Xiaomi Smart Socket (Zigbee): purpose of Channel sensor_plug

Hi there,

I’m just wondering for what is the channel

Switch Plug_Active <switch> { channel="mihome:sensor_plug:<GwID>:<ID>:inUse" }

for?

Switching the item via sitemap leads to the following error message in the log:

==> /var/log/openhab2/openhab.log <==
