It‘s OH 2.4.0-1
I tried discovery multiple times but it doesn’t work.
But I found this in the log:
2019-08-25 16:24:20.426 [WARN ] [re.thing.internal.ThingFactoryHelper] - Could not create channels for channel group 'sensors' for thing type 'shelly:shellyflood:6946E0', because channel group type 'shelly:floodSensor' could not be found.
Maybe it helps.
