Blueprint: solar-driven household with Home Assistant

A home that follows the sun instead of the clock

In a solar-driven Leafy Energy household, the combined effect of PV production, dynamic prices, and flexible loads determines how the home behaves. Home Assistant acts as the central conductor.

Architecture overview

• Leafy Energy integration – provides price and consumption data.
• Solar inverter integration – real-time production and daily curves.
• Home Assistant – automation rules, scenes, and UI.
• Target devices – heat pump, boiler, EV, white goods, and battery.

Core logic in this blueprint

1. During the day, appliances and boiler runs are preferentially scheduled in sunny hours.
2. When the price drops below a configured threshold, the battery is allowed to charge more aggressively.
3. When prices are high but the sun is shining, consumption is prioritised over export.
4. After sunset, the logic switches to a purely price-driven profile.

Home Assistant recommendations

• Use templates to create composite variables (for example “effective_price” = market price - solar benefit).
• Build blueprints that can easily be copied across Leafy demo environments.
• Offer a single “Leafy Solar” dashboard with cards for sun, price, battery and consumption.

This blueprint is excellent for trainings that should show Leafy Energy as more than a price feed: it becomes an orchestrator of sun, price and load.
