Which version do I need?
868M denotes the EU868 LoRaWAN band, correct for the UK. The socket standard is a separate ordering choice recorded in the part number: 13A-UK (Type G, 13 A) for the UK, 16A-EU (Type F), 16A-FR (Type E), 15A-US (Type B), 10A-AU (Type I), 10A-CN and 16A-CN. The bare SKU WS523-868M does not state which socket type is supplied, so confirm at order. Plug size differs a little between socket types.
Typical applications for the WS523-868M
- Wireless control of indoor lights
- Fan control
- Heater control
- Machine and appliance switching
- Appliance-level energy consumption measurement
- Overcurrent alarming on plugged loads
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 WS523-868M 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.
CN470, US915, AU915, KR920 and AS923 are a different radio and therefore a different build. Milesight makes them and we can order them: tell us where the devices are being deployed and we will confirm the part number, price and lead time.
Not sure which band applies where? The Things Network publishes the LoRaWAN frequency plan for every country.
