Hello again, I just ran some test with ETS and it seems that writing 1bit to the group address for zone 1 bypass is working fine. I tested this by writing 0 or 1 and checking with the comfort keypad that the zone bypass was correctly switched off or on. But I still don't understand the feedback I get from the UCM/KNX (I wrote the EEPROM again just to be sure) : When writing a 0, I get a response for zone 1 with 0, but I don't get that response when writing a 1 (even if set to on with the comfort keypad). The messages sent to the bus when setting bypass OFF (through KNX or keypad) are : from bus L 1.1.1 10/1/17 Zone Trouble 6 6 Bit Write $00 from bus L 1.1.1 10/0/1 Zone (1) 6 6 Bit Write $00 Which looks fine, I can tell that zone 1 is bypassed. BUT if setting the bypass ON (through KNX or Keypad), I only get these on the bus : from bus L 1.1.1 10/1/10 Alarm Type 6 1 Byte Write $10 | 6 % from bus L 1.1.1 10/1/3 Alarm State 6 6 Bit Write $00 from bus L 1.1.1 10/1/20 Alarm State (Value) 6 1 Byte Write $01 | 0 % I would expect to receive a "Zone 1" (10/0/1) with a value of 1 or something. How could I deduct from these 3 messages that zone 1 has been bypassed ? Also note that I'm using address 11/0/1 to set the bypass status, and that the response (in case of bypass OFF) is coming from 10/0/1, which correspond to the "Comfort to KNX" zone status. But that seems logical. Do you have any clue ? Are the received messages the normal behavior ? Again, any hint would be appreciated Thanks again.
