Milesight WT102 - Smart Radiator Thermostat
Free shipping within the Czech Republic on purchases over 120 EUR.
The Milesight WT102-868M is a LoRaWAN® radiator thermostat that regulates room temperature by driving a hydronic radiator valve with a built-in stepping-motor actuator. It supports automatic and manual control with up to 16 customized heating plans, open-window detection, freeze protection and child lock, and can use its onboard NTC, an external NTC or a paired WT401 as the temperature source.
It is self-powered through thermoelectric harvesting from the temperature difference at the radiator, so it needs no batteries or wiring. It communicates over LoRaWAN® Class A/B, stores up to 1000 records with retransmission, and is configured via NFC. Default M30 × 1.5 mm valve fitting with adapters for RA/RAV/RAVL/Giacomini/M28.
Before you install
- Setup: via the Milesight ToolBox app (NFC).
- Power: self-powered from radiator heat (water >45 °C), or USB-C — no batteries.
- Control: regulates the radiator valve; remotely via a LoRaWAN gateway (sold separately).
