What It Does
Built for heating.
A smart thermostat and HVAC controller with a 4.2-inch LCD — multi-mode heating and cooling control over LoRaWAN, for spaces a radiator valve cannot reach. LoRaWAN decoder: Milesight WT201 payload decoder & codec (GitHub)
Highlights
HVAC zone control
Supports furnaces, air conditioning, heat pumps and boilers across 24VAC two-pipe and four-pipe configurations — covering the range of HVAC plant found in schools, healthcare and commercial social housing.
LCD display on-wall
A 4.2-inch LCD shows the current temperature and setpoint directly on the device, so building users and facilities staff can read and adjust the room without accessing the dashboard.
LoRaWAN Class C
Class C operation keeps the radio receiver continuously open, so setpoint changes sent from the platform reach the thermostat within seconds rather than waiting for the next uplink window.

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.
