For convenience it would probably be nice to make groups, like main house, bedrooms, and so forth. That way if you wanted to make a change for, say all the bedrooms, it would be a one and done change. I still haven’t changed out the bedrooms, but I can see purchasing the V2 models for more robust control.All and all I’m happy I jumped in and upgraded the old, original analog thermostats. The Mysa is definitely more attractive and its functionality is a game changer when it comes to having more precise control over the baseboard heating system. If you’re even entertaining the idea of upgrading just do it. I don’t think you will be disappointed.

Works well for my in-floor heading system in the bathroom. I had to replace my old thermostat to get something I could program and automate with Alexa. Easily installed and programmable. Now we have warm feet when we need it. 😁

Great product? Install instructions were step by step in the app and easy.App is very easy to use and program what you need. Connected to my 2.4ghz wifi flawlessly.Looks great on the wall. Classy design.Was easy to integrate with Google home and create a couple automations.
