Duplicate device?

I have a system, installed ages ago (and no not upto date - “not broke; don’t fix” scenario) that has suddenly stopped working.

It seems there is a duplicate device entry

Oct 08 21:40:32 DietPi-Monitor service-runner[1936]:   "0x00124b0018ecdf16" [label="{0x00124b0018ecdf16|Coordinator|No model information available|online}"];
Oct 08 21:40:32 DietPi-Monitor service-runner[1936]:   "0x90fd9ffffe6d0dcf" [label="{Standing Lamp|Router|IKEA TRADFRI LED bulb E26/E27 980 lumen, dimmable, white spectrum, opal white (LED1545G12)|offline}"]       ;
Oct 08 21:40:32 DietPi-Monitor service-runner[1936]:   "0x90fd9ffffe6d0dcf" -> "0x00124b0018ecdf16" [label="170"]

How can I remove the second device?

There is no trace of duplicate entry.
3rd row:
“0x90fd9ffffe6d0dcf” -> “0x00124b0018ecdf16” [label=“170”]

This is the way in network map to express that signal strength is “170” from device 0x90fd9ffffe6d0dcf (Standing Lamp) to 0x00124b0018ecdf16 (Coordinator)

I realised that after I’d posted it. I ended up deleting the device using the NR dashboard and then re-pairing it and it seems to be OK now.

Cheers
