Is anyone here using Raspberry Pi as a PID? I'm in the middle of switching my system over from 110v to 220v and I'm seriously tossing around the idea of eliminating my control panel and PID's and replacing them with RaspberryPI and a touchscreen. Been researching it a bit now. There is now a prebuilt component from Adafruit that will allow me to use my quick connect RTD temp sensors. I've found a lot of nice programs that have been written to control it all. All the hardware is pretty economical. I also like the idea of it being web-based. This will give me the option of not even having to leave my recliner to brew!!
I also like the idea that I can expand it and store recipe profiles, so when I want a particular brew, I can open that file and all the temperatures are right there should I want to do a step mash. It will also allow me to control my pumps from it. I'll also be able to run a temp prob from my fermentation chamber and control that. I can easily preprogram it so that it will automatically raise/lower the temp at different stages during fermentation. It will keep a chart of the actual temps over the course of fermentation that I can later print out. All in all, it just sounds so needlessly and overly complicated that I would be stupid to not do it. Has anyone else here done anything similar?
