I have set-up the KNX binding in router mode and it is working fine for switches and rollershutters.
Now I added a switch which does provide the room’s temperature (MDT glass switch 2) as thing. Further I added a channel type Number to it and linked it to a point set to temperature/number:temperature.
If I set the KNX binding to Tunnel it works, i.e. shows the temperature, if I set the KNX binding to router it does not get any info and remains at NULL.
Set the the binding log-level to DEBUG (or TRACE if you don’t receive the desired information) and show the log when you send a value. And show your configuration. Mine is:
That’s ordinary enough; by default only state changes are logged.
If you did want to monitor for Item update-to-same, simplest is to make a little rule triggered on update that logs.
I tried setting a localSourceAdress. With and without having a dummy device in the KNX line.
Unfortunately that result in the bridge still showing online while the devices show offline. What kind of device do you have in the ETS for 1.2.100?
I am fine with only updating if there is a change. But with the binding set to router neither the initial value after openhab started, nor the changes come through or appear in the log.
Log with the binding set to tunnel and localsourceaddress set to 0.0.0.
I supose that when changing to router KNX sends the same information but the binding still does not get it.
