EV charge detection - PilotWatt

PilotWatt can detect EV charging by monitoring grid import from FoxESS during your Intelligent Octopus cheap window. No Hypervolt or vehicle API is required.

Alpha status: Detection still runs in the background (daily cron + Settings toggle), but Home / History EV cards are hidden until direct charger integration ships. Re-enable in product when Hypervolt support lands.

How it works

A daily job runs at 06:00 UTC for users with EV tracking enabled
PilotWatt compares import power to your household baseline overnight (default baseline 0.3 kW; charge threshold 1 kW net)
Sustained import above threshold → logged as a charge session (start, duration, kWh, estimated cost) in Neon

What you see today
