Shelly BLU TRV vs SwitchBot Smart Radiator Thermostat (2026)

Updated September 2026

Data from Amazon and official Shelly and SwitchBot sites.

2026 verdict

Winner

€29.00

The SwitchBot Smart Radiator Thermostat comes out ahead of the Shelly BLU TRV in this radiator valve matchup, helped by a lower price, a slightly higher owner rating, frost protection the Shelly valve omits, and integrations that stretch to Google Home, Alexa, Apple Home, Samsung SmartThings, Home Assistant and Matter through a SwitchBot Hub. The Shelly BLU TRV answers with a longer warranty, longer battery life and one extra connectivity path, since it reaches Wi-Fi through its own Shelly BLU Gateway on top of Bluetooth, though that gateway needs to stay powered for remote and voice control to keep working. Both display live temperature on-device, read the room with a built-in sensor, and go without geofencing or a child lock. Buyers chasing the lowest price and the widest ecosystem reach should pick the SwitchBot Smart Radiator Thermostat; anyone who values a longer warranty and battery life, or is already running a Shelly BLU Gateway for other sensors, gets more from the Shelly BLU TRV.
