The Automation page: two switches per layout
Automation is solarprod working while you sleep. For each saved layout there are two separate switches: a daily email with the forecast and action plan, and daily timer updates that put that plan on your inverter. You can have either, both or neither.
Daily email: the forecast, how it has moved, and the week's action plan
Subscribe and we run the forecast for that layout and email it at the hour you pick. Unless you change it, that is 1 am, so it is waiting in the morning.
- Send at, on each subscribed layout, sets the hour it goes out, in your local time.
- Forecast evolution: for each coming day, how the prediction has changed from one day to the next. Every number carries a plus-or-minus band, and you can watch the band tighten as the day gets closer.
- The next seven days as a strip, then the Action plan for those days: when to charge from the grid, when to hold, and when to export.
- Send test email sends one now so you can see what it looks like. Last delivered shows when the most recent one went out.
- Every email carries a one-click unsubscribe link. Unsubscribing stops the email and nothing else.
Daily timer updates: the plan runs on your inverter without you
Turn on daily updates and we set the plan's import and export windows up as timers on your inverter now, then rebuild them every morning from the latest forecast until you switch it off.
- It shows only when you have an inverter we can write to. A Tesla Powerwall, or a Deye whose account has control permission. Otherwise the row says Connect inverter for automation and links to your Account page.
- The rebuild runs at about 2 am, an hour after the email's usual 1 am send, and normally uses the very same plan. If fresh weather arrives in between, the timers get the newer plan; the email is never wrong, just a little older.
- Timers you made yourself are left exactly as they are. Only the timers marked From your plan are replaced.
- The same checks apply at 2 am as when you press the button: the brand must support timers, your account must hold control, and the inverter must not be driven by another schedule.
- While it is on, the row reads Updating daily, and names the inverter if you have more than one.
Turning it off: from the page, or from the email
Turn off daily updates stops the morning rebuild. The timers already on the inverter stay until you delete them on the Inverter control page, and your manual timers are never touched.
- The email footer has a second link, separate from unsubscribe, that stops the timer updates in one click. We send one email to confirm it happened, and never another.
- Because the two switches are separate, unsubscribing from the email does not stop the timers, and stopping the timers does not stop the email.
Paid feature: why there is a tier badge
Running a forecast for you every night costs compute and email, so the daily email is part of the paid plans. The page still shows the section on the free tier so you can see what it does.
- See plans and subscribe takes you to pricing. Once you are on a paid plan, every saved layout appears here with its own switches.
- No saved layouts yet? Create one in the calculator first; the page links you there.
