Good Morning,
i have an issue with the battery status of one of my Sonoff TRVZB (Zigbee thermostatic radiator valve). It does not show the battery status. I waited for more than 24 hours but nothing changed.
It only shows a blinking % or a ?.
It´s integrated with Zigbee2mqtt.
Any ideas what to do. Three other TRVZB work as expected.
thx for your ideas
Markus
