How are you using the forecast? Show your setup

The forecast is most useful when it drives something — an automation, a scheduling decision, a dashboard alert. I'm curious what people have built.
My main use case: the consumption forecast feeds into another app, which combines it with a solar production forecast to compute expected hourly surplus and automatically schedules deferrable loads (dishwasher, washing machine, heat pump DHW boost) in the best windows. The scenario API is useful for sanity-checking a candidate schedule: "if I run the washer at 14:00, what does total consumption look like?"
But you don't need the energy manager to get value — energy_forecast_tomorrow and the 3-hour block sensors work directly in HA automations. A simple threshold automation ("if surplus forecast for 13:00–15:00 > 1.5 kWh, start the dishwasher") goes a long way.
What are you doing with yours? Paste an automation, a dashboard card, or just describe the decision you're automating. Happy to help adapt the sensor setup for your use case.
