Check and see if your thread network is on the same channel as your Hue network. If they are, change the Hue channel and see what happens. I have been having periodic device drops. When I ran Thread Doctor, a number of them had very weak connections despite the fact that they were very close to a border router. Once I changed my Hue network from channel 25, the devices all came back online
