we also faced this, while doing roaming.
i workaround is to have something like:

#!/bin/sh

iw event | while read -r LINE; do
  case "$LINE" in
    *': del station '*|*': new station '*)
      # wlan0-1: del station 00:21:6a:32:7c:1c
      # wlan0: new station dc:9f:db:02:b8:ee
      ...your own logic here...
    ;;
  esac
done

what we do e.g. is if a station connects for the
first time and signal is below -70, we just kick.

#!/bin/sh

dev='wlan0-1'
mac=...
ubus call hostapd.$dev del_client '{ "addr" : "$mac", "reason" : "assoc toomany", "ban_time" : 10000 }'


if the same mac connects during a specific time again,
we dont kick 8-) - really, it's just a workaround.
