Very unstable network. Why?

We are created 2 network connected over bridge.
There is many connection errors and hardware troubles like no reaction on PEIRL by occupancy sensor.
I have idea that the networks was planned faulty...
Can anyone look at my project repository and give some answers?

If its unstable and your sure the cabling is good and there are no external influences I would be looking at network burdens and possibly clock. A quick look through shows that no clock or burden is enabled in the software although you may have a physical burden, I cant tell from here

 

Usually if a network has intermittent communication problems, it is due to one or more of :

• Burdens
• Not enough power supplies / voltage drops
• Too many clocks
• Electrical noise
• Too many units

Use the C-Bus Diagnostic Software to check to see whether you are getting lots of errors on the networks.
