Intelligent Battery Optimisation · GivEnergy + Octopus Agile

Your battery can't see tomorrow's prices, zerocore can

Your GivEnergy system is working hard. But without knowing tomorrow's Agile prices, the solar forecast, and your household pattern — it's just guessing. zerocore builds a new optimised plan every single day. Automatically. You never touch it.

The Problem

You're leaving money on the table.

Your battery came with basic controls. A schedule. Maybe an overnight charge timer. But it has no idea what the grid will need tomorrow.

📉
Export prices move every 30 minutes
Octopus Agile Outgoing can pay 5p at midday and 25p at 6pm. Your battery doesn't know this — it exports whenever you told it to, weeks ago.
☁️
Weather changes everything
A sunny day means your battery will refill from solar — drain it for morning export. A cloudy day means hold onto every kWh. Your battery can't see the forecast.
🚗
Your EV charger competes with your battery
When Octopus dispatches your EV to charge, your battery tries to power it — wasting stored energy at a loss. Nobody coordinates this automatically.
⚡
One wrong setting = expensive imports
If your battery runs flat at 7pm, you're buying electricity at 24p/kWh until cheap rate. A single miscalculation costs more than a month's subscription.
How It Works

A complete plan, every single day.

At 16:10 each afternoon, zerocore fetches tomorrow's Agile prices, your solar forecast, the weather, and your household patterns — then builds and executes a full day plan. You never make a decision.

16:10
PLAN
Tomorrow's Agile prices arrive. zerocore builds the plan.
Charge overnight to 78% (good solar forecast). Morning export at 9p. Evening export at 22p. 24% reserve for house until cheap rate.
23:30
CHARGE
Cheap rate starts. Battery charges from grid.
Charging at 7p/kWh — saving 22p vs peak rate
06:05
REFRESH
Fresh solar forecast arrives. Plan updated if needed.
Slightly less sun expected — bumps evening battery reserve from 24% to 27%.
06:30
EXPORT
Morning export begins. Battery discharges to grid.
Earning 9.2p/kWh during breakfast peak
08:00
HOLD
Morning export ends at calculated floor. Battery holds for solar.
Solar generation will charge the battery for free during the day.
16:00
EXPORT
Evening export begins. Peak grid demand.
Earning 21p/kWh — the most valuable window of the day
18:30
HOLD
Battery reserve reached. Export stops. House runs on battery.
Exact reserve calculated from your household consumption profile — no guessing.
23:30
CHARGE
Cheap rate. Cycle repeats.
Without zerocore: you'd have exported at random prices and imported at 24p when it ran flat.

Features

Intelligence that runs in the background.

Every part of zerocore is built to work without you — from morning to midnight, across every slot, across every weather pattern.

🧠
Fully Autonomous Day Planning
Runs twice daily. Fetches Agile prices, solar forecast, weather. Builds a complete time-blocked plan and pushes it to your inverter. No user input, ever.
📈
Per-Slot Export Optimisation
When the battery can't cover every export slot, zerocore skips the cheap ones and concentrates on the most profitable. Every decision is price-aware.
🔋
Dynamic Battery Reserve
Calculates the exact battery reserve needed to power your house from end of evening export until cheap rate — based on your actual consumption patterns, temperature-adjusted.
☀️
Adaptive Solar Strategy
High solar day: DC capture mode. Moderate solar: solar charge mode. Automatically selected from Solcast forecast. No seasonal switching needed.
🚗
EV-Aware Coordination
Integrates with Hypervolt + Octopus Intelligent Go via websocket. Suspends battery during EV dispatch. Pauses EV charging during high-value export slots.
📊
Live Dashboard & Savings Tracking
Real-time telemetry, today's plan with price colour-coding, historical views, export earnings, import cost breakdown. PWA — works on your phone.
Why ZEROCORE

Not a scheduler. An optimiser.

Most battery tools ask you to set rules. zerocore makes the decisions — every day, automatically, based on what the grid actually needs tomorrow.

Proven in Production
"I built this for my own house — a GivEnergy system on Octopus Agile. It's been running autonomously since March 2026, earning £2.98 a day on average. Every line of code was written to solve a problem I had myself."
