Looks great and works even better
If you have baseboard heating in your home, you already know that there are very few choices for thermostats. The ones that are widely available tend to look dated and aren’t aways very accurate. A few are programmable, but not in any way that is comparable to thermostats designed for the modern smart home. Until now. meross has designed a thermostat for baseboard heaters that looks great and offers all the sophisticated control and programmability that users would expect in a smart home thermostat.Be aware that meross makes two different thermostats that look identical. The MTS200 is designed for Apple Home (HomeKit). The MTS215, the model I am reviewing, is designed for Matter. It works with Apple Home, as well as with other smart home ecosystems.I didn’t test the model designed for Apple Home so I don’t know if it offers more functionality inside of the Home app than this Matter version. I can say that the MTS215 offers minimal functionality within the Home App. You can turn the thermostat on and off, manually adjust the temperature, and view a reading of the current room temperature. That’s it. The real benefit of Apple Home compatibility is not control but the ability to include the MTS215 in automations involving other devices. In contrast, the meross app offers sophisticated control of temperature, daily schedules, various presets and hold times, thermostat precision, temperature offsets, and more, all in an easy to use interface. It’s intuitive and works well.I’ve installed nine of these in my home, and I’m happy to say that the MTS215 has turned having baseboard heat into an advantage. For example, I have an exercise room that is only used for a couple hours a day. I’ve set up the thermostat to keep it at 59° 24/7. When I want to use it, I can select one of the temperature presets that I have set to 68°. The thermostat will heat the room to 68° for an hour before allowing the temperature to fall back to 59°. Simple. (The hold time is customizeable.) I trigger this preset manually because I exercise at a different time each day. The heating schedule for the rest of the house is fully automated. My home office is set up to only be heated during working hours. Otherwise it stays at 59°. The family room only gets heated during the evening hours when it will be used. Easy. These schedules, which are different for each room, lower my heating bill by only heating the rooms when I’m going to be in them. Yet adjusting or overriding the schedule is fast and easy when my daily routine changes.Aside from the functional benefits of the MTS215, this thermostat definitely brings an elevated look to a room. The large white-on-white display looks excellent on the wall. I’m particular about the aesthetics of my home so I am happy that my thermostats have gone from being a negative to a positive in this regard. There are different brightness settings for when the thermostat being adjusted and when it is quietly doing its job. In either case, the room temperature is easy to read from anywhere in the room.There are a few things to keep in mind in regard to installation. First, the maximum load each thermostat can handle at 240V is 3840W. You’re not likely to have a single baseboard heater that comes close to requiring this much power, but if you control two heaters with a single thermostat then this can be a problem. I have a room with two 2000W Cadet heaters. Together, they draw too much power for this thermostat. I’m stuck with a less sophisticated thermostat in that room.Second, this thermostat requires a neutral wire. My previous thermostat did not. The previous thermostat only required line and load wires and I didn’t have to know which is which. When installing the MTS215, I had determine which wire was line, which was load, and I had to pull the bundle of neutral wires out of the back of the junction box and connect to those as well. If you have a really old house, you might not even have neutral wires. That is something to check before ordering. My house is 30 years old and has them.Third, it can be easy to bend the eight pins that connect the front half of the thermostat to the back half. This isn’t an issue when separating the two halves. Just be careful when putting them back together. Don’t force anything. If they do get bent, you can use a small screwdriver or similar to gently bend them back.Installing these thermostats is not hard but you do have to have some basic knowledge of household wiring. YouTube, ChatGPT, and common sense can help you through the learning process. If you’re not sure, hire an electrician. The most important thing is to be meticulous and deliberate about keeping the power shut off while working with the wiring. Touching a live 120V wire gives you an uncomfortable tingle. Touching a live 240V wire is much more serious. It’s unlikely that you would break this thermostat by connecting it wrong. In a few rooms I had to rely on trial and error to figure out which wire was line and which was load. But you can definitely break yourself if you forget to turn off the power.The bottom line is that I can’t recommend this thermostat enough. It wasn’t inexpensive to swap out nine thermostats but I wouldn’t hesitate to do it again. I do wish the MTS215 was designed to handle just a little more power, but for most configurations it will be fine. It looks great. It works great. All nine of my units have been rock solid and completely glitch free to this point. (I can’t speak to long-term reliability yet but they come with a 2 year warranty.) Five stars.

PERFECT SMART THERMOSTAT! Work on Alexa!!
First of all I want to say these are well designed units & set up easily.I have old style 220v baseboard heaters with knob thermostat controls. The baseboard heaters never wear out but old thermostats needed replaced. I chose 2 brands (Mysa & Meross) to try. The Meross Models were my favorite mainly because of the App and the MTS215 was smaller & looked great on my wall!Review:MTS215 Setup: This was super easy & connected to my WiFi with no problems. Alexa added automatically to my Alexa Home system and the Meross App was amazing! I have seen where others have connected directly to the heaters but I suggest to place up the wall & bit away from the baseboard. Get a knowledgeable person to do this wiring.Operation: I have no issues with all my units. Flawless! The Meross App is where the magic happens with these smart WiFi thermostats. The App allows temperature display calibration (offset) adjustments which makes it possible to match all temperature settings in your home. This is important when telling Alexa to set Heater Group to a specific temperature. Also the app has brightness control which is important if using in a bedroom. The power meter on the Meross App is a game changer. It lets you see in real time your baseboard energy use and calculates cost (kWh)each day.Conclusion:I would recommend a licensed electrician to install wiring because these units need to be set a few feet up the wall & away from the heater. But once correctly wired they work & look great! I plan on eventually buying Meross thermostats for all heaters in my home.

I have been using this product for about a week now and it greatly improved the comfort of my bedroom.It was easy to install and set up; there is also a compatibility tool on their website to help you identify if the thermostat will work for your case.It’s design is modern and there are lots of functionality that can be done in the app, like controlling the brightness of the screen in standby (when no clicks are being performed in the unit for some time) and active mode; You can schedule the temperature for specific periods of the day and specific days; check energy consumption/cost; child lock the screen;You can also preset 3 temperatures settings for comfort, sleep and economy that can be used if switching directly from the unit.I recommend it!

I really love this smart thermostat! It has a sleek, modern design and was super easy to install. Its compact size fits perfectly with my decor, and the display is clear and easy to read. The app makes programming a breeze — everything is straightforward and works smoothly. It’s made my home more comfortable while helping me save energy. Definitely a great upgrade from my old thermostat!
