Once connected

A clearer view, without replacing the apps you use.

Connect one account or several. Wattlas is the independent layer that helps the different parts of your home energy setup make sense together.

Follow the flow

See solar, battery, grid and EV energy in the same picture where compatible accounts provide the data.

Put usage in context

Bring a compatible tariff into the view to understand what a day of energy really cost.

Keep control where it belongs

Wattlas reads data only. Device settings, charging schedules and payments remain with the services you already trust.
