Hubitat integration (HACS) delay or refresh when lost?

I am slowly migrating my years old Huibitat system over to HA running on a RPi 5.
The connection works fine for most things, but I found a hiccough last night when the power cycled for a couple of minutes. The HA server booted fine, but the Hubitat server took longer and came up as disconnected.
Can I:

  • Delay the rescan of Hubitat after a boot, by say 2 minutes.
  • Automatically rescan when disconnection is sensed. (with timeout and maximum count.)

I guess it isn’t possible.
