afaik ETS does only provide 3-tier and 2-tier style. There are some free to use programs to calculate the one from the other, as this is only a display feature.
they already introduced the free-level style group addressing in ETS4 and is working at my home with the trial version of ETS5. So the following is valid:
3 tier: 1/1/1
2 tier 1/1
1 tier: 1
So either the binding does not accept 1-tier group addresses or there is a valid configuration for the binding in openhab
OK, good to find this Information after almost one day of debugging my configuration.
KNX 1 Binding had support for this format. How can a user find out about a missing support in the successor version? Even a Trace of “calimero” and “org.openhab.binding.knx” does not give any indication on a missing support for 1 tier addressing. I just got:
20:43:01.741 [DEBUG] [x.internal.handler.DeviceThingHandler] - None of the configured GAs on channel 'knx:device:bridge:generic:Light' could handle the command 'ON' of type 'OnOffType'
Please add some warnings into the documentation or just add support for this stuff.
Now I know the Issue, but for others it might be as frustrating as it was for me.
just for the new user to this road of wonders (and to make it crystal clear, because I did not understand Udo´s explanation to my problem immediately
1 tier address 1 must be entered as 0/0/1
1 tier address 2 must be entered as 0/0/2
…
1 tier address 255 must be entered as 0/0/255
1 tier address 256 as the next address in sequence must be entered as 0/1/10
and for the next, you can use my python program
