Great Smart Baseboard Heater Thermostat!
Meross Smart Baseboard Thermostat with HomeKit.The Meross Smart Baseboard Thermostat is stylish and easy to install. While not emphasized enough in their paper directions the Meross app contains an excellent video which describes the installation process nicely. Be sure to download the app and begin the process of adding the MTS 200 thermostat to the app and the link for the video will be made available on the third page of the setup process. Be sure to watch it prior to any physical installation of the device. The only small element the video neglected was informing the user that the wall plate of the thermostat must be installed in the upright position as indicated by the text on the front of the wall plate itself so that the faceplate set screw points toward the floor. Following the app directions installing the thermostat in the Meross app (which connects directly to HomeKit in Apple) is straightforward. I was unable to connect on the first attempt; however, I reset the thermostat (by holding the up-and-down arrows simultaneously on the thermostat) and the second attempt worked flawlessly. For nearly the same price the Meross Smart Baseboard Thermostat is a much better value than a standard, manual seven day programmable thermostat due to its increased functionality. Multiple set points and times can be programmed as well as having more advanced features such as programable switching differential (the plus or minus temperature fluctuation before starting and stopping the heater) or having the thermostat turn off should there be a chill in the room from an open door or window. In addition, the thermostat monitors energy use providing a graph of energy consumption. While I have not used the thermostat during the heating season I believe it to be an excellent value for its functionality as well as its ease of instillation and use.Addendum to original review: now that the heating season has started, I can see that the thermostat does an excellent job of keeping the room at the required temperature. I can control the high and low range and I’m able to easily see the current temperature of the room on the unit. As mentioned before this is an excellent product and works well after installation.

Great Product and very helpful support team
Great Thermostat. I was looking at Mysa and decided to buy this one first – after using it for a few months I bought 5 more – so I now have a total of 6 thermostats in my house to control the electrical baseboards. I was tired of mechanical ones as they break down so easily.The installation was bit annoying at first. Since I have the same SSID for WIFI for both 5Ghz and 2.4 GHz and this devices only connects to 2.4Ghz, it wouldn’t join the wifi and I had to try it a few times. Then I was able to configure my WiFI to turn off the 5GHz band and then do the installation of these devices. The moment I shut off 5Ghz, it worked like a charm. However, 1 device out of 6 refused to configure – don’t know what the problem was. So I contact Meross support via email and they promptly emailed a replacement device to me. The replacement device worked like charm.Right now I have 6 MTS200s in my house and they are reporting not just temperature but also humidity from each location. The App/UI is great and easy to follow. I also have some IFTTT rules with which I automate the settings via the HomeKit.Programming is easy in the meross app and I also have it liked to Apple HomeKit .. all working wellVery happy with the performance and reliability so far and a great support team for promptly replacing the one bad unit.

Good looking, functional and reliable thermostat
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.

Look and work great. Can’t beat the rice
Ordered 3 to use on baseboard heat in vacation home. Installed one and it functioned fine as a basic thermostat but could not get the smart features to work. Contacted customer service and they sent me another to try and it worked perfectly. I initially gave a poor review but after customer service follow-up I gave them 4 star rating. Thermostat looks and works great and is lower priced than comparable brands

Il termostato funziona molto bene e l’installazione è risultata davvero semplice. Ho solo dovuto portare fase e neutro nella scatola, poiché il modello precedente era alimentato a pile. Ho acquistato anche un adattatore da placca 503 a 502, che ha reso il risultato finale pulito ed esteticamente gradevole.Il dispositivo è intuitivo sia in modalità manuale sia in modalità Smart. L’ho integrato nell’ecosistema Apple HomeKit e la compatibilità è perfetta. Anche dal punto di vista estetico è molto curato e l’interfaccia risulta chiara e immediata.Nel complesso, un ottimo prodotto.

Temp schommeling dus 0,5 naar beneden en 0,5 naar boven dus eigenlijk op 1 graad nauwkeurig.Werkt prima met de app.Temperatuur per dag plannen is omslachtig.ALLEEN kinderslot is te omzeilen op de fysieke thermostaat!

Super easy to install and setup, working as expected. Built in schedule is useful to save costs with off peak heating and not heat up on weekends (home office). You can also automate and control remotely via HomeKit. The app also shows costs and heating history. You can choose where to measure the temperature from: air or probe.

Does not support underfloor heating as claimed in the title and description.

Hola, he estado probando bien todo antes de hacer la reseña y aquí dejo mi opinión:Viene con todo, instrucciones que incluyen el español y en la caja el termostato muy bonito con su sensor cableado (opcional), y los tornillos porque he de decir que este termostato es para empotrar en una caja de registro o como en mi caso que tenía uno de superficie, yo le he puesto una caja de superficie y apenas sobresale del que tenía anteriormente.La instalación mas bien sencilla y antes recomiendo descargarte la aplicación meross y darle al + para añadir dispositivos y seleccionar MTS200 en mi caso caldera a gas, hay un video que te guía por todo el proceso.El termostato queda muy bien estéticamente y la mejora de pasar de un analógico a este es abismal.Tiene muchos ajustes, brillo, bloqueo para niños, programación, si detecta un bajón de temperatura se desconecta automáticamente (ventana abierta). Lo mejor es que se puede hacer todo desde la aplicación móvil, ya era hora de decidirme y dar el paso que era de lo poco que me faltaba por automatizar.Funciona muy bien, es sencillo de manejar y todo digital y encima se integra en mi Home Assistant.Compatible con Homekit.Que mas se puede pedir!!!
