Since I haven’t found anything to handle ventilation using an attic fan (beyond just simple on/off) and on request from folks here is an app for the Smart Attic Fan Ventilator.

It turns the attic fan ventilation on/off based on internal and external conditions including looking at the sunlight on the roof, the temperature outside, inside and the target expected temperature.
It supports up to 3 operating schedules that can be configured.

If you have any feature requests please send it in.

TIP: If you don’t have a external light/temperature sensor install the Smart Weather Tile and Updater here. You can use this as your external light and temperature sensor. [RELEASE] Smart Weather Station Tile Updater - Fix Broken Modes

Best way to make an attic fan smart?

“Whole House Fan” sounds similar but it does not use the sunlight to help make decisions.
