About this product
Shelly BLU TRV 2-pack is a kit assembled specifically for a flat or room with two radiators: the box holds two Shelly BLU TRV thermostatic heads and a single Shelly BLU Gateway Gen3, which is enough to bring both radiators online at once.<br><br>Each BLU TRV head mounts on the radiator valve via the standard M30x1.5 thread, and the box includes adapters for Danfoss RA, RAV, RAVL, Caleffi, Giacomini and M28x1.5 variants. The head has a built-in temperature sensor, a 7-segment LED display and a rotating knob for local adjustment in 0.1 degree steps.<br><br>BLU TRV works over Bluetooth and is powered by 2 AA 1.5 V batteries (included), with up to 2 years of battery life. The Gen3 gateway plugs into a USB-A port and bridges to WiFi, so both heads can be controlled from the Shelly Smart Control app with weekly scheduling, Boost mode and scenes.

Where it works
Use cases
A Chisinau family wants a separate day/night schedule for two rooms.
Mount one head on the living-room and one on the bedroom radiator, gateway in a nearby USB port.
A couple out at work all day wants the home warm only in the evening.
Set a lower temperature when nobody is home and return to comfort before arrival.
A room aired daily in winter without wasting heat through the window.
Link the heads to a BLU door/window sensor to cut the heat when a window is open.

Frequently asked questions
How many devices are in the Shelly BLU TRV 2-pack box?
The kit contains two Shelly BLU TRV thermostatic heads and a single Shelly BLU Gateway Gen3, plus AA batteries and mounting adapters for each head.Do I need a gateway to use the BLU TRV heads?
For app control, remote scheduling and integrations yes - and it is included in the kit. The heads work locally over Bluetooth, but the bridge to WiFi is the Gateway Gen3.Will the heads fit radiators in Moldova?
The head uses a standard M30x1.5 thread, and the box includes adapters for Danfoss RA/RAV/RAVL, Caleffi, Giacomini and M28x1.5 variants, covering most common valves.How long does the battery last and what type is used?
Each head is powered by 2 included 1.5 V AA batteries, with an estimated life of up to 2 years depending on use.Is a single gateway enough for both heads?
Yes. One Gateway Gen3 serves up to 5 BLU TRV heads, so a single unit comfortably covers the two heads in this kit.Can I adjust the temperature on the head itself, without a phone?
Yes, each head has a rotating knob and a 7-segment LED display, allowing local adjustment in 0.1 degree steps even without the app.
