my first post here, sorry if lame. Just gave up after many searches and readings
OH3.0.1, KNX binding 3.0.1. Raspberry Pi4, latest stable openhabian. IP gateway (tunnel) online, KNX devices (things) online, OH listens KNX bus and gets evrything (sensor values, actuators status), but DON’T SEND commands to KNX bus. Made simple Thing and swich channell, linked with Item swich just to test simple OF/OFF for light - it receives status from KNX actuator, but not send command to it. Checking KNX bus by ETS5 - nothing goes to KNX bus when that OH3 swich is “pressed”, complete silence. This makes my crazy - where to look for the problem, what I making wrong? KNX as such working fine, binding seems OK (although there is some instabilities, bridge goes offline time to time), OH model for other parts (i.e. Modbus) works fine and now just trying to build KNX part, but can’t overcome that communication problem
Just realized that if I try to send command to KNX bus, binding disconnects (error - maximum send attempts) and reconnects after while, but nothing goes to KNX bus. Log looks like this:
