GivEnergy entered administration on 9 April 2026. Warranties are void. Cloud support is uncertain. Your hardware is fine — your software shouldn't be at risk too.

§01/The Problem

Your battery is fine. Their business wasn't.

GivEnergy had around 35% of the UK home battery market. The app still runs today — but it's operated by a separate company with an uncertain future, and your battery can't see tomorrow's grid either way.

◈ RISK · CLOUD
No one is guaranteeing the cloud
Firmware updates, API continuity, long-term support — all uncertain. If your battery management depends on their servers, you're one outage away from losing visibility and control.
◈ RISK · PRICING
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.
◈ RISK · WEATHER
Weather changes everything
Sunny day: drain the battery for morning export. Cloudy day: hold every kWh. Your battery can't see the forecast. Your old app didn't, either.
◈ RISK · COST
One wrong setting = expensive imports
Battery runs flat at 7pm, you're buying at 24p/kWh until cheap rate. A single miscalculation costs more than a year of ZeroCore remote access.
§02/The Solution

Local-first control. Your home, your data.

ZeroCore Pi is a small device that installs on your home network and talks directly to your GivEnergy inverter — no cloud middleman required. It reads real-time data, builds a full daily plan from Agile prices and solar forecast, and gives you a live dashboard from any device on your network. Everything runs on hardware in your home.

[ 01 ]
Cloud-free
Direct local Modbus connection to your inverter. No dependency on GivEnergy's servers — if they go dark tomorrow, your system doesn't notice.
[ 02 ]
Agile-ready
Octopus Agile Import & Outgoing. Saving Sessions. Free Electricity events. Daily plan rebuilt from tomorrow's prices at 16:10.
[ 03 ]
Yours forever
One-off £190 hardware. First year of remote access included. Then £20/year — or run it locally, free, forever.
§03/The Device

Smart hardware, honestly explained.

ZeroCore Pi is built around a Raspberry Pi 4 — a proven, widely-supported single-board computer used in millions of homes and businesses worldwide. We flash it with our energy management software, pre-configure it for GivEnergy, and ship it ready to plug in. If you know what a Pi is, you'll appreciate the choice. If you don't, all that matters is: it's small, silent, reliable, and it just works.

§04/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 on your Pi. Refreshes at 06:05. You never make a decision.

◉ PLAN · 2026-04-19 — example day 24h cycle
16:10
PLAN
Tomorrow's Agile prices arrive. ZeroCore builds the plan.
Charge overnight to 78% · 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 reserve. Battery holds for solar.
Solar generation will refill 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's 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.
§05/The Dashboard

Everything at a glance. From any device on your network.

Live battery, solar, and grid telemetry. Today's plan with price colour-coding. Historical views. Export earnings. Import cost breakdown. It's a progressive web app — install it on your phone with one tap.

§06/Features

Everything the GivEnergy app did. And more.

A complete replacement for the features you relied on — and several the app never offered.

FN.01
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.
FN.02
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.
FN.03
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.
FN.04
Adaptive solar strategy
High solar day: DC capture mode. Moderate solar: solar charge mode. Automatically selected from Solcast forecast. No seasonal switching needed.
FN.05
EV-aware coordination
Integrates with Hypervolt + Octopus Intelligent Go via websocket. Suspends battery during EV dispatch. Pauses EV charging during high-value export slots.
FN.06
Saving Sessions & Free Electricity
Detects and responds to Octopus Saving Session dispatches and Free Electricity events automatically. Overrides your daily plan when it pays to.
FN.07
VPP override support
Full Axle Energy VPP membership support. Your Pi hands control to Axle during dispatch windows, then picks up where it left off.
FN.08
Push notifications
Session events, alerts, daily earnings summaries. Delivered via ZeroCore Cloud (included year 1, £20/yr after) or run fully local if you prefer.
FN.09
Firmware reset protection
GivEnergy firmware updates often wipe your schedule. ZeroCore rebuilds and reapplies your plan automatically — your settings never get lost.
§07/Comparison

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. And it doesn't vanish if a company does.

§08/Proven in Production

Built on a real home battery.

ZeroCore wasn't invented for the GivEnergy pivot. It's been running autonomously on the founder's own GivEnergy system since March 2026 — the Pi version packages that same software into hardware you can unbox and plug in.

"I built this for my own house — a GivEnergy 15kWh system on Octopus Agile. It's been running autonomously since March 2026, earning £2.98 a day on average. When GivEnergy went under, it didn't miss a beat. That's exactly why the Pi exists."
