A fourth meter_source, `homewizard_local`, polling a HomeWizard P1's own local API (GET /api/v1/data) instead of watching an HA entity. The point is the age sensor. sensor.p1_sample_age_s is FW-01's watchdog input, and on every transport we had it measured "time since the value CHANGED", not "time since the meter REPORTED". Home Assistant offers nothing better: a repeated reading emits no state_changed, advances last_reported on neither serialiser, and state_reported cannot be subscribed to at all. Measured twice - 70 s of a frozen meter on the ENV-01 rig, and ten repeated readings against the live house. Our own capture of this house's meter goes 42.2 s and 97.0 s between changes, both past the default meter_max_age_s of 30, so the age sensor would have commanded 0 W on a perfectly healthy meter. Here every HTTP response is an arrival. The meter answered, now, with its current reading; whether the number moved is not consulted. Five identical readings are five arrivals. Reuses TEL-01's pipeline rather than restructuring it: same split_signed sign convention as ha_signed, same make_sample, same ingest stamping, meter_max_age_s, clock-recomputed age, plausibility bounds and the §20 unsigned-decode rejection. A failed or timed-out poll submits nothing, so it is a missing reading - never 0 W - and does not reset the age. meter_poll_s (default 5 s, the meter's own rate) is checked against meter_max_age_s once at startup, like the ha_signed entity ids. ⚠️ An arrival stamp cannot see a FROZEN meter, and no arrival detector can - one answering 200 OK with a stale number is arriving. The local API does expose what HA never had (the total_power_*_kwh registers stop advancing) and the transport tracks it as `unchanged_s`, but it is deliberately not folded into the age and not thresholded: this controller regulates grid toward ~0 W, and at a converged -10 W the export register needs six minutes to move by its 1 Wh resolution while the power figure legitimately repeats. Thresholding that would rebuild the false-trip limit cycle at the exact operating point we aim for. test_p1.py 179 -> 236 checks. Still defaults to off.
