meross Smart Thermostat for Home, WiFi Thermostat Works with Matter, Alexa, Apple Home, Google Assistant, App & Voice Control, 7x24h Scheduling, Energy Saving, C-Wire Required

cheap but gives me really good control including full scheduling and “away mode” when nobody is home
I have now installed two of these in my home (I have two HVAC systems) and I am really pleased with them. The installation was pretty straightforward, definitely doable by anyone who is a little bit handy.See the full review for the features I was surprised to find and info on how to program this to switch to eco/energy saving mode automatically when nobody is home.I chose this unit because it is one of the first to support Matter out of the box. I have an Apple TV 4K, which acts as a Matter controller, so I can integrate it with Apple Home without a separate bridge device or anything like that. Matter is compatible with all the major smart home platforms, so I am not locked into a vendor-specific system. The Meross app is required to do much of the initial setup, but once I got everything set up I can control it from the Home app and automations without using the Meross app or widgets at all.First, here are a few features it includes that are hard to confirm in advance:* You can calibrate the temperature and humidity sensor. This is important because both units were way off out of the box (3 or 4 degrees off and about 6% humidity). I set a dedicated sensor right on top of the thermostat, let it sit for a while to stabilize, then went into the Meross app and adjusted the calibration until they matched.* You can adjust the “threshold” settings. With my old thermostat, the HVAC cycled way too often. With the Meross I tell it to let the temperature drift a full 2° before kicking the system on, which means it runs longer and rests longer, which is better for the longevity of the system.* You can also adjust settings like making sure the A/C compressor doesn’t turn on for at least a few minutes after the last time it was running, etc. I have it set to run the fan for 30s after stopping the heating/cooling to capture the residual heat/cool from the system, and that is adjustable, too.* You can set the fan to run at least every hour just for circulation. So you can say that the fan should run at least 5 minutes every hour, for example, just to make sure the air in the house is circulating. If the fan is already running 5 minutes because of heating or cooling, the setting does not increase fan time, it only affects when the fan would not be running otherwise.* It can monitor filter usage by calendar weeks/months or by time actually running. My filters last longer in the spring and fall than they do in the summer and winter. This setting lets you track the actual usage instead of just the simplistic “time since last change”.One of the main features I wanted was the ability to detect when nobody is home and switch to a lower-energy state. This isn’t supported directly, but I was able to make it work using Apple Home and its automations. Note: this works using Apple’s location tracking (the same thing that drives the FindMy app), which is a lot more reliable than a motion sensor. Here’s how I set it up:* I created an Apple Home “Scene” for each setting that I want. In my case I just have “Sleeping”, “Awake”, and “Nobody Home”, each of which controls the device and sets it to a target temperature. None of my actions change the thermostat directly, they just invoke these scenes. This means that in winter when I switch to heating I can just update what each scene does and all the actions will do the right thing.* In the Home app I went to the “Automations” tab and create a series of actions. This was the most complicated part. I have 3 different kinds of actions:1. At a given time, if somebody is home run a scene. For example, at 7:00 AM if somebody is home run the “Awake” scene (which sets the target temp). Ditto for evening (set to sleeping). This emulates a basic schedule, but the transitions only happen if at least one person is home.2. When the first person arrives home and the time is in a certain range run a scene. For example, when the first person arrives home (the house was empty and then a family member arrived) and it is between 7:00 AM and 10:00 PM invoke the “Awake” scene, which triggers the target temp. I have one from Midnight to 7:00 AM (Sleeping scene), 7:00 AM to 10:00 PM (Awake scene), and 10:00 PM to midnight (Sleep scene). Night has to be chopped into two intervals. This switches away from my eco setting to normal when somebody arrives at home.3. To “Nobody Home” when the last person leaves. When the last person leaves the house, switch to the energy saving setting. Since the other transitions only happen when somebody arrives home or somebody was already home, this setting “sticks” for as long as nobody is home.* I don’t set or enable any normal “schedule” feature (notably I do not use the schedule feature of the Meross app) since they are not flexible enough to consider people coming and going, but have everything fully scheduled.Another feature I am interested in but have not tried yet is the ability to add another temperature sensor. For me, I want one in my bedroom so I can tell the system that the temperature in my bedroom is what matters at night, not the temperature where the thermostat is installed. It has this support, but you have to buy a Meross sensor and it has to have a special hub. I wish it was a cheaper device and didn’t require a hub, but at least it exists.So overall I am really happy with this smart thermostat. It’s one of the cheapest out there but integrates really well with Apple Home and gives me all of the control and features that I want. It took a little playing around to figure out how to do the “away mode” detection (the Matter protocol is pretty limited, which is why the scene/automation setup is necessary), but I’m happy with the results.

This little guy really exceeded my expectations. It offers a right balance between functions and cost. I always want a Wi-Fi thermostat that I can control temperature with my phone, especially in those cold early mornings without leaving bed or when you don’t want to go downstairs to press the button. But I don’t want to pay couple hundred dollars for that. I had good experience with Meross garage door opener, so I want to give this a try. The installation is super easy, it took me 15 mins to replace my old thermostat. I only use it for the furnace to control heat, but it works with different kinds of setups to control both heat and cooling. I like the sleek and simple design, and you can turn off other icons and only show the temperature. The app is plain vanilla and has all the necessary functions, even usage monitoring, and it’s matter compatible so I can use either the app or Alexa to control it. Overall I’m very satisfied with it, I think this is the best option in this price range.

I’ve been using the Meross Smart Thermostat for a few days now and I’m very happy with it. Installation was straightforward — I needed to use the included C-wire adaptor, and it only took about ten minutes to remap the wires following the instructions. The guide was clear and easy to follow, and having a built-in level on the backing plate made aligning the thermostat simple.Setup and pairing were equally smooth. Meross offers integration with Apple HomeKit, Alexa, and Google Home, and connecting to each was quick and hassle-free. I also really appreciate that it supports local control through the Meross LAN integration. This lets me control it directly from Home Assistant and connect it with my existing automations.One of the main reasons I went with this thermostat is that it doesn’t rely on a subscription or any kind of premium service to access its full functionality. Everything works out of the box without ongoing costs.Overall, I’m very happy with the Meross Smart Thermostat. It’s easy to install, reliable, and integrates well with a variety of platforms. Highly recommended for anyone who wants a smart thermostat without subscription lock-ins.

An excellent durable product, the folks at Meross really put a lot of thought into the product (This can be configured for a conventional furnace or a heat pump). It has a very nice minimalist design with an included back-plate to cover a electrical box if required. The wiring harness with pushpin friction connectors for the wires has a built in level, making the physical installation a breeze. The included documentation will make the install easy and the software guide from the application makes it even easier with clear directions, that breaks the down the steps into very small bites. Configuring the thermostat is really easy as well, with an innovative design that includes; a schedule that can be broken down into 15 minute increments with a seven programmable days, you can add additional temperature sensors to balance home temp, link it with google/amazon, usage logs with the option to add bill calculation based on usage and a furnace filter reminder.It only lacks an “occupancy/away from home” feature, you can manually lock the temp but lacks the geofence option of the Honeywell T10. However, if the folks at Meross can add that feature… this product will indicate the end of overpriced thermostats.My only complaint is screw length for mounting the wiring harness, they are too short if you are mounting this to a stud behind drywall. Otherwise it is a must buy for any homeowner who doesn’t care about a geofence feature.
