We always run around shutting crap down, like heat pumps, tvs and major electronics when lightning in the area.
Even tho I have a whole-house surge protector. Just a habit
I can be in another state check on the house, pull live lighting data from an internet site I use. Call the house and tell the kids...Lort jeebus yall unplug my 55” hitachi and shut down both heat pumps 😃
As I once told a young feller who was going to buy a suppressor for his computer, lightning jumps across miles of sky; it can jump over your surge suppressor.
Opening the mains and all the breakers to stuff outside might help, but since many strikes are top-down, like the one that hit my father’s house, nothing is sure-fire. The one that got him came through an ungrounded VHF antenna (what was he thinking!?!), blew out drywall here and there following the house wiring, trashed his PC, the VHF set, and his furnace controller, plus various other oddments here and there.
My strike hit the housing for my well, a pretty dang good ground, and still blew up the pump controller 150’ away in my basement, $140 as compared to the $8k my father’s hit caused.
Your setup sounds entertaining at least. Hope Alexa doesn’t hack it.
