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

Hey, even if people don't approve of AI software (or baby-killing village-starving Nestle), turning something open source local-controlled instead of cloud SaaS locked down bullshit is always a good cause!

Haha besides the classic 'what if...?' that was my thought as well! :)
