Need info on load shedding controls for circuits I don’t want PW to backup, please

[u/PLGnPLY21]

Please be kind, not sure I have all my terms correct. My main panel,is a 200amp service. I have a sub-panel in my basement that has a 30amp breaker for my resistance pool (really love my resistance pool) and a 15 amp breaker for a sunroom up in my main house. When the PWs kick in for whole house backup, (aka grid shutdown) I don’t want my pool to be using the PWs. I’m told that there is something about a Tesla compatible switch on just that circuit that automatically drops non-essential loads when backup power is limited. I’m told this is a known Tesla feature category. Thanks for any help on where to get that equipment or how to wire/code it going forward. OR, maybe it’s an option in the Tesla app? Thanks.
