ZHA XBee switch state - how not to store?

I have one XBee as coordinator, connected to Rpi with HA, and second XBee as router. They are paired without problems. When i disconnect the router from power - the states of router’s GPIO (they are available as switches in HA) remaining the same (last state) and they are not go to “unavailable” even after reboot. There are no any settings for this nor in ZHA, nor in device configurations. How i can tune this behaver? I d’t want to store the states of that switches…
