Modern heating systems require precise control, and a digital thermostat is becoming an indispensable assistant in this process. Model ME81H from the company Beca It has gained popularity thanks to its reliability, stylish design, and ability to integrate with smart home systems. Connecting the device to a wireless network opens up extensive remote climate control options from anywhere in the world.
The initial setup process may seem complicated at first glance if you're unfamiliar with the specifics of the data transfer protocol. Unlike simpler controllers, this controller requires strict adherence to a specific sequence of steps to successfully synchronize with the router. Critical: The device only supports 2.4 GHz WiFi frequency; 5 GHz networks are invisible to it. Understanding this technical nuance will eliminate most problems at the start.
In this guide, we'll cover every step in detail: from preparing the equipment to fine-tuning the operating scenarios. You'll learn how to properly reset the settings if something goes wrong and how to ensure a stable connection for comfortable use of the device. Proper installation is the key to long-lasting and trouble-free operation of your heating system.
Equipment preparation and network requirements
Before starting the active setup phase, you must ensure that all system components are ready for operation. Thermostat ME81H This is a smart device that requires a stable power source and a high-quality signal. If you've just finished mounting the equipment in a wall or on a DIN rail, check the connections for reliability and the presence of voltage at the terminals.
Particular attention should be paid to the parameters of your home network. As already mentioned, the router must broadcast a network standard 802.11 b/g/n at 2.4 GHz. Many modern dual-band routers combine 2.4 and 5 GHz networks under a single name (Smart Connect), which sometimes causes conflicts when connecting older or specialized IoT devices.
β οΈ Note: If your router uses the Smart Connect feature, try temporarily separating the networks by giving them different names (for example, Home_24 and Home_5), or force your mobile device to switch to 2.4 GHz before starting the setup.
You'll also need a smartphone running Android or iOS. Make sure your phone's GPS and Bluetooth are enabled, as modern smart home apps use these features to locate the device on the local network. Without GPS enabled, the search process may simply fail.
For ease of monitoring, prepare a table with the main characteristics of the device so that you can check them during operation:

| WiFi frequency | 2.4 GHz (802.11 b/g/n) |
| Supply voltage | AC 95-240V or DC 12-24V |
| Max. load current | 16A (resistive load) |
| Platform | Tuya Smart / eWeLink / Smart Life |
Installation and basic configuration of the application
The foundation of your climate control system will be a mobile app. Although the thermostat ME81H It can operate autonomously, and its full potential is revealed via a smartphone. Depending on the specific firmware version, the device may be supported by different platforms, but the most universal and frequently used is Tuya Smart or Smart Life.
Download the app from the official app store (Google Play or App Store). After installation, register a new account using your email address. Don't ignore the email or SMS confirmationβthis is necessary to restore access if you change your device or forget your password.
When you first sign in, the app will request permission to access your location and local network. These requests must not be ignored, otherwise the app will not be able to detect the thermostat in the list of available devices. After authorization, click the "Add New Device" button, typically indicated by a plus symbol in the upper corner of the screen.
βοΈ Check before adding
From the category list, select "Small Appliances" or "Climate Control," or use automatic scanning. The system will prompt you to select the adding mode: "EZ Mode" or "Hotspot Mode." ME81H Quick connect mode is most often recommended, but if it fails, access point mode works without fail.
The process of pairing a thermostat with a router
Now we move on to the most crucial stepβconnecting the controller to the internet. Turn on the thermostat if it's not already active. The screen should display the current temperature or standby status. To enter pairing mode, press and hold the power button or the dedicated WiFi button (marked with a signal icon) for 5-7 seconds.
The WiFi indicator on the screen will begin flashing rapidly, indicating the device is entering configuration mode. At this point, the thermostat will create its own network or become visible for scanning. Open the app on your smartphone and enter the password for your WiFi network. Make sure to enter the password correctly, maintaining the correct capitalization.
After clicking "Next," the data transfer process will begin. The smartphone will send the SSID and password to the thermostat. During this process, the phone's screen may temporarily go dark or switch colorsβthis is normal protocol operation. Keep the app open and keep the phone no more than 1-2 meters away from the device.
β οΈ Note: If the thermostat's indicator light stops flashing and remains solid, the connection attempt has been interrupted. Reset the WiFi settings (while holding the button) and repeat the process, ensuring your phone is connected to the 2.4 GHz band.
A successful connection will be confirmed by a change in the indicator's blinking pattern: it will either blink slowly (every 2-3 seconds) or remain solid, and a success message will appear in the app. You can now name the device, such as "Living Room Thermostat," for easy management.
Setting up operating modes and schedules
Once successfully integrated into the network, flexible control options are available. The app interface allows you to set not only the target temperature but also complex operating scenarios. You can switch between "Comfort," "Eco," and "Freeze Protection" modes directly from your smartphone screen.
One of the most useful features is the scheduling feature. Thermostat ME81H Allows you to set different temperature profiles for each day of the week or groups of days (weekdays/weekends). This significantly saves energy by reducing heating when no one is home and warming the room up when you arrive.
To set up a schedule, go to the corresponding section of the menu. You'll need to specify the time intervals and the desired temperature for each. For example, you could set the economy mode (16Β°C) from 8:00 AM to 5:00 PM, and raise the temperature to a comfortable 22Β°C by 6:00 PM.
Don't forget about the "Open Window" feature. When enabled, the thermostat will monitor for sudden temperature drops. If the sensor detects a rapid cooling (typical of ventilation), it will temporarily turn off the heating to avoid heating the outside air, and turn it back on when the temperature stabilizes.
The secret to energy saving
Set the hysteresis (the difference between the on/off temperatures) to the minimum value (0.5Β°C) if you have electric underfloor heating, and to a higher value (2-3Β°C) if you have radiator heating with a high inertia. This will prolong the life of the actuators.
Integration with voice assistants and ecosystems
A modern smart home is unthinkable without voice control. Thermostat ME81H gets along great with popular assistants like Amazon Alexa, Google Assistant And Yandex Alice (via the Tuya Smart skill). This allows you to control your climate control without taking your phone out of your pocket.
To activate this feature, find the "Other connection methods" or "Voice control" section in the app. Select the desired assistant and follow the authorization instructions. You will need to log in to your Tuya/Smart Life account to link the devices.
Once paired, you'll be able to issue commands like, "Alice, turn on the heating" or "Ok Google, set the temperature to 23 degrees Celsius." You can also add the device to automation scenarios. For example, when you leave the house (geofencing), the temperature will automatically decrease, and when you return, it will increase.
It's important to note that voice commands require a stable internet connection not only on the thermostat but also on the intermediary device (speaker or phone). Local control via the app is possible even without internet access (within a LAN), but voice functions and remote access will not work without a global network.
Diagnosing problems and troubleshooting errors
Even with a perfect setup, glitches can occur. The most common issue is connection loss. If the WiFi indicator turns red or the device shows as "Offline" in the app, check the signal strength at the installation location. Thick walls or metal floor heating screens can block the signal.
Another common issue is time desynchronization. The thermostat retrieves the correct time from the network each time it connects. If you see an incorrect time, check the time zone settings in the app or try reconnecting the device to the network.
If your device is frozen and unresponsive, perform a hard reset. This is usually accomplished by pressing and holding the power button for more than 10 seconds until the logo appears or the screen goes completely dark. After the reset, the network settings will be reset, and you'll need to reconnect.
β οΈ Note: If you experience frequent connection drops, try changing the WiFi channel on your router. Crowded channels (1, 6, 11) can cause interference. Use WiFi analyzer apps to select a clear frequency.
It's also worth checking the power supply voltage. If the thermostat operates on a 220V power supply, make sure the phase and neutral wires are connected correctly. Unstable power supply voltage can cause the controller to periodically reboot.
Is it possible to control a thermostat without the internet?
Yes, basic controls (temperature adjustments, on/off) are available locally via the buttons on the device itself, even without internet access. However, remote control via the app and voice commands will not work.
Is ME81H compatible with dual circuit boilers?
The ME81H model is a single-circuit thermostat. Controlling dual-circuit systems (heating and hot water) requires more complex models with two independent outputs or the use of an additional relay.
What should I do if the app doesn't detect the device?
Make sure your phone and thermostat are on the same 2.4 GHz network. Try using AP (Hotspot) connection mode by temporarily disabling your phone's mobile data. Also, check if your antivirus or firewall is blocking local connections.
How do I reset my thermostat to factory settings?
A hard reset (Factory Reset) usually requires turning off the device, holding down two buttons (often Up and Down or Power and Menu), and turning on the power while holding the buttons for 5-10 seconds.
