## Description

The Shelly BLU TRV is a smart thermostatic valve head, designed to be retrofitted onto pre-existing radiator grills and offering precise climate control. The BLU TRV can connect to a wider Shelly network natively via Bluetooth or through WiFi with the included Shelly BLU Gateway, and delivers temperature control with adjustments as precise as ±0.1°C.

The Shelly BLU TRV features a sleek and unobtrusive design, engineered to be installed like a standard radiator head valve on a pre-existing radiator and offering precise temperature control. The smart valve can provide accurate temperature control by using the rotatable dial on the TRV itself with a physical display on the device, or by creating a smart schedule in the free Shelly app for adaptable heating routines, ensuring your home is warm when you arrive and reducing unnecessary energy expenditure when you're away. Also included is a boost mode, quickly bringing the room up to the specified temperature faster than a normal temperature control would allow.

The Shelly BLU TRV is natively compatible with Bluetooth connectivity, and can be instantly included on the Shelly app through Bluetooth pairing for a simple and pain-free first time setup, as well as linked with external sensors like the Shelly BLU H&T Bluetooth temperature and humidity sensor, or the Shelly BLU Door and Window Sensor for a fully smartv heating and cooling system. The TRV can also connect to the wider Shelly network over WiFi by using the included Shelly Gateway, offering a bridge between WiFi and Bluetooth devices to communicate.

The TRV is powered by two included AA batteries, with an extremely low battery usage profile and a lifespan of up to two years on a single set of batteries.
