⭐️⭐️⭐️⭐️⭐️ Amazing Smart Thermostat — Works Perfectly with HomeKit!
I’m really impressed with the Meross Smart Thermostat (MTS300). Installation was super easy — the wiring guide and app made setup simple, and I had it running in about 20 minutes.It connected to Apple HomeKit instantly and works perfectly with Siri. I can adjust the temperature from my iPhone or Apple Watch, and it responds right away. The app interface is clean and intuitive, and the thermostat looks sleek and modern on the wall.Temperature control is accurate and consistent — no big swings or lag. I also love how it integrates with HomeKit automations (like adjusting temp when I leave home).Overall, this thermostat is easy to install, reliable, and ideal for Apple users. Highly recommended!

Google bricked my Nest, so I switched and I’m glad I did
Google decided to stop allowing my Nest thermostat to work, and I wasn’t about to give my hard earned money to a company that would screw customers and brick a perfectly functional device.I’ve had good luck with Meross products in the past, including a garage door smart adapter that I love and have taken with me from home to home without any issues. So when I started looking for a replacement thermostat, I decided to give this one a try.For reference, I have an air conditioner with a heat pump and a resistive electric furnace for backup. Since it’s cold where I am right now, I haven’t needed to run the A/C for any length of time yet, but I did test it briefly just to confirm compatibility. It switched between cooling, heat pump, and emergency heat modes without any issues at all.Installation was straightforward and the instructions were surprisingly helpful, as was the setup in the app. Just make sure you have a C-wire. The software is smooth and much easier to navigate than Google’s ever was. It just connected to the WiFi and started working.The Meross app is well designed. You can do everything my Nest could do and more, and I didn’t notice any lag at all. It just works exactly how you’d expect. It also integrates perfectly with my Amazon Alexa smart home setup and my Google Home devices, so I can change the temperature or mode using only my voice whether I’m home or away.I’m really happy with how this thermostat performs, especially for a fraction of the price of what I originally paid for my Nest, which now sits as a brick thanks to Google’s greed.So if you’re fed up with anti consumer actions from the likes of Google, and want a reliable, straightforward, and well built smart thermostat that simply works, give this one a try. I highly recommend it.

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 Assistant2) 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.

​I am absolutely thrilled with my purchase of the Meross Smart Thermostat. From installation to daily use, this device has exceeded all my expectations, making it one of the best smart home upgrades I’ve made this year.​Effortless Installation & Setup:The process of setting up the Meross was incredibly straightforward. The instructions were clear, and I had the old thermostat swapped out and the Meross unit installed in under 20 minutes. Connecting it to my home Wi-Fi and the Meross app was quick and painless.​Simple and Effective Operation:The physical design is sleek and modern, and the interface is intuitive to use right on the wall. However, the real magic is in the app. Being able to effortlessly set schedules, adjust the temperature remotely, or just check the current status from anywhere is a game-changer. The thermostat is highly accurate and maintains the set temperature perfectly.​Reliability is Key:I’ve been using this for several weeks now, and I haven’t experienced a single glitch, drop in connectivity, or scheduling error. It just works—easily and effectively—every single time.​If you are looking for a reliable, easy-to-use smart thermostat that provides excellent value without unnecessary complications, look no further. Highly, highly recommend the Meross!

Works great and was super easy to install. Install the app before and it will explain exactly how you can install. Setup took less than 30 minutes, and it connected to Wi-Fi and my smart home system with no issues. The design looks modern, and the app makes it simple to adjust or schedule temperatures. Definitely recommend if you want a reliable, affordable smart thermostat.

Context & 1-Month UpdateI’ve been running this thermostat for over a month now. I originally bought it because I refused to pay a monthly subscription just to use full features on a device I own.Update: After 30 days, it has been rock solid. No Wi-Fi drops, no missed schedules. But the real value is how it integrates with a wider smart home. Local LAN control, if you use Home Assistant (HA), is also very easy via the Meross LAN integration. This means you don’t have to dependent on their cloud and you can control this thermostat locally. If the Meross cloud servers go down (or my internet cuts out), my automations still run perfectly because the control is local to my network. Remote Access: Because I run HA, I can control my heat from anywhere in the world either with Home Assistant or Meross app.Advanced Automation (Virtual Zoning)The Problem: Big brands (like Ecobee) want you to buy expensive proprietary sensors to balance the temperature in different rooms (e.g., a cold bedroom vs. a warm hallway). Since Meross integrates so well into HA, I set up “Stratified Controls.” I use cheap Zigbee temperature sensors from AliExpress) in different parts of my house to where I can have the thermostat run at a high temp until the zone I want gets to the target temperature. For example, after 10pm if my bedroom < 20°C, turn on Meross Thermostat." The thermostat acts as the engine, but the cheap sensor acts as the brain. I get multi-room climate control for a fraction of the cost of a closed ecosystem but after 8am I just use the temperature on the main floor since people are generally downstairs.The "Planned Obsolescence" FactorA friend of mine is currently being forced to replace his expensive Google Nest setup because they are retiring support for older APIs and hardware. Because the Meross works with standard protocols (HomeKit/Matter/LAN), it is much harder for the manufacturer to "brick" it remotely. That gives me more peace of mind.Installation RecapMy older home didn't have a C-Wire. The seperate c-wire adapter worked perfectly and took about 10 minutes to install at the furnace. I don't fan the loss of discrete fan control (one of the things you lose with this wire) a big deal.Bottom LineIf you just want a thermostat that works with Alexa/Siri, this is great. But if you are a "Power User" with Home Assistant, this is the best value on the market. It gives you the freedom to build complex climate rules (like virtual zoning) without locking you into a subscription or an expensive proprietary ecosystem.
