Short description
Shelly BLU TRV is a smart thermostatic radiator head with Bluetooth and Zigbee connectivity, offering control over Wi-Fi using the BLU Gateway Gen3. It controls the temperature of a room by changing the flow of the hot water through the radiator. If needed, the temperature can be changed at any time by turning the Device rotating knob to the left or right, or through your mobile phone, tablet, or PC. The Device can also maintain the room temperature according to a set weekly schedule. It is powered by 2 AA, 1.5 V batteries.
External sensor support (compatible with Shelly BLU H&T, BLU H&T ZB, BLU H&T Display ZB, Shelly BLU Door/Window sensors, associated via BLU Gateway Gen3)
Integration with most smart home systems
Use cases
Remote temperature control: Make sure that your home is warm upon arrival and save energy by not heating the home unnecessarily when it is not occupied.
Smart scheduling for energy efficiency: Set up smart schedules in the cloud application to optimize your heating schedule and save on energy costs.
Boost mode for rapid heating: Activate Boost mode locally via the rotary encoder, or remotely through the cloud. This mode fully opens the valve to rapidly reach a comfortable temperature.
Room-by-room temperature control: Manage the temperature independently for each room. Achieve personalized comfort and improved energy efficiency by heating rooms according to their specific use.
Adaptive learning for personalized heating: Adjust your heating system for optimal comfort and safety using data from external sensors, such as Shelly BLU H&T and Shelly BLU Door/Window.

FAQ
When should I use the Underfloor heating functionality?
A1: When the Device is not mounted on a radiator but controls underfloor heating. A2: When the room is too large for the radiator to distribute and maintain heat evenly. A3: When there is poor air circulation around the radiator.
When should I not use Underfloor heating functionality?
A1: When the external sensor readings are not reliable. A2: When maintaining temperature is crucial.
Troubleshooting
Problem
Possible cause
Solution
The Shelly BLU TRV has lost its connection to the Zigbee coordinator.
The device has likely been unable to reach the Zigbee coordinator for an extended period.
When the network connection is lost, the BLU TRV automatically tries to reconnect following this schedule:
First 12 hours - retries every 60 minutes
Next 24 hours - retries every 6 hours
Next 7 days - retries every 24 hours
After that, retry attempts stop until the BLU TRV is rebooted
Select ZbE from the TRV menu using the BLU TRV display to initiate a reconnection
Reboot the Shelly BLU TRV to restart the automatic reconnection retry cycle
The Shelly BLU TRV displays significantly incorrect temperature readings compared to the actual room temperature.
The Shelly BLU TRV expects data from an external temperature sensor and doesn't revert to its default measurement.
Run the external temperature command without parameters: http:///rpc/blutrv.call?id=&method=Trv.SetExternalTemperature¶ms={"id":0}
Shelly BLU TRV is unresponsive during the firmware update.
The update does not complete successfully, causing the Device to enter Bootloader mode.
Perform a manual update using the Shelly Debug BLE Devices application:
We recommend using an Android smartphone for best results.
We recommend using new batteries for the update.
Before you begin, remove the Device from your smartphone’s Bluetooth settings by selecting Forget.
Open the Shelly Debug app.
Press and hold Reset button of the Device.
While holding the button, insert the new batteries and close the battery compartment. The Device will appear in the app’s Device list for about 40 seconds.
Select the Device from the list.
Start the OTA update.
The Device is paired to an external sensor. The Device shows a temperature above the target, but the valve remains open.
Underfloor Heating mode is not enabled. In this case, the Device might receive a higher temperature reading from the paired external sensor, which it uses to adjust (correct) its internal temperature measurement. Therefore, valve control is based on this corrected internal temperature rather than directly on the external sensor's reading.
This behavior is normal. Enable Underfloor Heating mode if you prefer the Device to rely exclusively on data from the external sensor, ignoring the built-in sensor.
The Device senses a quick drop in temperature and opens the valve early to keep the temperature from going below the target.
This behavior is normal and is part of the normal operation of the algorithm.
The radiator heats unevenly, causing the Device's temperature to be lower than expected.
Ensure proper water flow in the radiator by bleeding it.
Underfloor heating is enabled, but the device is not receiving updated temperature values. The gateway might be too far away, preventing the Device from receiving the latest external temperature reading.
Move the gateway closer to the Device to improve communication.
The temperature increases when the algorithm is changed via the power_save flag.
Applicable for FW version ≥1.2.0
The BLU TRV adjusts its current temperature reading based on radiator heat. Changing the algorithm or updating the firmware might reset these adjustments. The Device needs time to recalculate.
The BLU TRV will automatically adapt and gradually adjust its temperature readings.
The Device cannot fully close the valve even when the temperature is set to the minimum. The issue persists after successful calibration.
The plunger is a bit shorter than required to close your valve.
Attach a small metal disk, (approx. the size of a 1 Euro cent coin), to the black plunger tip to extend its travel.
The Device cannot take readings from an external temperature sensor to set the target temperature.
Underfloor Heating feature not enabled through the Shelly Smart Control app or the web interface of the Gateway Gen3.
Temperature sensing behavior with an external BLU H&T sensor paired with the TRV
If Underfloor Heating is enabled: The TRV uses data only from the external sensor disregarding the built-in sensor.
If Underfloor Heating is disabled: The TRV uses data from the external BLU H&T to correct the built-in sensor.
Enable the Underfloor Heating feature:
Login to the Shelly Smart Control app or access the Gateway Gen3 web interface.
Select the TRV you want to configure.
Go to Settings>TRV Behavior.
Enable the Underfloor heating feature.
The Device’s valve appears to be open, even though it is set to.
Shelly BLU TRV cannot be paired with any other Shelly devices. It only works with the included USB Gateway Gen3 (Shelly BLU Gateway Gen3 – https://kb.shelly.cloud/knowledge-base/shelly-blu-gateway-gen3), and up to 5 TRVs can be connected to one gateway.
Is it possible to use the device without a hub?
Yes, Shelly devices (except for Wave devices) operate independently without the need for a hub. They connect directly to your Wi-Fi network, and you can control them via the Shelly Smart Control app, web interface, or through integrations with platforms like Google Home, Alexa, Home Assistant and Samsung SmartThings.
Shelly BLU TRV has precise temperature control, maintaining your desired comfort level with an accuracy of ±0.1°C, ensuring a consistent and comfortable environment. For those moments when you need a quick warm-up, the Boost Mode can swiftly bring your room to the perfect temperature in no time.

Not the best shelly product, by far
I am a huge Shelly fan, but those radiator valves are not great.
1) Bad network connectivity, quite often
2) Insufficient strength of motor, leading to frequent decalibrations
