Review: Cost effective smart thermostat - I bought this to provide my aging oil boiler with smart features, this replaced the analog room stat which was easy to connect, changed the boiler to constant and now I have smart heating control and linking into Apple Home Kit. I have coupled this with Meross TRV's on a couple of the radiators which gives me much more control of my heating without having the expense of replacing the boiler to something more modern which would work with the likes of Hive or Nest. Simple and effective and I think a much cleaner look that the previously mentioned competitors. The app is basic but functional and easy to use to change schedules or manually control the heating. If you're looking to have remote access for your heating to have a warm house to come home to, this is a great option.
Review: A True Game-Changer for Home Heating: Seamless Smart Control and Fantastic Energy Savings! - I recently purchased the Meross Smart Thermostat (MTS215B) for my Combi Boiler to finally upgrade my home heating system from an old, mechanical thermostat, and I can confidently say this is one of the best smart home investments I've ever made. ​Unparalleled Compatibility with Matter. ​The primary reason I chose this model was its support for Matter, and the integration has been absolutely flawless. Now I know it would work in the event of an internet outage. It connected seamlessly with my existing smart home ecosystem (whether you use HomeKit, Home Assistant, Alexa, or Google Assistant, this thing just works). The Matter compatibility means setup is fast, and the response time for commands, whether through the Meross App or a voice assistant (I use both Google and Home Assistant) is instantaneous. The hubless design is another massive plus, keeping my setup clean and simple. ​If you’re replacing a standard wall thermostat, the physical installation is surprisingly straightforward. The unit fits perfectly into a standard UK back box, and the clear terminal markings made wiring easy. The setup guide in the Meross app is excellent and walks you through the initial configuration step-by-step. The unit itself has a modern, elegant, and flat aesthetic that looks fantastic on the wall. The display is clear and bright without being distracting. ​Smart Features and Efficiency ​The real value, though, is in the app and the intelligent features. The ability to set detailed heating schedules via the app is incredibly useful for ensuring the house is warm exactly when we need it, without wasting energy when we’re out. ​I especially appreciate the smart energy-saving functions: ​Open Window Detection: It automatically pauses heating if it senses a sudden drop in temperature, preventing wasted heat. Helpful if it's in a hallway for example and you need to leave the front door open for a while! ​Frost Protection: Peace of mind during colder months. ​Data Logging: Being able to see the temperature history and heating activity is vital for fine-tuning our schedules and optimizing energy use. ​This thermostat is highly accurate and has made a noticeable difference in how efficiently our combi boiler runs. It maintains a consistent, comfortable temperature without any of the fluctuations we experienced with the old unit. ​Final Verdict ​If you have a combi boiler or water underfloor heating system and are looking for a reliable, feature-rich, and universally compatible smart thermostat, look no further. The Meross MTS215B is affordable, easy to install, and delivers superior performance. Highly recommended for anyone looking to modernize their heating and save on energy bills!

## Questions & Answers

**Q: Is there a lock facility**
A: The touch panel is designed with a child lock to prevent children from mishandling it

**Q: Will this work with a Vokera gas combi boiler?**
A: It works for most condenser boilers. Mine is a Worcester Bosch, can’t imagine there’s anything special about yours that would prevent it from working. But, until you try you will never know. Just follow the installation instructions carefully.

**Q: Is it true that you can't set this to come on 3 times a day? Someone said they could only program 3 on and 2 off times! Thanks in advance.**
A: It can be set to come on 3 times and off 3 times on the schedule. Not sure if it can be set for more times through Alexa etc as not tried yet

**Q: Where one hub cannot cover the entire property can you have more than one hub**
A: Hi. Yes you can. I have one upstairs and one down. Hope that helps.

### ⭐⭐⭐⭐⭐ Easy to install, beautiful to look at
*by A***Z on 1 December 2025*

Not only does the Meross Smart Thermostat MTS215 look the part, but it was easy to install, and literally started controlling our underfloor heating before I had time to fix everything back on the wall! This is a sleek piece of equipment, designed for convenience and simplicity, with a great user experience and understated design that blends in with any decor. And since this is the Matter-compatible version, it pretty much connects to any smart device that can control Thermostats. So I can set our temperature, check the humidity levels in the room as well as switch the heating on when we're away and we have a house sitter staying over. Our previous 'dumb' thermostat required an advanced degree to set up and the house sitter could not switch the heating on, even standing there! With the Meross Thermostat, all that is a non-issue and the only non-smart part of the house is now covered. One small detail, the device is so sleek, that it is likely to be slightly smaller than what you had before, so I created a 3d-printed faceplate to hide the bits of missing plaster around the corners (see photos). Well done team Meross for building such a cool device! It's joined the rest of Meross devices in the house, which at Christmas times is important, since they control our street Christmas lights and other associated items :D
