For anyone interested in this sort of thing (like me), the Decent DE1 Espresso machine is a well-engineered, cafe quality, open-source machine that you can buy.
There is a small community working on various software apps around it. The machine is controlled through open BLE comms. All the control software AFAIK is OSS and tinkerable. The machine itself is top notch, and in my espresso-nerd opinion, beats anything on the market except in appearance and "analogeness".
So if you like espresso and hacking on software, check it out.
- asciimike 4y agoIs there a better guide than the app source code? I can't seem to wrap my head around the BLE comms aspect (e.g. how it integrates with scales or the Smart Espresso Profiler app).
- Hippocrates 4y agohttps://github.com/jeffsf/pyDE1 https://github.com/jeffsf/pyDE1 this is a pretty complete python implementation covering the BLE APIs including scales. It's way more approachable than the TCL Android app. Some more info on the protocol here: https://3.basecamp.com/3671212/buckets/7351439/documents/4994850262 https://3.basecamp.com/3671212/buckets/7351439/documents/499... I don't think there are any better "formal" docs.
