For Sonoff iHost:- since the update to eWeLink Cube ver 2.13.0 IKEA VAALHORN type E2134 Zigbee Motion & Light Level Detector, Battery Level is showing as ‘Unknown %’ and Light Level is showing as ‘-- lux’ meaning that no low battery notification will be generated and any scene that uses a defined Light Level in the IF statement will not run.
Reported to Sonoff under ticket ID277067.
Thank you Sonoff - This issue now seems to be resolved with the release of eWeLink Cube ver 2.13.1
