    • A Simple, Reliable Thermostat Without the Gimmicks
Color: White
Installed it a few days ago and it’s been solid. I’ve avoided Wi-Fi thermostats for years, but this one felt worth trying. It’s not a “smart” or “learning” model, which is exactly what I wanted. Once it’s online, you set a schedule and it just runs. Setup was straightforward. The app walks you through it step by step. You do need a basic sense of your HVAC wiring, but nothing complicated. It looks good on the wall and the included backer plate covered the old screw holes. Getting it onto my Wi-Fi took a couple attempts, but that was my firewall, not the thermostat. Once I fixed the network rules, it connected without any issues. The app itself is simple to use. I also added it to Apple Home with the Matter QR code, which gives you the basics inside Apple’s interface. The advanced controls are a nice bonus. You can fine-tune how stages 1, 2, and aux heat behave, and you can set a temperature cutoff for the heat pump. The defaults are fine, but it’s great to have the extra control if you want it. Overall, I’m happy with it. No learning features, no surprises — I set the temps I want and let it run. ... show more

    • Seamless Integration with Home Assistant and Meross Ecosystem! Perfect Thermostat for Any Home!
Color: White
Installed the Meross Smart Thermostat earlier this week, and setup was incredibly easy and it connected to Home Assistant very easily and integrated perfectly with my Meross smart light switches in their app. The design is clean and modern, temperature control is accurate, and the app makes scheduling simple. It responds instantly to adjustments from my phone or voice commands, and everything just works seamlessly together. For the price, it’s an excellent smart thermostat that fits right into an existing Meross ecosystem or really any matter comparable ecosystem! ... show more

    • Easy Setup, Customizable, and Works Perfectly with Smart Home
Color: White
Review Image by SnailExploder SnailExploder
Super easy to install and set up! The Meross Smart Thermostat works great right out of the box and is very customizable, which makes it simple to fine-tune to my home’s needs. The app can house multiple Meross devices, scheduling is a breeze, and it integrates well with smart home systems. I love that you can set it to auto so you don’t have to choose only heat or cool as well. Makes life much more convenient in the spring and fall. The only downsides are that the fan can only be set to recirculate for a period time per hour instead of saying that you want to run the fan for 10 min every half hour but that is more just my preference. Also, there’s no built-in geofencing. However, I was able to work around the geofencing by using Apple Home automations, so it’s not a big issue. Overall, an excellent thermostat for the price — easy, smart, and reliable! ... show more

    • Better temp control than Nest
Color: Black
As easy to install as a thermostat can be. I like that it Integrates all the major platforms, plus has its own surprisingly good app. For me the top feature is Home Assistant integration. I replaced a very new Nest learning thermostat with this one and am thrilled with the change. The Nest wasn’t nearly as good at keeping a constant comfortable temperature - my house was too cold 1/3rd of the time, just right 1/3rd of the time, and too hot 1/3rd of the time. I tried everything to work around this (even installed smart vents, which helped) and eventually gave it up on it. The Meross has good defaults and I see exactly where I could adjust this if I wanted to. Biggest negative I can think of is the screen is a little less fancy, but it looks exactly like it does in the pictures on Amazon, so this shouldn’t be a surprise to anyone. It’s a functional, straightforward look and I’ve grown to like it. ... show more

    • Has all the bells and whistles you see on a Ecobee / Nest

This is a good basic smart thermostat. What I like: 1) It has Matter. Easy to integrate into Homekit and Home Assistant 2) Gives you multiple schedules to enable by day and time. 3) I like the Meross app. It has a good design and is easy to adjust the temperature. 4) it has a usage dashboard that displays the time the system was on heating and cooling. I'm a bit of a data junky so I like seeing the amount of time the system is on. You can use the date to predict your heating and cooling cost for the month. 5) I like the added backplate bezzel. Looks good and covers some of the imprefections (like the screw holes from my prior thermostat). What I didn't like that much: 1) installing was easy but the back plate where the wires are routed are small. It was a bit troublesome but not a deal breaker. 2) The display is basic but easy to navigate, I just wish it could be brighter. I changed the settings to the brightest settings on active and standby but I think brighter would be better. Overall, it's a good purchase and I'll be keeping it. ... show more
