 1 | # MBusReader
 2 | This package uses Node.js to read base64 encoded mbus packages. It uses MBusParser to parse the received messages.
 3 | 
 4 | ## Disclaimer
 5 | This project is only developed as an example and may break at any time. (Tested on a Raspberry Pi 3)
 6 | 
 7 | ## Pre-Reqs
 8 | * Connect Oss-brikken to available USB Port
 9 | * Update to correct port in mbusreader.js
10 | * node, npm, and git installed
11 | 
12 | ## Get started
13 | ```bash
14 | git clone https://github.com/ossno/mbusreader
15 | cd mbusreader
16 | npm install
17 | node mbusreader.js
18 | ```
