Found this 3x in KNX.things file in a sequence.
[al.channel.GroupAddressConfiguration] - Failed parsing channel configuration ''.
I checked the 324 lines in the file various time but can´t find the mistake. Seems to have something to do with group address notation.
Is there a validation tool available or debugging hint?
Have you found the cause of the error message?
I have the same problem
I am afraid there will be no solution without seeing your .things file.
I have now checked my knx.things again and now I think it comes from the empty “stopMove”
Type rollershutter : ChannelG_2 "Lamelle Esszimmer Süden Links 4M4" [ upDown="2/3/44", stopMove="", position="2/5/9+<2/7/14" ]
I will test that.
