5.0 out of 5 stars The truly smart thermostat for non-central heating

2026-02-11    -Primo Geek

I've been annoyed for a long time that brands like Nest have no provision for baseboard/wall line voltage units. I had been waiting for the Mysa to come out and my patience has been rewarded. It installs in a jiffy and the app install process goes smoothly. I left for the holidays and was able to remotely turn on vacation mode from the airport. So happy about that one.Install - the wiring instructions are clear and I decided to handle the install myself. There was a bit of hiccup as the wiring in my walls was gray and black which did not match with instructions. I decided to not fully remove the old thermostat and instead moved one wire at a time. By using the indicators on the back of the old thermostat I was able to correctly connect the wires.App install - the install sequence is simliar to other smart devices. The app connects to the smart device using a wifi network being broadcast by the device. The app then passes on your wifi network information to the device. The device then connects to your wifi and the app reconnects to the device. I use WeMo devices and this process is much smoother than thiers. I do have to note that the app did crash once during setup but after restarting everything resumed.Usability - the temperature display and buttons are very large and bright. The brightness is adjustable from within the app and you can disable the buttons if wanted.Energy stats - this is great for the data geeks. It tracks temperature, setpoints, energy usage and even energy cost if you provide the local rate. It allowed me to select the most efficient setpoints.Overall it has been a great experience. Do I really need a smart thermostat? No Will I replacing all of my thermostats with Mysas? Absolutely.

5.0 out of 5 stars Solid Choice for Baseboard Needs

2026-02-04    -M. Smith

I purchased this one because I didn't want to go through the hassle of getting a Nest or Ecobee to work with my baseboard heating system. The Mysa unit does not disappoint for this need. It was easy to install (took me about an hour; I went slow) and came with installation hardware. Oddly, they didn't include a wire nut for those of us who have a ground wire (my garage was built in 2016). While no big deal, it seems like an odd omission considering it's roughly a 10 cent part. Thankfully, I was able to reuse one of the wire nuts from the thermostat installation I was replacing.The app for Android works well and has a simple, yet effective, interface for setting schedules and remotely controlling the device. A smart hub isn't required for remote operation, but one is needed if you want to control it with Alexa, Google Assistant, etc.The temperature sensor seems to be accurate... it closely matches another device I have in my garage workout room. What I didn't realize when I purchased this unit was that it comes with a humidity sensor as well. That also appears to function well as it began raining a few hours ago and I gradually observed a 10% increase in humidity.I only have two baseboard units in my garage, and I'll need one of these for each unit, which I consider to be the only downside. However, it's much cheaper than many other choices on the market, installation is a snap, and the app works well. I recommend it if you have baseboard heat.

5.0 out of 5 stars Now we have smart baseboard heating!

We love home automation. Most of our lights can be controlled by Alexa, and we previously had a Nest (now ecobee4 at our current home), all linked to our Amazon Echo devices. Being able to control the temperature from anywhere is a major convenience and now cannot do without it. No more getting up in the middle of the night, coming downstairs, turning on the lights to adjust the heat or AC, for example. Smart thermostats are also much more efficient at regulating the temperature. With our Nest, for example, it saved us at least $10-20 a month during heavy usage periods. I noticed on the very next electric bill.We wanted a smart thermostat for our sun room too, which has electric baseboards. Nest and ecobee are for low voltage systems only (24v), and I learned that there are only 3 or 4 choices in smart thermostats when it comes to line voltage systems (120/240v). And you really only have one choice if you want Alexa or Google Assistant compatibility -- Mysa. Mysa is designed and made in Canada, where the majority of homes is heated by high voltage systems. In the US, the opposite is true.Installation was relatively easy -- super easy, in fact, if your wiring matches the diagram. I asked an electrician on Reddit for help because our situation did not match the one shown in the manual's diagram. Now, I'm happily configured, and already I notice a huge difference. The old analog Mears thermostat was very high maintenance and annoying (so was our old White Rodgers digital thermostat). It did not regulate the temperate well at all and I had to constantly mess with the dial. Once the room got too warm, we'd have to manually turn off the thermostat. With the Mysa set to 70F, for example, the baseboards are now pleasantly warm and safe to touch. It has a proportional control algorithm and can regulate the power level so as not to heat the room too much. This is indicated by the flame icon in the app (1-3 flames, depending on power level). This is important because we have a toddler. Our old thermostat (Mears M602) didn't have this, and turned the heaters on full blast all the time. That's a terrifyingly costly 3000 watts and a danger for pets and kids.Cosmetically, the Mysa is a nice looking and sports a modern, minimalistic design, but it's somewhat thick. As a first generation device, it's a relatively basic device with much fewer features compared to more mature thermostats like the Nest and ecobee. It doesn't have an occupancy or proximity sensor (only temperature and humidity), for example, and won't light up when you approach it. I'd like for the buttons to provide some haptic feedback, like a click. Annoyingly, the app has an energy chart button, but when you tap it, you get a “coming soon” popup.Still, I'm very happy. I'm looking forward to the product maturing and seeing improvements in the future.UPDATE: 11/21/18 - The chart feature is now available and it's great! It shows the usage per day/week/month, and has a cost estimator. Knowing how much it costs to heat your home is important for obvious reasons. I've uploaded some screenshots. Looking forward to more improvements.
