Shelly BLU TRV V2 is a smart radiator thermostat that controls heating room by room. It regulates the radiator valve automatically to the target temperature with ±0.1 °C accuracy, and an adaptive control algorithm adjusts to the individual room to avoid over- and under-heating. The enhanced motor makes valve movement quiet, so the thermostat is at home in a bedroom too. A built-in LED display shows the current setting, the temperature can always be adjusted by turning the knob, and Boost mode opens the valve fully when a room needs warming up quickly.
Important: the V2 version ships as the thermostat only. For Wi-Fi control and remote access you do not necessarily need a gateway — any Shelly Gen3 or Gen4 device with Bluetooth gateway functionality, such as a relay already in the installation, can take that role. The Shelly BLU Gateway Gen3 (EAN 3800235261934) is only required if you want to link external sensors such as Shelly BLU H&T or BLU Door/Window to the thermostat.
The thermostat fits M30 x 1.5 valves directly. RAV, RA, RAVL, Caleffi, Giacomini and M28 x 1.5 require the Shelly BLU TRV adapters set (EAN 3800238074760), also bought separately. Available as a 1-pack, 2-pack and 3-pack, so several radiators can be covered in one purchase.
Set up and controlled easily through the Shelly Smart Control app or your preferred smart home system — Home Assistant, Homey, SmartThings, Google Home and Amazon Alexa. Wi-Fi control runs through a Shelly Gen3 or Gen4 device with Bluetooth gateway functionality, or through the Shelly BLU Gateway Gen3, which handles up to five BLU TRVs.
Use cases
• Room-by-room control: each radiator gets its own temperature and schedule — the bedroom cooler than the living room.
• Remote control: raise the heat before you arrive home, and let it drop again when the home is empty.
• Boost on demand: turn the knob quickly or use the app to open the valve fully and warm the room.
• Manual valve control: hold the valve partly open as a percentage, independent of room temperature — useful during balancing or in rooms without a fixed temperature target.
• Night setback and workdays: fixed schedules lower the heating automatically and cut consumption.
• More accurate readings: an external Shelly BLU H&T measures room temperature away from the radiator, where the air is warmest.
• Airing out: a Shelly BLU Door/Window closes the heat while the window is open, and restores it afterwards.
Connectivity, mounting and battery
• Bluetooth 5 LE and Zigbee (802.15.4) — range up to 10 m indoors and 30 m outdoors.
• Wi-Fi and remote access: use a Shelly Gen3 or Gen4 device with Bluetooth gateway functionality — a relay you already have, for example — or the Shelly BLU Gateway Gen3 (EAN 3800235261934).
• External sensors (Shelly BLU H&T, BLU H&T ZB, BLU H&T Display ZB and BLU Door/Window) require the Shelly BLU Gateway Gen3 — up to five BLU TRVs per gateway.
• Valve connection M30 x 1.5 with a nickel-plated brass ring. The adapter set (EAN 3800238074760) covers RAV, RA, RAVL, Caleffi, Giacomini and M28 x 1.5.
• Built-in temperature sensor — the thermostat can run autonomously without a gateway. Supports BTHome for Bluetooth-based automations.
• Two operating modes: TRV mode with automatic temperature control, or manual valve control as a percentage.
• Battery: 2 x AA 1.5 V (included), up to 2 years of life.
• Dimensions 78 x Ø54 mm, weight 107 g. Operating temperature -20 to +60 °C, humidity 25-80 % RH.
• Available as 1-pack (EAN 3800238074746), 2-pack (3800238074920) and 3-pack (3800238074937).
• Box dimensions: 58 x 58 x 85 mm (1-pack), 116 x 58 x 85 mm (2-pack), 174 x 58 x 85 mm (3-pack).
• The adapter set and the BLU Gateway Gen3 are not included with V2 — they are bought separately as needed.
