Smart thermostatic radiator valves (TRVs) replace your existing manual radiator valves, giving you precise, room-by-room temperature control from your smartphone — helping you stay comfortable while cutting heating bills.
Traditional heating systems heat your entire home to one temperature, wasting energy in rooms that don't need it. Shelly TRVs solve this by letting you set individual schedules and target temperatures for each radiator, so you're only heating the rooms you're actually using.
Shelly TRVs fit directly onto most standard radiator valves and connect to your home Wi-Fi. Once installed, you control them through the Shelly app — setting schedules, adjusting temperatures remotely, or letting the built-in sensor maintain your ideal room temperature automatically.
Whether you're upgrading a single room or your whole home, Shelly TRVs offer an affordable, flexible way to make your heating smarter.
A smart TRV replaces your existing manual radiator valve and allows you to control the temperature of individual radiators via an app, schedule, or voice command — rather than adjusting them by hand.
Do smart TRVs work with my existing boiler?
Smart TRVs are compatible with most standard gas, oil, and electric boiler systems. They work by controlling the flow of hot water into each radiator independently.
Can I install a smart TRV myself?
In most cases, yes. Smart TRVs are designed to fit standard radiator valve fittings and can be installed without a plumber. Most come with a range of adapters to suit common valve types.
Can I control smart TRVs when I'm away from home?
Yes — as long as your TRVs are connected to your home network, you can adjust temperatures remotely through the associated app from anywhere in the world.
