Make your home battery follow your electricity plan.
Sundime is a local Autopilot for compatible Australian home batteries. The Sundime Gateway reads your electricity plan and the solar forecast, then decides when your battery charges, holds or exports.
How Sundime works
No two electricity plans are the same. Autopilot learns yours and works out your battery's day:
Learns your home
How and when your household actually uses power. Sharper every week it runs.
Reads your electricity plan
Your rates through the day, free periods and what you're paid to export.
Forecasts your solar
Weather-based forecasts of tomorrow's solar and what your home will use.
Calculates the battery plan
When to charge, hold or export — recalculated through the day as conditions change.
Runs in your home
It all runs on the Gateway in your home. If your internet drops, the plan keeps running.
Shows you what happened
What Autopilot did and why — and, once there's measured data, what it saved.
The ground rules
Local first
Decisions are made on the Gateway in your home, not in a data centre. We don't sell or mine your energy data.
You stay in control
Pause Autopilot from the app at any time. Every change is recorded and reversible. Sundime never touches the protected settings your installer commissioned.
Savings are measured
No dollar figure until there's measured data from your home. We don't guarantee savings — results depend on your home, battery, solar, plan and weather.
Private beta
A small group of Australian homes on GoodWe ESA batteries. More brands as each one is tested.
Who it's for right now
Homes with solar and a battery
Australian homes that already have both, and want more out of them.

People who'd rather not micromanage
Owners who want the battery working harder without spreadsheets or daily fiddling.
Want your battery to work smarter?
Missing the cheap or free hours?
Your plan has them. Your battery may not use them.
Running down too early?
A daily plan holds energy back for when your home needs it.
Tired of changing settings?
Sundime replans every day. No spreadsheets, no tinkering.
FAQ
Is Sundime AI?
Yes. It uses local machine learning and optimisation to learn your home's energy patterns, forecast solar and calculate a battery plan. We call it Autopilot.
Does Sundime guarantee savings?
No. Savings depend on your home, battery, solar, electricity plan, weather and setup. Sundime only shows dollar savings once it has measured data from your home.
Does it work with my battery?
Works with GoodWe ESA batteries today. More brands to follow. Dual-phase GoodWe ESA homes are assessed individually. See how we check your home.
What data leaves my home?
Decisions are made on the Gateway in your home. It checks in with our Australian-hosted cloud for software updates, plan and rate data, and a health heartbeat. With remote access on, energy and status data passes through a secure Australian relay so your app can reach home. We don't sell or mine your energy data — full detail in our Privacy Policy.
Can I pause it?
Yes, from the app at any time. Your system goes back to behaving as it did before, and every change is recorded and reversible.
Why is Sundime in private beta?
One tested battery integration first, then more brands as each is tested. We'll publish pricing before anyone pays anything.
Do I need an electrician to install it?
We guide accepted beta homes through connecting the Gateway to the battery. If your existing installation needs changes, your installer may need to help.
What can Sundime change?
A small set of everyday battery controls — charge times, and how much energy to hold for later. It cannot change the protected setup your installer completed.
How is this different from my inverter's app?
Your manufacturer's app shows the system and its settings. Sundime adds a daily plan built around your prices, expected solar and normal home use. Keep using it as you do now.
