Everything SunHarvest does, how to set it up and how to get the most out of your Powerwall. It covers the web app at sunharvest.net and the SunHarvest Android app.

SunHarvest connects to your Tesla Powerwall and does three things:

• It shows what your solar, battery and grid are doing now and did before.
• It controls the Powerwall from rules you write in plain English.
• If you switch it on, it plans the battery for you with an AI that works toward a goal you describe in your own words.

Monitoring and your own rules are free. The AI planner, the fast-refresh lane and the "what solar saved you" figures are the paid part. Every new account gets all of it free for 30 days.

What you will need

• A Tesla Powerwall and the Tesla account it is registered to.
• A browser, or an Android phone for the app.
• For AI mode only: your own account with an AI provider and its API key. SunHarvest never sends your data to an AI on its own account. It uses yours, on your quota, under your agreement with that provider. AI mode walks through each provider from scratch.

Just looking? Try the demo: it opens a made-up home you can click around, with every screen, rules and an AI plan, without an account or any hardware.
