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!

Details here: https://github.com/gitman-101111/bye-keuri-ous

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!

I'm very pro home automation, but what problem does this actually solve? Like, you still need to be at the machine to make the coffee (put a cup there, put in the pod in this case), so remote brewing doesn't make sense.

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.

Personally, I 'stage' my machine the night before (I use one of the re-usable pods): pod in, lid closed, mug placed. Then, when I wake up/presence is detected in the kitchen, the machine 'wakes up', sets the brewer settings, and brews automatically.

It's stupid, but it's new and cool for me right now lol

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)

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

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.

That sounds so futuristic, and in a good way due to being completely local. Super cool. Also appreciate the mention of re-usabe pods.

Now, if only you could figure out how to have it make good coffee.*

*This is mostly intended as a joke, if you like the coffee it makes, great! Personally, I've only had bad, awful, bitter experiences with friend's Kuriegs, but hey, maybe there's a way to have them make good coffee as well that I'm not aware of. This does make we want to implement this with a bean-to-cup auto-brewer, but I'm thinking that'd be a helluva lot more complicated.
