We use CBUS to control curtain movement. The curtains are moved by a timer in C-Bus and also by pressing wall buttons. The coding uses ‘curtain’ flags to keep track of whether the curtains are open or closed.  Changes to the flag trigger a counter in Comfort that then is programmed to bypass the PIR in the appropriate area. (Without these bypass and unbypass instructions closing or opening of the curtains whilst we are away sometimes sets off the alarm when the temperature differential interprets it as a movement.)
Looking at the Comfort log when the curtains are triggered by a timer we get multiple bypass instructions.

When the curtains are triggered by a button we get a repeated bypass/unbypass

Why would instructions repeat when CBus is only executing one flag change to initiate the process?
