r/gaggimate

I've been dialing in on a GaggiMate and wanted something that would look at my shots and tell me what to change — without pasting data into a chatbot every time. So I made crema: a small self-hosted service that runs on a Raspberry Pi (or any always-on computer) on the same network as the machine.

What it does:

- Automatically pulls new shots off the machine and parses the telemetry (pressure/flow/temp curves, channeling + puck-resistance diagnostics)

- Sends recent shots to Claude and gets back a 1–10 score plus concrete grind/dose/profile suggestions — grind advice in your grinder's own steps/clicks if you tell it what you run

- One click to draft a corrected profile, add your own taste notes ("came out sour, keep preinfusion short") and refine it, then push it back as a new [AI] profile — it never overwrites your originals, and it warns you explicitly if a draft would change your stop conditions

- A little web report you can also trigger on demand

It complements GaggiMate's own graphs and UI rather than replacing them — you still brew from the machine; crema adds the review layer on top. It's the hands-off counterpart to the excellent interactive gaggimate-mcp server (I vendored its .slog parser — full credit in the repo).

Free and open source (MIT). Fair warning: the reviewing runs on the paid Anthropic API — a few cents per shot, realistically a dollar or two a month, and nothing spends automatically until you turn it on.

Early days and very much a personal project — feedback and PRs welcome. Curious whether it's useful to anyone else running a GaggiMate.

I’ve had the E24 for 6 months and generally speaking it’s been pretty great for a fairly basic / cost effective set up. Shots are pretty good with the 9bar spring mod but I have some consistency issues.

I’m new to Gaggimate, don’t have a laptop to program so would I still benefit from this? Think the main thing I need is better temperature stability which I believe this would help with and being able to profile shots? (Once I learn how to!)

Any thoughts or advice would be much appreciated!

After much planning I completed my Gaggimate conversion and general upgrade of my 2010 Classic this evening.

Full list of changes:

- Removed and checked the boiler condition
- Removed and cleaned the dispersion block
- Installed Rancilio Silva steam wand
- Installed IMS shower screen
- Installed the Gaggimate Pro kit including the Alba tank light kit, GM custom drip tray and a Bookoo Themis mini
- Vinyl wrapped the machine

Overall I’m incredibly happy and proud of the results. I still feel I can do a better job on the cable routing and all the internals, but otherwise it’s everything I hoped it would be.

..and yeah, the coffee is fantastic ☺️

Any profiles I should be trying? I gravitate toward light naturals but am open to anything.

Just installed the Alba and finished my custom Acacia integrated drip tray!

With a bit more sweat than anticipated, and thanks to the amazing support of community at Discord, here we are, relearning how to brew good espressos with this coffee machine, that I already liked, and now I'm really enjoying. Some promising shots already!

As expected, no more temp surf nor spraying when I brew at 9 bars (standard EU spring is the 12 bars one), which is really cool in terms of consistency.

But now I have to dial again all my beans, and I am a bit lost. Are there any structured learning resources I could use? Or is it basically Discord? Any advice or hint you could share?

With a non-bluetooth Wacaco Exagram scale and bottomless IMS basket, I was used to start my dialling by adjusting grinder so as to have flow start around 5-6 seconds, adjusting time between 25-35 seconds, adjusting yield depending on the bean, taste, etc.

But now it is not easy to do that as standard 9 bar brew profiles I've used so far have an initial phase of adjusting pressure, with some minor dripping, then it gets a bit stuck, then incremental flow, etc.

So at the moment - I get I am now a beginner again with GM Pro in place and I'll hopefully learn - it is a bit complicated to try and get shots the traditional way, controlling ratios, times, yield, body, etc.

I've - by now - tweaked some standard profiles, brewing by output weight - I guess GM Pro estimates by flow? - and adjusting that profile value depending on what I get on my humble scale. So far so good, but I obviously want more from this setup.

How did you handle that transition? Did you have to change the basic approach? I've seen people are installing Bluetooth enabled scales, and brewing by weight, but I'm not sure if that is a need or just a nice to have gadget.

Thanks in advance!

Spent all day setting this up. Was careful with everything until the end. Accidentally bumped my screen onto my table while moving something around and when I went to test this was the result. So disheartening. Now just have to wait for the replacement screen in hopes I installed everything correctly.
