I’ve been working on a raspberry pi 0w based PID controller for my Gaggia. It’s working quite well. I think the SD card based installation flow could really help a lot of people who would otherwise need to flash an MCU. Currently it’s only doing PID temperature control. I’d like to benchmark model predictive control. I’d also like to do some of the more advanced features like pressure control, wire up a scale, and make a nice web UI.
