Smart Thermostat LITE - Line Voltage Electric Baseboard Heater Thermostat 120V/240V | DIY Install | HomeKit, Alexa, Google | Wi-Fi Programmable | App Control

Easy to install, app is great and installation tips helped me navigate my 40 year old wiring. App is good, good controls like brightness and lower and upper temps. I had some trouble trying to navigate my existing wiring but the app installation wizard helped me figure it out on my own. I was initially intimidated working with 240v circuits but the app made it easy. It looks great and I finally have smart controls on my thermostat. Installed with new cadet baseboard heaters.

The Mysa Smart Thermostat LITE was easy to install and immediately improved the temperature control of my cadet style heaters. The app is simple to use, scheduling works smoothly, and the thermostats respond quickly. The modern design looks great, and the upgrade has made my heating more efficient and convenient. These were part of an energy upgrade rebate program provided by our power company, so it's a win-win both ways.

Operates as promised, easy to install and setup. Quality is exceptional. Design is great and attractive. Worth the money.

5 stars ★★★★★ I replaced my old dumb dial thermostat with the Mysa Smart Thermostat LITE for my line-voltage electric baseboard heaters (works on both 120V and 240V setups), and it’s been a game-changer for comfort and energy control in my NYC apartment. What stands out: • Easy DIY install — If you’re comfortable with basic wiring (turn off breaker, swap wires, done), it’s straightforward with clear instructions. No neutral wire issues for most setups, and it handles single- or double-pole configs perfectly. • Smart features without the premium price — Wi-Fi connected, app control is smooth (schedule heating by room, set geofencing so it warms up before you get home), and energy tracking shows real savings—users report up to 26% off bills by avoiding constant running. • Voice control & integrations — Works seamlessly with Apple HomeKit (Siri), Alexa, and Google Home. “Hey Siri, set the bedroom to 70°” is super convenient on cold nights. • Sleek and modern look — Clean white design with LED display and mechanical buttons—looks way better than the old beige boxes and blends into walls nicely. • Reliable performance — Handles up to 3,800W @ 240V (16A max), so it covers most baseboard or convector heaters without hiccups. No batteries needed, and the connection stays solid. It’s the “LITE” version (more affordable than the full V2), but it doesn’t feel stripped down—still gets you programmable schedules, remote access, and smart home smarts. Perfect for secondary rooms, rentals, or anyone tired of manually cranking baseboards. Only tiny nitpick: The app could add more detailed usage history logs (like exact on/off times), but that’s a minor want—core functionality is spot-on. Highly recommend if you have electric baseboard heat and want to make it smart, save money, and control it from anywhere. Already eyeing more for other rooms. Solid value and peace of mind all winter long! ❄️➡️🔥

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.

I hesitated spending the extra money on this and was just going to get a basic programmable thermostat for the baseboard heater in my addition, but gave it a shot anyways. Turns out I made the right choice. The unit is nicely built and doesn’t look/feel cheap. It’s a good value for the price. Design is simple and connectivity was quick and I can lock the buttons so my kids don’t mess with it. I’ve set up and installed a good amount household WiFi devices…The Mysa app guide is hands down one of the easiest and best to follow along. Definitely glad I went with this vs a cheaper option.

Looks much nicer than the last thermostat. Easy to read temp form a distance. The app is also intuitive and easy. It works well with a electric baseboard heater.

What a great thermostat! Aesthetically pleasing, simple, clean design. The smart features are very handy (which I was pleasantly surprised about as I hadn't fully read the description beforehand!). I currently have it set to eco mode which is nice add it allows the temperature to fluctuate minimally to save power. The install was simple - just 3 quick wires attached to the back of the unit. Once I downloaded the app, connection to my phone was quick and painless. Had the whole thing installed, connected, and running within 15 minutes! I'd recommend this thermostat to anyone with electric baseboard heaters looking to upgrade what they can!

Perfect! Works 100% as described. Easy install. Easy app. Easy programming.

I was about to send this back with a nasty review as it got hung up while I was installing it on the app. Came back the next day and tried again and it installed easy as pie. Must have been a glitch the day before. The unit and the app work perfectly. Looks great on the wall and programming it easy and intuitive. Very pleased.

Had a bit of difficulty getting the wiring right the first time, but support was very helpful. Otherwise, the product works great. Love being able to schedule when the heating goes on and off, and as a bonus, I get a monthly report from Mysa on how much it was used.

Mysa are stylish easy to use. Love those smiley faces and check that appear when all things are setup good. 2 things could be improved by Mysa: The app is great but the energy usage dashboard doesn't offer enough flexibility. No interoperability with other platform. Their competitors are! Let's go Mysa we are in the age of smart homes For those 2 points I give 4/5 instead of 5/5.
