Neighbors Hue Bulb appeared on my network map

[roygbiv856]

I don't own any Hue bulbs. Today, while setting up a Xiaomi wireless double switch, I checked my network map and found a Hue bulb acting as a router. https://imgur.com/a/x9cZVXL Seems like it's definitely routing zigbee traffic.

I added the bulb to home assistant. I can add it as a light, but I cant control it. I haven't paired any new devices in weeks, so I am not sure how it joined the network. Anybody know how to proceed? I am thinking I can ban it from my network, but I'd like to prevent any future foreign devices from joining my network!

Was permit_join set to true in configuration.yaml?

[roygbiv856]

No, it is set to false.

Maybe your neighbor is using the same default zigbee network encryption key.
But I have to say that I don't have much knowledge how zigbee works so this is just an idea.

This shouldn't happen anymore in the dev branch, probably fixed by #816
