Mysa Smart Thermostat for Electric Baseboard Heaters 240V | Remote Control with 100% Free APP | Easy Install | HomeKit, Alexa, Google Home | Wi-Fi Programmable | Temp. & Humidity Alerts

Excellent product for older homes
My home was built in 1968, and has a bunch of baseboard heaters. I’d been using other methods to heat the house since baseboard heat is expensive, and the old analog thermostats were either just ‘on’ or ‘off’. I found the Mysa thermostats via my power company who sold them to me at a subsidized price. Once I got a few and saw how good they are, I bought the rest from Amazon and have now installed them in every room.InstallationFor those of you who don’t read directions, do yourself a solid and at least glance at the wiring diagram and simple instructions that come with the unit. You’ll need to be SURE you’ve turned off the right breaker at the box before you start removing your old thermostat. I used a Fluke-branded voltage pen to verify there was nothing live before I inserted a screwdriver. Once you manage to not electrocute yourself, the rest of the installation is a breeze. The first unit took me about 15 minutes. Now I can install a unit in about five minutes.Set-upI’m iPhone-based, and had zero issues setting the unit up. Download their app, and it walks you through every step of the way. The app is very well thought out and intuitive, with a pleasant UI and common sense functionality. (As of this writing, there’s no dark mode yet, but I’m just picking knits.) You can add your thermostat to both the Mysa app, and any of the major home automation services. I use Apple Home and had no issues adding the units there.UsageThe units can be operated manually, or you can set up a schedule on the app. The scheduling is as granular as you want to make it, so if you need a room to go up/down in temperature five times in a single day, you can program that if you want. You can also set up heating zones to control multiple units at once. I have my living room and kitchen tied together, so they both turn on/off simultaneously.ImpressionsOverall, these thermostats are very well-designed, packaged, and implemented. It’s clear a lot of thought and care went into the design and testing, with end-user usability being a top priority. Full disclosure: I’ve only had these installed in all rooms for three days now. During that time, I’ve noticed MUCH more evenly heated rooms throughout the house. One super cool thing about these units, is they’re not just on/off, but can modify voltage to the baseboard heaters to only make them use as much electricity as is needed to keep the room at a desired temperature.Overall I’m pretty thrilled with these thermostats. They look great, they’re easy to use, are solidly built, and integrate well with existing tech. Time will tell how much money I wind up saving on my power bill, but they are for sure a worthy upgrade for my older abode.

Full version vs. Lite version
This thermostat is easy to install, configure, and operate. It is significantly better than a similar Mysa baseboard heat thermostat, known as the “Lite’ version. This thermostat can send email alerts for extremely high or low ambient temperature conditions, but the “Lite” version cannot do this. So far the unit is working perfectly. Also, this unit only switches one of the two hot lines of a 240 volt circuit. In the United States, we normally switch both hot lines. This is not a problem for my application, as the thermostat is switching the 120 volt coil of a double pole 240 volt relay.

Does what I was hoping. Unit has a lock mode so it can’t be changed from the panel. Shows power consumption with day and month charts. The app is very easy to use and set up. Now I just need 6 more….

Installation was straight forward – if you have the proper wiring, this is a 10-minute job. It looks clean and simple, very classy.My only complaint with it is that it has limited functionality when part of a smart home system (connected via HomeKit). It provides temperature reading and humidity level to HomeKit, as well as the ability to change the temperature setting, but it doesn’t expose the power consumption, the ambiant light sensor, the proximity sensor and it’s not possible to control the brightness of the display on the unit via HomeKit.I don’t know if Mysa actually wants to keep this data to themselves to force users into their app or if they just didn’t spend the resources to implement it, but if they did in a future update, it for sure would be a perfect 5 stars and no complaints at all!
