I’m using zigbee2mqtt with this CC2531 stick with external antenna. Despite the external antenna, there is one Xiaomi Aqara door sensor in the house for which the state is only very rarely updated. I assume that it is right on the edge of the stick’s range. I put a Tradfri signal repeater as a router in the same room in the hope that coverage would improve. But, no luck.
I read somewhere (on this forum? can’t find it now) that Aqara devices will only connect to the coordinator and not a router. I assume that’s what is happening now.
Any suggestions for how to improve coverage for the door sensor? If I installed an wired Xiaomi/Aqara device in the room as a router, would the door sensor connect to it if the coordinator was still a CC2531?
