- Freeze protection in unoccupied rooms
- Cutting heating waste through open-window detection
- Tamper-resistant TRV control in public areas
Buying guides for this product
Frequency band
Supplied on EU868, the LoRaWAN band used in the UK and across Europe. That is the default and you do not need to ask for it — the -868M in the part number is the EU868 build.
The same WT101-868M unit also covers IN865 and RU864. Those bands share the 863–870 MHz radio with EU868, so one device can be set to any of them in its own configuration — no different part number needed.
Not sure which band applies where? The Things Network publishes the LoRaWAN frequency plan for every country.
