meross Smart Thermostat for Electric Baseboard and in-Wall Heaters Work with HomeKit, Alexa and Google Home, 120V-240V Wi-Fi Programmable Thermostat with Easy Install, Energy Saving, 4 Wires Needed

I have Cadet 240v baseboard heaters (about 5 years old) and the manual thermostats typically need major adjustments whenever it's extremely cold outside. The swing on them is fairly extreme so getting a consistent even temp is frustrating at times. I live where it can get to -25⁰F in the winter so the constant adjusting gets to be a hassle.I have multiple Meross products and have been looking at this thermostat for awhile now and I've been fortunate enough to join the Meross beta program. This will have no bearing on my review as I'm extremely critical of products I use.This isn't the best time of the year to install a new T-stat to try out as my days of needed heat are getting short but hopefully I'll get a few days of use from it.I know that these are for wall mounting but I have no easy way to do that without running new wires. So my plan was to install it where the old knob T-stat was directly on the heater. I did have to manufacture a mounting plate for it from a blank cover plate that was original to the heater. The installation process was very easy, it took me longer to make the mounting plate than it did to hook up the wires. Having it mounted near the floor, directly on the heater, seems to be working as it should.The T-stat is well designed and looks good. The display is straight forward and easy to read. In the app you can adjust the display brightness for when it's in operation and also in standby. Being familiar with Meross products I didn't have much use for the included manual. After powering it on and opening the app, adding it and finding my network was very easy. Fortunately I'm an Android phone user so getting it added was simple compared to reviews from Apple users.There are quite a few preferences that can be set in the app, swing, temp presets, temp calibration, and others. It is nice that in the app it gives you the humidity level. There are a plethora of Automation, Schedule, and Routine settings that can be programed, which I haven't yet gotten in to. So far I'm running it in manual mode. There are also presets which can be also be adjusted, Comfort, Sleep, and Economy, this is a nice feature. I noticed that in the app it also shows the outside temperature, I'm guessing it's getting this from my phone location, another nice feature.The only drawback with the display is not seeing what the T-stat is set at until you manually adjust it, it only shows the current room temperature. This is kind of a "minus" as it would be nice to glance at the display to see what it's set at versus having to open the app.I'll add again that it seems to be working as it should. This fall I'll have to update my review once cold weather arrives and heating season starts again.

My 30 year old house has electric baseboard heat, with a thermostat in each room, and some of the (original) honeywell thermostats have started going bad, either running the heat constantly or not at all, so I started looking for good replacements that also had smart home features - i.e. at a minimum an app that lets me control remotely from my android phone.After a bit of research, I narrowed my choices down to this Meross model and the Mysa Lite. Mysa seems to be a better known brand, but the Meross seemed very similar and the price point was a bit better. I also found a YouTube installation video by Meross that was well done and informative, so I decided on Meross and bought two thermostats.So far, this seems like a very good choice. The product was well packaged with a very brief (but well written) instruction booklet - but, as I said, more is available online if you need it. Since wiring has changed over the years, I had a bit of a hard time translating the conventions of the old thermostat to the new one, and it took a bit of trial and error to get the wiring right, but once I did everything else was smooth sailing. The thermostat lit up and the pairing and set up process was done intuitively through the smartphone app. The set up process was similar to other smart home apps that I've used from google, ring, kasa, etc.The thermostat looks VERY NICE on the wall. Certainly much better than the one it replaced. The display is bright but not overly so, and although the controls are minimal, you can set the temperature and cycle through hold/eco/pre-programmed settings. Many more settings are available on the app.I was also able with minimal effort to integrate the thermostat with google home, which is a plus since I have several other devices I control from there.The first two thermostats have been deployed for a couple of months now, and no complains, they do what I need reliably and intuitively. At some point down the road I'll be buying more to replace the rest of the aging thermostats.
