Shelly BLU TRV 2-pack
Overview
The Shelly BLU TRV is a smart thermostatic radiator valve designed to deliver precise, room-by-room heating control with high energy efficiency. This 2-pack includes two radiator valve heads and a Shelly BLU Gateway, enabling both Bluetooth operation and Wi-Fi connectivity via the gateway.
With fine temperature adjustment down to ±0.1 °C, the Shelly BLU TRV allows you to maintain consistent comfort while reducing unnecessary heating. Smart schedules, boost mode for rapid warm-up, and external sensor support ensure heating responds accurately to real-world conditions rather than just radiator temperature.
The included gateway bridges Bluetooth devices to your Wi-Fi network, allowing full remote control, automation, and integration with popular smart home platforms. Designed to blend seamlessly into modern interiors, the Shelly BLU TRV is ideal for smart heating upgrades without rewiring.
