    • Meross MTS300: A Seamless Blend of Style, Savings, and Smart Home Compatibility
Review Image by Adam Adam
Review Image by Adam Adam
The Meross MTS300 Smart Wi-Fi Thermostat has truly impressed me with its seamless integration and user-friendly design. As someone who values a smart home ecosystem, I was thrilled to discover its Matter compatibility, allowing it to work effortlessly with my Apple Home setup. It will also work with Amazon Alexa, Google Assistant, and SmartThings with zero issues. Installation was a breeze, taking less than 30 minutes with clear, app-guided instructions, and its sleek glass panel with touch controls adds a modern touch to my living space. The fact that it’s compatible with 95% of heating and cooling systems made it a perfect fit for my home, and I didn’t even need to worry about rewiring because it was a direct swap from my previous thermostat. One of the standout features for me is the energy-saving potential of the MTS300. The 7x24 hour smart scheduling lets me customize temperature settings for when I’m home or away, and I’ve already noticed a potential reduction in my energy bills—Meross claims up to 30% savings, and I’m inclined to believe it. The Meross app is intuitive, offering real-time energy usage tracking and remote control from anywhere, which is a game-changer when I’m running late or traveling. Even without Wi-Fi, the thermostat sticks to its programmed schedule, ensuring reliability no matter the circumstances. Beyond functionality, the MTS300 delivers on precision and convenience. The temperature accuracy of ±1°F keeps my home consistently comfortable, and the compact design (3.6 x 0.9 x 3.6 inches) blends seamlessly into my decor without feeling bulky. I also appreciate the thoughtful extras, like the trim plate to cover old wall marks and the built-in level for a perfect install. Priced at $99.99 (and even better at the $69.99 launch discount), this thermostat offers premium features at an accessible price point, making it a fantastic choice for anyone looking to upgrade their HVAC system with smart technology. ... show more

Review Image by Emmanuel Azeez Emmanuel Azeez
I recently added the Meross Smart Thermostat to my home, and it has been an excellent addition to my Apple HomeKit ecosystem. The setup was incredibly smooth, and it integrates seamlessly with my existing smart home devices. The responsiveness through Apple Home and Siri makes adjusting the temperature effortless, whether I’m at home or away. One of the standout features for me is the minimalist design. The thermostat has a clean, modern aesthetic that blends well with my home decor. The retro-style digital display adds a touch of nostalgia while still feeling contemporary and functional. The screen is crisp and easy to read, providing all the essential information without unnecessary clutter. Functionally, it performs as expected, maintaining a comfortable temperature with precise control. The scheduling options within the Meross app and HomeKit automation work flawlessly, ensuring my home is always at the perfect temperature without manual adjustments. If you’re looking for a reliable, stylish, and Apple-friendly smart thermostat, the Meross model is a fantastic choice. It’s an affordable alternative to higher-end options while still delivering excellent performance and seamless integration. ... show more

    • C-Wire Work-Around If No AC, Works With HomeKit
Existing wiring didn't have a dedicated C-wire, but found an easy fix if there’s no AC in your HVAC system. I had 4-wires going from furnace to thermostat. This furnace is in a shop so there's no AC. To create a C-wire, I took the Y-wire (which controls AC equipment) and connected it to the C terminal inside the furnace and on the Meross mounting bracket. Again, you're moving the Y-wire (mine was actually blue in color) to the C terminal on both ends. That gave me a proper C-wire BUT you need to tell the Meross app during setup that there's no Y-wire, and that there is a C-wire. So when the app asks you what wires you have, you simply input C, G, R, W. Doing this got the app to add the device properly (it does take a few minutes, just place phone near or leaning on top of the thermostat during this process, and be extra patient). The result is that in the app, the only options are HEAT and OFF (no AC, because it thinks there is none, and it's correct.) It’s best to add the device inside the Meross app first, then in the Apple Home app, if you're using an iPhone and HomeKit. The thermostat works well thus far and there are many setup and scheduling parameters in the Meross app. Having used a number of other Meross HomeKit devices, their app and build quality are better than most. Plus the price was very reasonable for a smart HomeKit compatible thermostat—during the Prime Spring Deal it was $69.99. Important to note, if you don't have a C-wire, and do have AC, Meross makes a “C Wire Adapter” kit for $25.99 that solves the lack of a C-wire issue (Meross Model MCA100). ... show more
