A very simple trick to get around this is to simply hook a cheap non smart thermostat in parallel with the nest and set the air conditioner temperature one degree higher than you normally prefer. This way, you get the benefit of the cheaper power and you can still use the Nest's remote functionality. Personally, I won't use any "smart" device at my home.

REMEMBER

Texas' power issues have LITERALLY NOTHING to do with the fault of the infrastructure or the traditional power stations. They are PURELY due to jewden's forced, unconstitutional federalization of TX's power grid and forcing the use of (((Green Energy))) systems which aren't even capable of keeping a single fucking LED on.

What did they think was going to happen?

Yes, let's increase peak demand so we all have to pay higher electric bills due to requiring extra generators that just turn on for a few hours a day.
