Hi folks,
I’m very new here, have a 20 year old instabus installation, wiregate to connect to the bus and OH1 installed on a RPi3 - which is working fine. Now I got an echo and therefor want to switch to OH2.
I tested a very small fresh installation of OH2 with just one simple item - a switch to a light, which works properly with OH1
The item in OH1:
Switch Licht_EG_WZ "Licht WZ Tisch M" (gEG_WZ_Tisch, sgLichter) {knx="1/0/9"}
Switch Licht_EG_WZ “Licht WZ Tisch M” (gEG_WZ_Tisch, sgLichter) {knx=“1/0/244”}
The item in OH2:
Switch EG_EZTisch_M_KNX "Licht Esstisch mitte (knx)" <light> [ "Lighting" ] {knx="<1/0/244"}
switching the light in OH2 leads in and overflow of permanently sended telegrams to the bus:

which results in a flickering light with no update on the item - in OH1 item is perfectly updated.
Unfortunatly I don’t have the original ETS configuration, but since the item updates in OH1 are working, I’m asuming that reading works on the same GA.
No idea at all!
Can you please help me, I’m desperate and Alexa whant’s to do her Job 
thanks in advance,
Herbert
