ReaPrime (R1) is a gateway app to the next generation of interfaces for the DE1. An API first approach makes it help you focus on developing modern and sleek UIs, that are easy on the eyes as well as a delight to use.

To browse the REA API, start REA and then point your browser to localhost:4001.

The primary platform for ReaPrime is Android, as it runs on the tablet the DE1 ships with. Of course, R1 can run as a service in the background, neatly tucked out of the way, but still keeping a stable connection between your app and the DE1.

Currently, R1 supports the most basic of features, but enough to support the main workflows

• Query and set machine state (turn off/on, start espresso on machines without GHC, stop the shot)

• Set machine settings such as hot water temperature, steam temperature etc.

• Upload v2 json profiles to the machine (the ones de1app stores in profiles_v2)

• Exposed websockets for realtime shot updates and other values that might change frequently

• Tare the scale
• Exposed websocket for weight snapshots

• Felicita Arc
• Decent Scale
• Bookoo

REA features a plugin system, for dynamic expansion of the user experience. More details coming soon.

I'll skip through Flutter SDK install for now, google has all the answers.

For versioning purposes, a build script is included, that injects certain environment vars into the build process.
If you want to take advantage of that, make sure you run: ./flutter_with_commit.sh run

Have Colima installed. Then make build-arm

REA stands for "Reasonable Espresso App". Provided you use it with a Decent Espresso machine, it might help you brew a reasonably decent espresso.

Credit for the name and thanks for all the support, goes to @randomcoffeesnob.
Also thanks to @mimoja for the first Flutter app version.
