Home Automation on RaspberryPi with Your Chickens!
summary
A Raspberry Pi Zero running Java 11 with p4j and Spring Boot controls a backyard chicken coop: GPIO drives a DC motor to open/close the door, relays switch a 12V lamp, a camera sends an email when the door opens, and a speaker plays music. The system consumes about 100 mA and is powered by solar panels (~50 W in summer) plus a €100–150 charge controller and 12V battery; lead batteries struggled in winter and were replaced by lithium to improve reliability, though very cold months required an external power extension.
