Hello all,
i extented the jeelink binding, that it will also recognize the EMT7110 energy meter.
So far it works i can read the data in the item, but the thing ist all the time offline.
in the openhab console i found the follow error:
22:58:36.162 [WARN ] [nfig.discovery.DiscoveryResultBuilder] - Representation property 'id' of discovery result for thing 'jeelink:emt7110:7c86e4e0f3:8496' is missing in properties map. It has to be fixed by the bindings developer.

Do someone have a hint, what i did wrong? How is the state of a thing working? And what is this error with the id?
thanks 
PS: i will create a MergeRequest, when everything works well.
