Pimoroni Automation pHAT
Best compact controller for DIY home automation and monitoring projects.
This compact interface turns a tiny computer into a robust command center for your home or garden. By packing relays and high-voltage inputs onto a single board, it sacrifices raw GPIO flexibility for a plug-and-play solution that makes automating lights, pumps, and sensors remarkably straightforward.
