PilotWatt connects your FoxESS solar battery to your Octopus Agile export tariff and helps you earn more without watching half-hourly rates all day. It:
  1. Shows what’s happening now — plain-English status on the home screen (exporting, saving battery for tonight’s window, charging on cheap rates, and so on).
  2. Suggests tonight’s best opportunity — export, store, or charge EV, with a reason and estimated saving.
  3. Schedules your inverter — once per day after Octopus publishes tomorrow’s rates, PilotWatt can push a FoxESS mode schedule for export peaks and overnight charging.

Who is this for?

  • You have a FoxESS inverter and battery
  • You’re on Octopus Agile Outgoing (variable export), not a fixed SEG rate
  • You want optimisation without living in three different apps
  • Optional: Intelligent Octopus import for cheap overnight battery/EV charging

What PilotWatt is not

  • Not a replacement for the FoxESS or Octopus apps
  • Not grid-import optimisation (export-focused today)
  • Not direct EV charger control yet (EV sessions are inferred from grid import)

Requirements

Check hardware and tariff compatibility before connecting.
