A Belgian P1 meter publishes two UNSIGNED registers, not one signed figure. Until now the add-on asked the installer to bridge that gap with a template sensor, which put the sign convention of the whole control loop in a text box. This moves it into the EMS: net = import - export, derived once, in one place, with a test that fails if anyone inverts it. Two transports behind one contract, chosen by `meter_source`: the HA WebSocket subscribing to the DSMR integration's entities, and MQTT on a configurable topic. Everything downstream reads P1Ingest, so switching is a config edit. `meter_source: off` is the default and keeps the existing meter_entity path, so no installed system changes until it opts in. The other half is the timestamp. Every accepted sample is stamped at ingest with a monotonic clock, `meter_max_age_s` is applied to it, and the age is published as sensor.p1_sample_age_s for the ESP32's stale-input watchdog. That entity is recomputed against the clock every second rather than only when a telegram lands, because HA pushes state only on change: a meter frozen at a constant reading emits nothing and looks, to anything watching the value, exactly like a meter that has died. The age tells them apart. Deliberately absent: any fallback to an inverter-side power figure. The inverter's own AC power correlates 0.998 with battery power and 0.09 with the real meter, so failing over to it means regulating against your own output. A gap stays a gap - a reconnect emits no synthetic sample, and a rejected telegram never resolves to 0 W or refreshes the timestamp. Quarter-hour averages are time-weighted over clock-aligned blocks rather than a mean of samples, so a cadence change cannot bias the capacity-tariff figure, and only offtake is accumulated so a quarter of pure export averages to 0 kW. Per-phase import is kept separately: on an unbalanced three-phase load the phase sum and the connection net are different numbers, and only one of them is billed. test_p1.py: 99 checks, runnable with a bare interpreter and no meter. Includes an end-to-end run of the HA transport against a fake Home Assistant websocket. Stacked on SAFETY-04; nothing here touches control.py.
