Adding new device "unlinks" older one

Configuration Zigbee
1

First of all: Sorry if it’s a duplicated one but I couldn’t find anything describing my situation! If there is a similar thread please redirect me to it! =)

My problem is the following:
My home assistant runs on an Intel Nuc and I am using the SONOFF Zigbee 3.0 USB Dongle Plus ZBDongle-P. Using Z2M to communicate with my devices.
Best to explain my problem is looking at my Z2M-Card

As you can see there are 4 devices not linked to any router, namely:

  • Sensor_Temperatur_Badezimmer,
  • Sensor_Temperatur_Schlafzimmer,
  • Sensor_Temperatur_WC and
  • Sensor_Fenster_Schlafzimmer

There are always 4 devices not linked and whenever I want to link one of those another one gets unlinked to any router. Just before writing this topic the sensor Sensor_Temperatur_WC was linked but Sensor_Temperature_Kinderzimmer wasn’t. Like those swaped places.

Hopefully someone can point me to the right direction, and why I see this kinda behaviour!

Thanks in advance

OK, but are they working? Those network maps can be very misleading.

To start with, connections in a Zigbee network change all the time - what you’re seeing is only a snapshot. On top of that, end devices connect and disconnect constantly. The links you see do not come from the coordinator polling the sensors; the sensors report in at intervals - sometimes long ones. After a restart all the sensors will appear as unavailable, sometimes for half an hour or more.

If the sensors are working, they’ll reconnect as soon as they have something to report.

THIS.

If it’s working stop looking at the map it WILL make you chase your tail.

They all seem to work…I will investigate some more! Thanks for the help =)
