Keurig ESPHome UART Bridge
(thelemmy.club)
Ever wanted to control a Keurig (K-Supreme, others may be possible with YOUR help! :D) via Home Assistant?
Well now ya can!!...if you solder in an ESP32 and run ESPHome on it to essentially turn it into a wireless UART bridge :)
Worked with Claude (sorry if that's not cool...feel free to ignore) to RE the J2 port on a K-Smart and a K-Supreme (had the K-Smart first before moving to a K-Supreme because I accidentally tore a PCB trace) and get the brewer to both send and receive useful information over ESPHome to Home Assistant!

Enjoy!! :D
I went through two K-Supreme machines that both failed in under a year. Eventually I ditched Keurig and their planet-killing K-Cups and started making pour over iced coffees that taste far better than anything a Keurig can make.
Yeah I originally got one when I moved out of my parents since I was living on my own. Big fan of the reusable pods that I can fill myself! Cleaning is a minor chore but worth it, imo. Never had one die of natural causes yet, but from the research I did on eBay, boards are pretty cheap and they're fairly simple machines to teardown. This mixed with my new-found knowledge of the software makes me (perhaps naively) think I can keep mine running for a while (provided I don't hold the soldering iron in one place too long :P)
