Hello there !
Juste new on the forum but i follow haos and zigbee devices since years !
But today something really strange happened : I have a few zigbee devices at home (mostly from ikea) with integrations and such. But while adding a connected socket i just spotted two new devices in zigbee2mqtt list, which i’m sure i never possessed.
I firstly thought that while adding a device (i add or reconnect some quite regularly), maybe a neighboor juste happened to do the same, but i can’t know when they have been registered. The last seen date from 2 weeks ago and i’m pretty sure (okay, maybe 70% sure) i didn’t sync any device since a month.
My question are the following : Should i just blacklist them or remake a whole mesh ?
From what i understand from zigbee protocol an added device have private keys of the whole and is able to receive and send commands. It is really the case ?
I don’t really believe a hacker suddenly got into my mesh, but if it was the case and my assumption were true, i guess i should consider the mesh as compromised.
Additional question : If the previous guesses are correct, is there a way to rebuild and reconnect all devices in a easier way than resetting everything, and adding all 22 devices one by one ?
Thanks for your futur answers
