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!

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!

[–] peskywarrior@lemmy.world 5 points 2 days ago

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

I see a local integration, I upvote!

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.

[–] peskywarrior@lemmy.world 10 points 2 days ago (2 children)

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

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.

[–] ExcessShiv@lemmy.dbzer0.com 2 points 2 days ago

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.

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.

[–] peskywarrior@lemmy.world 4 points 2 days ago

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)
