>The ESP chips are barely power efficient enough to run on battery with C. Incorrect, Esp32-s3 uses 8 micro amps in deep sleep.

  8uA is still large compared to some other options. I work on medical implants that average 15uA while actively sensing biological signals 24hr/day. This includes the analog front end hardware to condition the signals as well. 8uA of deep sleep current would be a non starter.
