[Bug] Shelly Flood 0% Battery
Hello, the Shelly Flood does not show the correct battery level in Homebridge and in the Home App. Everything else is working fine. In the web interface is the correct battery level. 

I have reset the Shelly and restarted the Homebridge server with no success. 

Maybe it is the same problem as with the door/window sensors
