The light actuator/dimmer can still be controlled by a KNX button with the same group address, so if Comfort fails the button is still able to control the light
However the PIR sensor should have a different group address which goes to Comfort so that you can have a much better control of when the light turns on and off
If Comfort fails then the PIR will not trigger the light but the switch is still able to do so. I think the logical capability that you can achieve with Comfort will outdo the disadvantage of not having the PIR trigger the light should Comfort not work. For example you may not want the light to turn on in the daytime. Or you may want to disable the light turning on and off when there is a party
The KNX group address of the PIR sensor can be mapped to a Counter or a Virtual Input.
If Virtual Input then it will activate the zone type and the Zone Response. It is exactly like a physical zone is activated so if the system is armed then it can cause an alarm according to the zone type
The zone On Response can send KNX Commands eg
If Security Mode = Off then
KNX On UCM02 70
Do Response KNX-Off after 300 seconds using Timer01
End if
-------------------------
Response KNX-Off
KNX Off UCM02 70
Or add more conditions
If Security Mode = Off AND Hours > 20 then
KNX On UCM02 70
Do Response KNX-Off after 300 seconds using Timer01
End if
You can also map the KNX group address to a counter, in which case the Counter Response would be similar
if Counter01 >0
KNX On UCM02 70
Do Response KNX-Off after 300 seconds using Timer01
But unfortunally, it doesn't look like the UCM/KNX can direclty get the KNX telegram sent from the Response... Can you confirm please ?I do not understand what you mean by the above.
A Response can send a KNX telegram to any group address as in the examples above
