Can the network ID of a device change?

Hi! Im having this same issue with a magic cube from Xiaomi, it keeps changing the device id so I have to re-pair it, but it will only work for a couple of hours. Any idea how to prevent this?

This has been reported with some zigbee lightbulbs of particular brands.

Bulb Device Network IDs change randomly

I have a bunch of OSRAM Lightify RGBW bulbs and dimming switches. I’m using adamoutler’s Lightify Dimming Switch Zigbee device handler, which is associated with the bulbs by their device network IDs. Every few days, one or two of the bulbs randomly changes its ID, which means I can still control the bulb via the SmartThings app but not via the physical switch (until I log into the IDE and update the network ID, losing wife approval points each time). I’ve confirmed it’s the bulb whose ID changes, not the ID in the device handler, because I saved all the device info in the IDE and compared it after it happened again. Has anyone else experienced this before? Any recommendations?

It appears that the device drops off the network and then rejoins and gets assigned a different ID. It’s really weird, and I’m not quite sure why it happens, but it does seem to happen with some devices.
