Network-connected headless devices (e.g. Raspberry Pis with no displays) are often difficult to connect to over WiFi. Static IP addresses can be laborious to configure and, when on congested networks, address conflicts often arise. DHCP solves those problems, but there’s no easy way to know what IP address a device has been given by a router.
HereIAm provides an all-in-one network status reporting solution to address this problem. A tiny client Python script reports the network status, including IP address and WiFi signal strength, to a Node server. A React web app then connects to this server (using WebSockets for live updating) and displays the reported device information.
The following instructions will configure a Linux-based machine to report its network status upon connecting to any network. This (hopefully) ensures that the server will always be up-to-date.
-
Clone this repo (
git clone https://github.com/kylecombes/HereIAm.git). -
Install the dependencies with
sudo -H pip3 install -r hereiam/client/requirements.txt. -
Create a new plaintext file with
sudo nano /etc/network/if-up.d/hereiam. In it, place the following (inserting the correct URL and path to main.py):#!/bin/bash /usr/bin/python3 ~/hereiam/client/main.py --server <SERVER_URL> --config ~/.config/hereiam -
Make the file executable with
sudo chmod +x /etc/network/if-up.d/hereiam. -
Test the file by running
/etc/network/if-up.d/hereiam. The device should appear on the server.
