Sunsynk & octopus intelligent integration

Hi everyone, I’m looking for some advice on integrating my solar battery system with the Octopus Intelligent Go tariff.

I’m using a Sunsynk inverter with batteries, along with a MyEnergi Zappi charger. I’ve got Solar Assistant integrated with Home Assistant via MQTT, and I’ve also installed the solarsynkv3 add-on to access Sunsynk sensor data.

The Octopus integration is working well, and the Intelligent Dispatch sensor is reporting correctly. What I’d like to achieve is:

  • Preventing my batteries from discharging during allocated cheap-rate slots that fall outside the standard 23:30–05:30 window.
  • Ideally, I’d also like the batteries to charge during any allocated cheap slots, regardless of the time.

If anyone has tackled a similar setup or has suggestions for the best way to handle this, I’d really appreciate your input!
