# jura-coffee-machine
## Tech
`jura-e65-coffee-machine.txt` lists some technical data (reverse engineered years ago) and `jura-e65-circuit-board.jpg` shows PCB photos of the Jura Impressa E65 coffee machine.
## ESP8266 / Arduino
`cmd2jura.ino` is an HTTP gateway for the (serial) Jura service port. It offers a minimal web interface available via `http://jura/` and exposes its POST API like this:
```
user@workstation:~$ curl -d 'AN:01' http://jura/api
ok:
user@workstation:~$ curl -d 'TY:' http://jura/api
ty:E30 MASK 3
user@workstation:~$ curl -d 'RT:10' http://jura/api
rt:33DA01B1000C0640AA1116B301180000000000001E02007100150000000009D5
user@workstation:~$
```
It uses [WiFiManager](https://github.com/tzapu/WiFiManager) to setup WiFi, so you have to connect to the `JURA` WLAN AP with your mobile phone first.
I suggest to use the [Adafruit HUZZAH ESP8266 Breakout](https://www.adafruit.com/product/2471) or the [Wemos D1 mini](https://www.wemos.cc/product/d1-mini.html) as a hardware basis. Both are super-easy to setup and you have your gateway up and running within 10 minutes.
For [some coffee machine models](https://github.com/hn/jura-coffee-machine/issues/1), you might need to add
an [3V3/5V level shifter](https://raw.githubusercontent.com/ryanalden/esphome-jura-component/master/images/connection-diagram.png).
## Perl
`cmd2jura.pl` interfaces the coffee machine with the Raspberry Pi (indeed it should work with any device having a serial port and Perl). Example output:
```
root@raspberrypi:~# ./cmd2jura.pl AN:01
ok:
root@raspberrypi:~# ./cmd2jura.pl TY:
ty:E30 MASK 3
root@raspberrypi:~# ./cmd2jura.pl RT:10
rt:33DA01B1000C0640AA1116B301180000000000001E02007100150000000009D5
root@raspberrypi:~#
```
