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

How it works

  1. A daily job runs at 06:00 UTC (and can be triggered after scheduler activity)
  2. PilotWatt compares import power to your household baseline overnight
  3. Sustained import above threshold → logged as a charge session (start, duration, kWh, estimated cost)
