Is there any way to force initial state of non-battery devices?

[krasatos]

Hello,
I dont know if i should ask this here or on zigpy but here it is:

I am using a flashed sonoff ZB gateway with ZHA integration.
I am trying to figure out how to force the power-on state of my several switches / lamps of the mesh (in the case of power failure or physical switch flip off/on).
I tried listening to zha_events in HA, but nothing is reported there when devices reconnect to the mesh.
Is there a way to configure the devices themselves (like wifi tasmotas poweronstate) or to have an event trigger home assistant as soon as they come back online?

Thank you in advance and please, if I should ask somewhere else, let me know.
