Does anyone know what the visualisation option shows? Two specific questions:
Thanks
Line means communication between two devices.
End devices (usually battery operated ones) will have only one line to routers or the coordinator.
Routers are connected to other routers and sometimes to the coordinator.
All devices should have a path to the coordinator.
Numbers in these lines are about signal strength between two specific devices.
Between routers (or the coordinator) you might have two numbers, one if them is signal strength. Not sure about the second number.
Edit: when you first add your devices to network, the lines might not be drawn, it usually fixes it in next couple of hours.
Thank you!
So what happens in this picture in your opinion? The two devices pointed to with the arrow are INNR power outlets (which I want to use as repeaters). They seem to work fine but there is no line to the coordinator in the middle?
I had edited my first post with missing lines. Just give it some time, you still get your lines 
(assuming that these devices are added recently)
You are spot on - I just added them Thanks
@anon63427907 - I got my lines! But I have another question. I want to use the INNR outlets as repeaters and one of those is marked in this picture as B. A is a (magnetic) contact sensor that paired fine with main controller C.
But… Where A (contact) is going to be used is too far from C (controller). Just as a test, I have placed A (contact) about 50cm from B (the INNR) but the two don’t seem to connect and Home assistant is not seeing the contact sensor A.
Do I need to “re-pair” A, through B for that to work or should that sort itself out automatically?
some sensors are smart enough to find their route (i know some Aqara sensors prefer to be sticky, at least, this is claimed)
you can move to further of coordinator and closer to repeater and test. If there is a button on sensor to wake it up, use that. If it fails to connect, you might need to re-pair.
It’s an Aquara sensor… Let me try the button.
