This only works when the device is connected to USB 😭 . Apparently, it disconnects the battery when going into deep sleep, and RTC attributes are probably cleared.

I think Larry found a solution for that: bitbank2/bb_epaper@2404ab6

I wonder how much it affects battery life in sleep mode.

Light sleep does affect battery life significantly as it's ~20 times more power consuming than deep sleep.

Just wondering though, the partition table does have spiffs, why can't we use it to store or cache some settings?
