The wifi thermometers are pretty cheap. Having a backup plan would be prudent too. A friend or two in another part of the city, whose power might not be interrupted?That’s quite a setup, definitely more advanced than “hope for the best” approach
I live in an apartment, so having a generator isn’t really an option.
Honestly, that’s the kind of setup that would let me sleep peacefully lol
In any event, Peter Magic's interview seemed to pretty much disprove the necessity of freezing, even when looking for years of storage. I just do it as an extra precaution.
