This may or may not be relevant, but just in case:

Zigbee devices (bulbs, sensors, switches, outlets) randomly failing beginning March 2016

I am seeing a number of reports in many different threads since the March meltdown and the subsequent implementation of the new scheduler indicating random problems with a number of different zigbee devices, including smart bulbs, motion sensors, pocket sockets, etc. Most people are reporting this as a failure of the device, but I’m not sure it is. It may be a failure of the cloud to properly record the events, or database corruption, or local flooding. It may be devices using a device handler that has the known millisecond problem. The new scheduler which was rolled out in March has a missing converter and treats milliseconds as seconds, so device handlers with programmed delays will wait 1,000 times longer than they should. This might cause a timeout, or what appears to be a failure t…
