Most smart thermostats were built for forced-air HVAC. Nest, ecobee, and the rest work great if you have a furnace, heat pump, or central boiler — but if you heat with electric baseboards, fan-forced wall heaters, or convectors, most smart thermostats won’t even power on. Mysa was built specifically for the line voltage electric heating systems millions of homes still rely on. The Mysa Smart Thermostat LITE replaces any 4-wire 120V or 240V baseboard thermostat — including old dial and slider-style mechanical thermostats — with a clean, app-controlled smart thermostat that trims electric heating costs by up to 26%. WHAT MYSA LITE DOES: Per-room scheduling, 7 days a week — heat only the rooms you use, when you use them Remote temperature control from anywhere via the free Mysa app for iPhone and Android Voice control with Apple HomeKit, Siri, Amazon Alexa, and Google Assistant Free monthly runtime report email — see which rooms ran the longest and tune schedules to save Geofencing, away mode, vacation mode, and ability to lock the control on the thermostat Works directly over WiFi — no hub, no bridge, no central controller WHERE MYSA LITE FITS: Bedrooms, living rooms, basements, garages, workshops, sunrooms, in-law suites, finished attics, cottages, and rental units. Anywhere with electric baseboard heat or a 4-wire line voltage thermostat that’s been driving up the hydro bill. DESIGNED FOR NORTH AMERICAN WINTERS: Mysa is engineered in St. John’s, Newfoundland by a team that uses electric baseboard heat at home. Every Mysa LITE sold by Mysa – Smart Thermostats ships with a 2-year manufacturer warranty plus lifetime access to our North American support team — real people, no chatbots, 7 days a week. COMPATIBILITY — CHECK BEFORE ORDERING: Works with 120V-240V electric heating systems and requires at least 4 wires (a neutral or second live wire) in the junction box. It does not work with low-voltage HVAC, central forced-air, gas or oil furnaces, heat pumps, or two-wire installations. Look behind your existing thermostat before ordering — if you see only two wires, Mysa is not compatible without an electrician adding wiring.
SAVE UP TO 26% ON HEATING COSTS: Create custom schedules for every day of the week, reduce temperature when you’re away, and warm up the house before you get home. Mysa’s in-app scheduling cuts electric-heat bills without sacrificing comfort.
CONTROL FROM ANYWHERE: Connects directly to your home WiFi — no hub required. Use the free Mysa app (iOS & Android) to change temperature, set schedules, and monitor every room from your couch, your office, or while on vacation.
WORKS WITH VOICE ASSISTANTS: Pair with Apple HomeKit, Amazon Alexa, or Google Home for hands-free temperature control. Say ‘set the living room to 20°C’ and Mysa handles the rest.
120V & 240V COMPATIBLE: Works with 120V, 208V, and 240V electric baseboard heaters, fan-forced heaters, wall heaters, and convector units. Supports single-pole and double-pole configurations.
15-MINUTE DIY INSTALLATION: Step-by-step guide in the Mysa app walks you through every wire. No electrician needed for most homes. Requires 4 wires (neutral or second live wire) — check your existing wiring before ordering.

Clean and esthetically pleasing
This thermostat is great, battery isn’t needed since its hard wired. This was a upgrade from my old thermostat. Very easy to install and easy to use. It’s compatible with the app and baseboard heaters only. Mounting to the wall was easy and it sits nice and clean against the wall surface.

Mysa Smart Thermostat LITE – Line Voltage Electric Baseboard Heater Thermostat 120V/240V
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.

Easy to install! Works great!
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.

Differences between LTE and premium version
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.

Perfect thermostats!
We bought 4 of these for our downstairs thermostats and so far so good! Had an issue with one of them not triggering at a certain temp and Mysa replaced it right away. Easy to wire in, connects to app easily and relatively inexpensive compared to other brands. Will purchase four more for our upstairs as well! Highly recommend!

Perfect and pretty
Had an electrician install because my wiring was old. I get tired of playing this old house. He had it done is 15 minutes each. Pairs very well with the phone. Looks beautiful. I finally know the temperature in my home and don’t have to look at nicotine stained guages from the 70s. They glow bright at night which helps with the nightlight situation. You can adjust that though. Easily turned them off for the summer, installed before the tariffs. They turned on the heaters right away and worked great, one room was blazing hot all the time, meaning the thermostat was bad. Good pricing, and I want smart home all the way. Electric baseboard heaters can only have certain smart thermostats and mysa was one of two when I was looking. Bought three, for each room that needed a new one, and they are sleek and small and just show the room temperature.You can set up a schedule on your phone. Turn off the thermostat for the summer. Monitor those weird snap cold days where it rains all week and the temp drops and keeping pets comfortable while away at work. Only for the heater, I dont have it for a/c. I have portable a/c units for this old house.

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!

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.

Instalation facile. Fonctionne bien. L affichage est pas super beau mais l éclairage est ajustable. Personnellement j utilise Alexa comme assistant de ma maison inteligente et je j espère qu Amazon développe des mise à jour pour rendre plus facile l utilisation. Avec 13 pieces intéligentes et 14 thermostat à la maison Alexa vie dans le cahots.. mais si vous en utilisez 2 ou 3 seulement vous Adorerez ce thermostat.

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.
