Schedule Plus and Ness M1 interface

In 5 out of 10 instances, when I dim a GA, 2 second later it goes to 100%. ESpecially when I fiddle a bit longer with the GA. I have checked both log files (CGate and Schedule Plus) and I found that the M1 interface sometimes send a command to turn the last used GA to 100%. See below. The first 2 logs at 110235 and the following 2 log files at 110621.
Anybody came across this issue and has a solution? I am using Schedule Plus 4.12.2.2 but I don't think the problem is with the SP as I have the same issue when I dim the light on SP or on the DLT.
Thank you.

 

What version of Cbus interface is in the M1? Versions prior to V3 had major bugs that made them unusable. Unfortunately the firmware cannot be upgraded to V3. You need a complete new interface.

 

It is the version 3 M1 interface.

 

I don't know of any issues with the V3 interface that would give those symptoms. One thing worth looking at is to ensure every cbus group addresses is present in the M1. There is a known issue that the M1 Cbus interface misbehaves if it receives cbus messages for groups it doesn't know about (it's in the release notes). If you have added new ga's on the cbus side but not updated the M1 it could cause problems.

 

Thanks Ashley. Your suggestion fixed the problem. The groups were not in M1.
