Experiment: Turned off the coordinator for several days.
When turned on, some xiaomi devices fell asleep and on waking up refused to connect to the coordinator cc2561. (wall switches without zero (QBKG04LM and QBKG03LM), motion sensors (both versions RTCGQ01LM and RTCGQ11LM), leakage sensor SJCGQ11LM, wall-mounted remote control WXKG02LM.
When trying to control the switches, we get the error:

Re-activation, awakening, etc. does not work. It helped only to exclude the device from the zigbee network and re-enable it.
