Hi, is there any documentation on how zigbee device pairing works in home assistant? specifically I would like to understand the zigbee security config that would allow all kinds of zigbee devices to join the zigbee network under HA.
I understand that there is a network key (hop-by-hop encryption) and an APS/trust center link key (end-to-end) which would need to be identically configured in both the coordinator and end devices (and routers if any).
I found the answer in an old post XBee serial communication - #16 by Shulyaka
A default global trust center link key defined by the ZigBee Alliance has the ASCII hex value of 5A 69 67 42 65 65 41 6C 6C 69 61 6E 63 65 30 39, or the equivalent string “ZigBeeAlliance09”.
