Data from the official Meross and Shelly sites.
2026 verdict
The Shelly BLU TRV takes this radiator valve comparison over the Meross Smart Thermostat Valve, backed by a better owner rating, a 2 year warranty against 1, and Bluetooth alongside Wi-Fi, which lets it pair locally and respond quickly rather than depending entirely on a cloud round trip. For a device that has to sit on a radiator for years, the longer warranty and the stronger reception are the arguments that matter most. The Meross Smart Thermostat Valve answers on compatibility and cost: it is the cheaper way to automate a radiator, and its hub bridges into Apple HomeKit as well as Google Home, Alexa, Samsung SmartThings and Home Assistant, where the Shelly does not reach HomeKit at all. In an Apple household that single point can settle it. Choose the Meross Smart Thermostat Valve for HomeKit support at a lower price, and the Shelly BLU TRV for the better-rated valve with twice the warranty.
