Homebridge plugin for the bh1750 light sensor on a Raspberry Pi

Installation of other plugins

I assume that this Guide was followed, so your homebridge config file is under /var/homebridge and you used the systemd version. Create a folder called other_plugins in that hombridge folder and checkout this repository inside that newly created folder.

Now you want to alter the file you placed under /etc/default/homebridge accordingly

# Defaults / Configuration options for homebridge
# The following settings tells homebridge where to find the config.json file an$
#HOMEBRIDGE_OPTS=-U /var/homebridge
HOMEBRIDGE_OPTS=-U /var/homebridge -P /var/homebridge/other_plugins -D

# If you uncomment the following line, homebridge will log more
# You can display this via systemd's journalctl: journalctl -f -u homebridge
#DEBUG=*

You might need to run a systemctl command to update the config file. The system should inform you about the specific comand if you enter sudo service hombridge stop. After you have executed the suggested command you'll want to enter sudo service hombridge restart. Homebridge should now be aware of any additional plugins within the /var/hombridge/other_plugins folder.

Now run the following code to install the dependencies.

cd /var/hombridge/other_plugins/homebridge-bh1750
npm i

You can now add the configuration to your config.json

Wiring

You might want to google BH1750 and raspberry pi together. There are plenty of tutorials on how to wire these. You can see this guide here for instance.
