Sonoff Zigbeemesh

why is my zigbee mesh looking like this?
i have 2 zigbee wallplugs that are hoovering around, not connected with the zigbeedongle. any idee how to strengthen my mesh?

Reload your chart. If they are still showed as disconnected try to pair them again.
You don’t have to trust this charts so much. If plugs are working, sending data, you can turn them on off they are online.
