For diagnosis, not argument: labels describe the simultaneous meter pattern. They do not claim a confirmed physical cause; the timing, depth, corroboration, and duration are here to help the utility or electrician diagnose it.
Last 24 hours — 120 V legs plus Ting retained-low markers
Minimum-preserving detail for the selected range.
Grid frequency & 240V service — selected range
All-time daily range (min / max)
Out-of-range episodes
Each row is one continuous episode, not one sample — the logger writes a line every second while a meter is out of range, so a 13-minute sag used to appear as 800 “excursions”. Sags (below 114 V) are the ones that matter; swells above 126 V are listed separately and are not the flicker problem.

Classified diagnostic voltage events — observed pattern, not a confirmed cause
Graded by the evidence each event carries, not by whether a pattern name matched. Actionable means a meter left the ANSI Range A envelope (below 114 V, or 228 V line-to-line) or the legs split by 8 V or more; notable events are shown alongside. Ordinary load imbalance is filtered out. An event closes only after three consecutive recovered samples. Open the printable irregularity report → · simple one-page version for PG&E →

Ting retained-low markers
Ting can retain a brief low that its sampled line misses. Exact markers use Home Assistant's source timestamp; historical first-seen markers are labeled approximate.
