Measurement method: three TP-Link EP25 metering outlets record true-RMS line voltage once per second on both 120 V legs of the split-phase service. A Tesla Wall Connector supplies the 240 V line-to-line reference and grid frequency, which is independent of the neutral. A Ting (Whisker) sensor on Leg A samples far faster than 1 Hz and retains the lowest and highest voltage it sees, so it resolves brief excursions that a 1 s RMS average necessarily flattens in both directions. Where the two disagree, the Ting figure is the closer estimate of the real extreme.
What is listed: any reading below 114 V (the ANSI C84.1 Range A lower limit) and any reading above 127 V (the Range B upper limit) at 120 V nominal. Undervoltage dims and stalls equipment; sustained overvoltage damages it, so both are reported.
36,779 samples logged today across 87 retained detail files.
Also recorded but not listed individually: 32 brief high readings on a 120 V branch meter, peaking at 127.4 V. These are held back for two reasons: readings between 126 V and 127 V are inside ANSI Range B, which the standard tolerates as occasional; and none of them were confirmed by the neutral-independent 240 V line-to-line reference, which never left its limits. They are reported as a count so that nothing is hidden, not because they are being claimed.

The legs differed by more than the tracking threshold, but neither fell far enough below its calm baseline or below the ANSI Range A limit to count as a sag. Normal load imbalance looks like this.

Labels describe the simultaneous meter pattern. They do not assert a confirmed physical cause; that determination belongs to the utility or electrician after inspecting the service.
