@gafich10 Hello gafich10,
Great to see your interest in automating your room temperature control with Aqara products! 
To achieve independent heating control in three rooms using your Aqara radiator thermostats and the Aqara T2 relay, you can set up a system where each thermostat regulates the temperature of its respective room, while the relay controls the boiler.
Here’s a simplified approach:
-
Radiator Thermostats Configuration: Each Aqara radiator thermostat can be installed in a different room. Ensure that each thermostat is properly calibrated and networked under the same hub to allow for seamless integration and control.
-
Boiler Control with T2 Relay: You can use the Aqara Dual Relay Module T2 to control the boiler. The relay can act as a thermostat switch for the boiler, turning it on or off based on the temperature requirements of each room. This setup allows the boiler to be activated only when at least one room requires heating.
-
Automation Setup: Using the Aqara Home app, create automation rules where each thermostat communicates its heating demand to the relay controlling the boiler. For example, if any thermostat detects that the room temperature is lower than the desired setpoint, the relay can trigger the boiler to start heating.
Remember, the key to success is ensuring all devices are properly networked and automation rules are correctly set up to reflect your heating preferences.
If you encounter any challenges, our community is here to help! Feel free to share your progress or ask for further assistance. 
Happy automating!
Note: Make sure to check the compatibility of your existing boiler with the Aqara T2 relay for optimal performance.

For more accurate temperature readings, you might want to network additional Aqara Temperature & Humidity Sensors with each thermostat. Ensure they are placed 2-3 meters from the thermostat and away from windows. -
Utilize the Aqara T2 Relay:
Connect the Aqara T2 Relay to your boiler’s control circuit. This relay will be responsible for turning the boiler on and off based on the thermostat readings. Make sure it’s set up in the ‘Wet Node Mode’ for controlling the boiler. -
Automation Settings:
You can create automations using the Aqara app to link each thermostat with the relay, ensuring the boiler adjusts its operation based on the demand from each room. This way, when a room reaches its desired temperature, the thermostat will signal the relay to manage the boiler accordingly. -
Fine-Tuning:
Ensure each room’s thermostat is set to its desired temperature, and test the system to ensure the relay responds as expected.
Remember, the key here is to ensure that each thermostat is independently controlling its corresponding relay, which in turn manages the boiler’s operation. This setup should give you the independent control you’re looking for.

@Zoeyy Hello Zoeyy,
It sounds like your TVR Aqara radiator thermostat is playing hard to get with your boiler signals! 
Let’s try to make sure everything is in harmony.
-
Valve Calibration: Make sure that your thermostats are correctly calibrated. The push rods of different valves have different strokes, so calibration is crucial. You can do this by pressing the thermostat button three times in quick succession or through the app. This ensures that the open/close stroke of the valve properly adapts to the thermostat, improving temperature control accuracy.
-
Temperature Sensor Placement: Ensure that your temperature sensors are placed optimally. The sensor should ideally be in the same room as the thermostat and within a 2-3 meter range. Avoid placing it near doors, windows, or any vents that might cause inaccurate readings.
-
Check for Valve and Installation Issues: Sometimes, the problem might be due to a malfunctioning valve or incorrect installation. In such cases, checking the installation and considering a valve replacement could help.
-
Network Connection: Ensure that your thermostat is properly networked with the app to receive and relay accurate signals.
If you’ve tried these steps and the issue persists, it might be worth checking if there’s a need for a different setup or consulting a professional for a more tailored solution. Keep the questions coming—we’re here to help you achieve that perfect cozy home vibe!
