Stop heating rooms nobody's in

Control every radiator independently from your phone, with open-window detection and frost protection built in. Most homes need more than one — buying as a set costs less per valve than ordering separately. Backed by a 30-day return guarantee.

  • Control room-by-room heating from your phone via the eWeLink app — no more guessing what the radiator's actually doing
  • Zigbee 3.0 connectivity pairs reliably with a compatible hub for fast, stable smart home integration
  • Open window detection automatically cuts heating when a window opens, saving energy without thinking about it
  • Child lock and frost protection keep the system safe and pipes protected from freezing
  • Works with Alexa for voice control, plus 6 months of usage history to fine-tune your heating schedule

Frequently asked questions

➤ Do I need anything else to use this?

Yes — a Zigbee 3.0 compatible hub or bridge is required to connect and control the valve.

➤ Does it fit my radiator?

It fits standard M30x1.5mm threaded valves, compatible with most heating systems.

➤ Can each valve be controlled independently?

Yes, every room can be set and adjusted separately for whole-home comfort.

➤ Why buy more than one?

Each valve controls one radiator, so most homes need several — buying as a set works out cheaper per valve than ordering one at a time.

➤ Does it work with Alexa?

Yes, plus Apple Home via Matter Bridge and Home Assistant.

➤ What powers it?

3x AA batteries (not included).

➤ What if it's not the right fit for me?
