Network Problem?

[allgo]

I currently have a small network that I use for programming practice (one 8gang neo, 8ch dimmer, V2 minder and a 360degree pir). With switch and dimmmer connectted all is fine. Once the PIR is connected all control via switch is lost and load controlled via PIR is permanently on.
Software/ Hardware burden no difference. But once I connect the C-Bus to Minder all is well again. The Minder does not have to be powered up, only connected via C-Bus terminals. Minder Burden not enabled. Any suggestions?

my first guess would be that the Minder is the only unit with the clock enabled.
Enable a clock in the Dimmer and see if that works

[allgo]

Clock in dimmer unit is enabled.
Is it possible, that due to the PIR a second clock pulse is required.

Only 1 clock generator is required per network.
