According Koenkk/zigbee-herdsman#81 it's possible to permit join for specific router only. This should help in case of some aqara sensors like (door sensor) which rejoin to network in on specific way not compliant with standard, so zigate coordinator doesn't see sensor after few days (after try to rejoin). Probably joining to aqara wall swich (with neutral - act as router) should solve the problem because it's aqara router.
It will be nice to have also button from UI or at least parameter in service with address or entity.
