What Sundime is

The Sundime Gateway is a small device in your home that runs a supported home battery on a daily plan: charging on cheap and solar energy, then powering your home through expensive periods. The Sundime app is how you see that plan and change it. GoodWe ESA is the first supported system.

Getting help

• From the app. Settings → Help & support, then Email support. Your mail app opens with the details we'd ask for anyway.
• By email. support@sundime.com.au. Tell us what you saw and roughly when.
• Let us look. Settings → Help & support → Remote support lets the Sundime team connect to your Gateway to look into a problem. It is off unless you turn it on.

Common battery questions

• A problem, or a plan that no longer fits?
• Battery waiting instead of charging?
• Still buying power with charge left?

Battery or inverter faults

Sundime plans a working battery. It doesn't repair hardware or replace your system's own support. For a fault, an error on the inverter, or anything physical, use the support that came with your battery.
