Zigbee2MQTT - LQI and map issues

Hi guys,

I have a Zigbee setup with numerous Ikea Tratekt plugs around the house to create a mesh network. Here’s some screenshots below:

Couple of questions:

  1. In the map, why are some end device seen to be floating without a connection? They work without issue, but appear disconnected. Re-pairing did not work to make them appear connected in the map.
  2. My understanding was that the routers (Ikea plugs) mesh with each other. The plugs are within a decent distant to each other and theoretically should create a strong mesh network. However, some of my devices and even the plugs have low LQI. Do devices show low LQI if they jump between routers even if there is strong signal between the routers and coordinator?

Many thanks
