It offers a minimal web interface available via `http://jura/` and exposes its POST API like this:\n\n```\nuser@workstation:~$ curl -d 'AN:01' http://jura/api\nok:\nuser@workstation:~$ curl -d 'TY:' http://jura/api\nty:E30   MASK 3\nuser@workstation:~$ curl -d 'RT:10' http://jura/api\nrt:33DA01B1000C0640AA1116B301180000000000001E02007100150000000009D5\nuser@workstation:~$ \n```\n\nIt 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.\n\nI 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.\n\nFor [some coffee machine models](https://github.com/hn/jura-coffee-machine/issues/1), you might need to add\nan [3V3/5V level shifter](https://raw.githubusercontent.com/ryanalden/esphome-jura-component/master/images/connection-diagram.png).\n\n![ESP8266](https://github.com/hn/jura-coffee-machine/blob/master/jura-esp8266-interface.jpg \"Adafruit HUZZAH\")\n\n## Perl\n`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:\n\n```\nroot@raspberrypi:~# ./cmd2jura.pl AN:01\nok:\nroot@raspberrypi:~# ./cmd2jura.pl TY:\nty:E30   MASK 3\nroot@raspberrypi:~# ./cmd2jura.pl RT:10\nrt:33DA01B1000C0640AA1116B301180000000000001E02007100150000000009D5\nroot@raspberrypi:~# \n```\n\n![Raspberry](https://github.com/hn/jura-coffee-machine/blob/master/jura-raspberry-interface.jpg \"Raspberry Pi connection 9600-8N1\")\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhn%2Fjura-coffee-machine","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhn%2Fjura-coffee-machine","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhn%2Fjura-coffee-machine/lists"}
