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

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. Installation For 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-up I’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. Usage The 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. Impressions Overall, 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.

Amazing product and great tech support service from Mysa! I had the old knob style thermostat for baseboard heating in 6 different rooms at two separate locations. The knobs eventually broke and I ended up replacing them over and over. I was fed up with this and wanted something more modern that I could also monitor remotely. I use the baseboard as a backup heating system to a heat pump and wanted a reliable thermostat that I could program and monitor remotely. These are fantastic. I am not an electrician so was worried about installing a 240V thermostat. I found the correct breakers to power off the existing thermostat and each time verified that the power was off using a meter. You can take a picture of your wiring setup and tech support can help you with the connections as well as trouble shooting. Generally when you send a tech support email to most companies you are lucky to get a response. My response was given on a Sunday in 6 minutes from when I asked my question. Process that for a minute - 6 minute response on tech support is “real time” and on a Sunday no less. I was able to continue the job without any delay. Tip: Make sure to take a picture of your current wiring setup as that can come in handy if you ever need tech support. The app is intuitive, easy to use, and it’s very easy to install and connect to the thermostat. Once connected you can adjust the brightness (can even turn it off when you’re sleeping and have it “awaken” when you approach), temp display in F or C, and various programming options like most smart thermostats. My version also has humidity level which I find useful for monitoring damp locations. Great product and great service. Extremely happy!

We have a number of Nest thermostats and have been impressed with their simple appearance and great functionality. Alas, they cannot handle high voltage systems like baseboard heat. There aren't terribly many options. We went with the Mysa. Their appearance is almost primitive by today's high-res standards. Very simple. However, unlike some other options, you are not totally at the mercy of an app. Temperature can be adjusted up and down on the thermostat, itself. I really wanted that. As for the app, it does most anything you can imagine with scheduling, pre-heat option, energy consumption, etc. More than meets my needs. One thing that worked out rather nicely are the dimensions of the thermostat. My heater runs the length of a wall with a bank of windows above it. There is no really good spot on the wall to place the thermostat. When I removed the old, rotary dial thermostat, I found the hole just right for the Mysa. I had to put in a couple of spacing blocks so I could screw on the backplate of the thermostat, but that was it. No installing an electrical box. No snaking a wire down to the heater. Neat and clean. And the Mysa works great. Nice!

J'ai récemment installé le thermostat intelligent Mysa et je suis très satisfait de mon expérience jusqu'à maintenant. L'installation a été facile grâce aux instructions claires fournies. L'application associée offre toutes les options dont j'ai besoin pour contrôler le thermostat à distance et programmer des horaires. J'apprécie particulièrement la fonctionnalité de suivi des coûts qui estime la consommation énergétique de mon chauffage selon mon utilisation. C'est un bon outil pour mieux comprendre et optimiser la consommation de ma résidence. Dans l'ensemble, le thermostat Mysa est un bon investissement abordable pour rendre une résidence plus intelligente et contrôlable. La simplicité d'installation et d'utilisation, jumelée aux nombreuses fonctionnalités, en font un produit que je recommande sans hésitation. Pour le prix, vous avez accès à un thermostat programmable et contrôlable à distance complet et efficace.

I could see the difference in electricity usage on the day I installed it. Installation is very easy. My house is 45 years old, it has two black wires and a white neutral wire. I couldn't tell which is Line or Load... If the Mysa doesn't turn on, try switching the black wires. It worked with me. The App is easy to set up. You can invite your family member to control the thermostat. There is no on/off switch with the thermostat itself, it is controlled by App. The thermostat looks simple, not noticeable. It will blend in your wall if your wall is a light colour. I will buy two more for the other rooms. Feb 9, 2022 I bought four in total. My estimated electricity bill was over $650 for two months. Now, It dropped to $450. I am expecting to save more. It was a good investment.

très bon thermostat. Mais attention fonctionne seulement avec 2 câbles 2 brins (nouvelle construction) . ne fonctionne pas pour vieille construction avec 1 câble à 2 brins

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!

This product worked exactly as I hoped. The install was easy and it looks really great against the wall. I caution that the app is a little unintuitive (ex. If you set a recurring schedule and you change the temperature of one day of the schedule, all of the recurring days will adjust. If you change the time, however, all of the recurring events will consider that a new different event and won’t adjust). I love the graphs within the app, which help me understand usage at different time. I also like the humidity tracking feature, though I don’t know how accurate it is.
