Earth Notes: On Website Technicals (2026-03)

An array of stats is captured around each EOM (End of Month). The process starts with meter readings taken nominally ~18:00 local time of the last day of the month, after any evening meal has been cooked (and eaten). First thing in the morning of the first of the next month HDD and Enphase monthly stats are captured. Then in the hour after noon UTC, when there is most likely to be some incoming sunshine, cron jobs on the main and heat-battery RPis capture (often compressed) monthly versions of various logs.

Those jobs were both running nearly at the end of the hour. I moved the smaller task (on pekoe for the Thermino heat battery) earlier a little so that manually committing that data to SVN and pulling it out elsewhere can be separated from the main server RPi work somewhat.
