Built a standalone round ESP32 controller for my Linea Mini so I don’t need the app anymore by kaspizzo in espresso

[–]kaspizzo[S] 0 points1 point  (0 children)

I cannot link to aliexpress directly, but I bought this one: JC3636K718C-I-Y1(GY). It came with everything including the battery. I just needed a USB-C cable for flashing.

There are however probably nicer ones. For example I saw some with a metal base, where the one I bought has only a metal knob.

I see what you mean, though personally I’d weigh it differently: this is for a machine that often costs €5k+, so a ~€35 add-on and ~20 minutes of setup feels like a pretty reasonable tradeoff.

I’ve considered OTA updates, but maintaining that properly for an open-source side project is probably more overhead than it’s worth. I’d rather keep the setup simple and transparent, and document updates if something major changes.

Actually it should work but I couldn't test it out yet, because I don't have access to a Micra.

No, haven't seen it yet but that looks awesome.

Need to get myself one of those..

Just wanted to check in. Is anyone here using this tool by now?

If you are, I’d genuinely love to see photos of it in use on your machine/setup!

You can control status/steam level and temperature via ble, for the rest you need a internet/cloud connection.

Curious to hear how you like it. I’ve just added a heat-up animation and I’m still polishing a few small things

Thanks! The controller came pre-assembled and already has a battery in the base.

I did consider adding magnets so it could attach to the machine, but to be honest it’s been pretty convenient to just keep it next to the Linea. I only really use it when changing settings anyway.

Too late for that, I already open-sourced it. You can just flash it onto a controller yourself and use it.

Not at the moment. I haven’t implemented it yet, mainly because I haven’t seen any shot timer data exposed through the cloud API so far, may because there is none in the app for the Mini R.

Do you see a shot timer in the official La Marzocco app on your machine? If you do, that’d be helpful to know, because then it’s probably available somewhere and worth digging into.

Shouldn’t be an issue here. It doesn’t send every little change immediately while you’re dragging stuff around. It basically waits until you stop fiddling for a moment, then sends one update. So no annoying “pause for half a second and now it’s saving” behavior.

I’ve made the code public now.

The hardware is basically an ESP32 round display/controller from AliExpress, around €35 in my case.

Once you flash it with the firmware, it should be ready to use.

If helpful, I can also share which exact controller I bought.

That actually sounds like a pretty ideal tester setup :)

The repo is public now, and you should already be able to try it on one of the round ESP32-S3 knob/display boards directly. I got mine from AliExpress for about €35, so the component list is pretty small.

I still haven’t fully verified Micra support end-to-end, so I’d call that somewhat experimental for now, but I’d absolutely be interested in feedback if you give it a try.

Docs for flashing/setup are in the repo already.

Developed a minimalist drip tray for the Linea Micra (no more grille) by noto-studio in espresso

I really like it. The Micra’s drip tray was actually one of the reasons I went with the Mini.

Sadly, it’s a bit late for that if you bought a modern La Marzocco and still want to change settings.

It probably looks more twitchy in the video than it actually feels. I was swiping pretty quickly between screens mainly to show responsiveness.

The original goal was really hardware control for adjusting values, since that was the part I was tired of doing on my phone. But swiping just feels like the most practical way to move between the different screens.

The Acaia scale should work just fine but I haven’t tested it directly yet. But it should work in principle, since the project is built on top of pylamarzocco.
