On a related note, I have been working on an app that helps determine the correct grinder setting when dialing in espresso. After logging two shots with the same setup (grinder, coffeee machine, basket etc), it then uses machine learning (and some other stuff that I am still improving) to predict the correct setting for your grinder based on the machine temperature, the weight of the shot etc.

Its far from perfect when it comes to predictions right now but I expect to have massive improvements over the coming weeks. For now it works ok as an espresso log at least.

I'm hoping after a few tweaks I can save people a lot of wasted coffee!

Me and the wife (en_GB - draw your own conclusions!) love a decent coffee but can't be arsed with too much wankery over it. We have owned a few kitchen built in units and I've messed with a couple of grinders and espresso pots in the past.

Wifey found a kitchen built in unit a few years ago and it is still doing the job, very nicely.

Let's face it, what you want is a decent coffee and you have to start from that point, not what sort of bump or grind (that's grindr).

I want a cup of coffee with: - Correct volume - sometimes a shot, mostly an "Americano" - I'm British don't you know - Correct temperature - it'll go really bitter if too hot. Too cold - ... it'll be cold. - Crema - A soft top is non negotiable - Flavour - Ingredients and temperature (mostly)

The unit we have now manages bean to cup quite reasonably, without any mensuration facilities. I have made coffee for several Italians and they were quite happy with the results.

Funnily enough I have built essentially the exact same thing in HomeAssistant. Shot collection is completely automated as I have a LM Linea Micra and Acaia Lunar scales (Both have integrations that use Bluetooth). You should consider support for bluetooth scales etc!

Missed chance to call it Grind Finr
