Bernard is a Rust tool for presence detection in your home network.
It uses a mapping of MAC addresses to labels to accomplish that. Actually it parses the output of nmap scans, so the nmap tool is required to be installed.
Could be used to setup home automation etc.
Inspired by home assistent and written to learn more about the Rust programming language.
