Hi, I’ve been struggling how to add Sonoff smart switch battery level.
I have added sonoff LAN through hacs integrations, successfully connected bridge socket and switch, but cannot find anywhere in entities sensor for battery level, whenever I’m in ewlink app I can find battery status in there.
You can find it if you go to the device itself (Configuration → Devices → search for your device).
There you can find the Device Info and the Diagnostic “Card”, which should contain the power level. By clicking on the Battery Icon, the id should appear.
