Call your insurance carrier. Check every electronic device in the
house first before filing the claim. Clock radios, microwaves, laundry
appliance controls, HVAC systems operation, etc. All should be 100%
covered by insurance. Lightning is noted for doing weird things, so
expect surprises that defy logic. Limit your diagnosis and repair to
those things crucial to keeping the palazzo functional until the
insurance company repair contractors arrive. Good luck.
