I'm showing "ignore SupervisionGet" in the log when child devices are operated. This is with a Zooz ZEN16 using the builtin Zooz MultiRelay driver on 2.2.3.118.
Also, child devices are not receiving events such as switch on/off when operated. The events are showing as being for the parent device.
That's more than likely not helping the lock situation.
We are working on the busy message issue, so we probably want to get that hot fix in place then see if that resolves your lock issue.
