This morning i finished my first brew with craftbeerpi in a modified matho controller. I jumped in the deep in and tried out v2.2 straight off the bat which was probably a mistake but got through the brew and should still have very drinkable beer in a couple of weeks.
After around 4 years of using mathos controller it was quite nice easily inputting steps through my laptop. being able to see the exact times and graphs of your brewday is great for judging quick trips to the shops, kids sports, SWMBOs chores, etc. I haven't yet figured out how to login offsite, but that is definitely next on the list.
During todays brewday I felt it was missing a few bits and pieces which would make brewday a breeze such as ability to choose PWM % during boil, on/off hardware option in each step, hop timer (I used separate steps for hop additions today which worked but clunky), ability to change buzzer length or maybe just for hop additions, LCD or OLED integration to display step/temp/time and a chill step and alert when reaching desired temp. Uploading beersmith recipes would also be a fantastic feature but maybe asking too much?
Further expanding on the on/off hardware option in each step, this could open up a world of options. Solenoids for automatic filling and racking, depending on your setup it could turn it into a nearly fully automated system. I'm sure there's plenty more that i have missed but this would be a fantastic feature.
If i have missed anything please let me know, still very green with the system.
If anyone is interested on how i attached the pi to the controller i used one of these
