Fanbuddy is a non-destructive addon for the Sunlu S2 Filament Dryer to help extract humidity.
A D1 MiniPro is placed with other electronics in a 3d-printed case. The Arduino Code sends humidity and temperature data to a MQTT Server. The fan can also be turned on and off via MQTT which enables it for Home-Assistant Automations based on the sensor data.
This is the home for the arduino code and the home-assistant entities.
