Hello,
I thought sharing my experience.
In summary I noticed that Qubino relays and dimmers with version 1.3 have aggresive (5 min) periodic power reports enabled by default which risks congesting the Z-wave network. In my case, I have about 30 actuatators like these, and about 30 sensors that report on light/temperature/movement. I also had polling enabled for the Qubino acturators at 1h intervals.
For the 1 relay/dimmer the parameter for time interval reporting is 42 with 2 decimal format. For the 2 relays the relevant parameters are 42 and 43, both are 2 decimal. For now I set them to 3600 seconds reporting time interval, but time interval reporting can be disabled by setting them to 0. Power reporting is still active on power consumtion change. I left them with 1h reporting, while I disabled polling, and during absence is easier to troubleshoot if one is faulty.
My regards, Horia
