[shampto3]

UPDATE: I followed the instructions in https://news.ycombinator.com/item?id=35986375 for each of the nodes and it appears to have solved the problem, at least for now. I will keep an eye on them to make sure they don't die again.

The frustrating part was that my home assistant raspberry pi was hardwired into one of the nodes that died, so my automation to change my thermostat wasn't working and it was stuck on a setting that I normally only set for one hour in the day. Obviously I could change it manually, but I didn't realize that it hadn't changed until it had been like 5 hours.
