What It Does
Built for heating.
A smart radiator valve (TRV) with a ten-year battery and 99% radiator compatibility — room-level heating control that fits almost any existing radiator. LoRaWAN decoder: MClimate vicki payload decoder & codec (The Things Network)
Highlights
Ten-year battery life
Two standard AA lithium cells last up to ten years — room-by-room heating control across a whole estate without a recurring battery replacement programme.
99% radiator compatibility
Ships with M30×1.5 thread and adapters for RA, RAV, RAVL, ORAS and Oventrop valves, so it fits almost every radiator already installed in UK public-sector buildings.
Open-window detection
Built-in open-window detection cuts heating to the room automatically when a window is opened — prevents the energy waste that undermines most manual TRV installations in schools and offices.

Complete The Setup
You will also need a gateway.
Every LoRaWAN sensor needs a gateway to reach the internet. One gateway covers a whole building — the Milesight UG65 is the standard choice for most sites.
On The Platform
A device on its own, or part of the bigger picture.
Buy this device and run it yourself, or have it monitored on the Planetic platform — live dashboards, standards tracking and automatic alerts, with the compliance evidence kept for you.
Questions
Good to know.
- Do I need anything else to use this device?
- Every LoRaWAN sensor needs a gateway to reach the internet. One gateway covers a whole building — the Milesight UG65 is the standard choice for most sites. The gateway itself does not need a sensor to run.
- Is the price ex VAT?
- Yes — all prices shown are ex VAT. VAT is added at checkout where applicable.
- Can I have it monitored on the Planetic platform?
- Yes. Buy the device outright and run it yourself, or have it monitored on Planetic — live dashboards, standards tracking and automatic alerts, with compliance evidence kept for you.
