Keurig ESPHome UART Bridge (lemmy.world)

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

Fair enough, it's just that the whole point of these pod brewers is that they can make a cup of coffee from powered off state to finish in a literal minute so I hardly see the point. But "new gadget" is a reason I guess.
