Home assistant add-on: changedetection.io

I maintain this and other Home Assistant add-ons in my free time: keeping up with upstream changes, HA changes, and testing on real hardware takes a lot of time (and some money). I use around 5-10 of my >110 addons so regularly I install test machines (and purchase some test services such as vpn) that I don't use myself to troubleshoot and improve the addons

If this add-on saves you time or makes your setup easier, I would be very grateful for your support!

About

Changedetection.io provides free, open-source web page monitoring, notification and change detection.

This addon is based on the docker image from linuxserver.io.

Configuration

Use the add-on env_vars option to pass extra environment variables (uppercase or lowercase names). See https://github.com/alexbelgium/hassio-addons/wiki/Add-Environment-variables-to-your-Addon-2 for details.

Main app

Web UI can be found at <your-ip>:5000, also accessible from the add-on page or through the sidebar using Ingress.

Sidebar shortcut

You can add a shortcut pointing to your Changedetection.io instance with the following steps:

1. Go to ⚙ Settings > Dashboards
2. Click ➕ Add Dashboard at the bottom corner
3. Select the Webpage option, and paste the Web UI URL you got from the add-on page.
4. Fill in the title for the sidebar item, an icon (suggestion: mdi:vector-difference), and a relative URL for that panel (e.g. change-detection). Lastly, confirm it.

Options

Option	Type	Default	Description
PGID	int	0	Group ID for file permissions
PUID	int	0	User ID for file permissions
TZ	str		Timezone (e.g., Europe/London)
BASE_URL	str		Full URL when running behind reverse proxy
PLAYWRIGHT_DRIVER_URL	str		Playwright driver WebSocket URL
TIMEOUT	int	60000	Request timeout in milliseconds

Example Configuration

PGID: 0
PUID: 0
TZ: "Europe/London"
BASE_URL: "https://changedetection.mydomain.com"
PLAYWRIGHT_DRIVER_URL: "ws://db21ed7f-browserless-chrome:3000/chromium?headless=true&stealth=true&blockAds=true"
TIMEOUT: 60000

Connect to browserless Chrome (from @RhysMcW)

Install and start the Browserless Chrome add-on, then use the PLAYWRIGHT_DRIVER_URL option to connect to it. This option must be filled with the Browserless Chrome URL: "ws://db21ed7f-browserless-chrome:3000/chromium?headless=true&stealth=true&blockAds=true"

The db21ed7f-browserless-chrome hostname is displayed in the UI, on the Browserless Chromium addon page:

Then restart the Changedetection.io add-on - after that you can use the browser options in Changedetection.io.

Installation

The installation of this add-on is pretty straightforward and not different in comparison to installing any other Hass.io add-on.

2. Install this add-on.
3. Click the Save button to store your configuration.
4. Start the add-on.
5. Check the logs of the add-on to see if everything went well.
6. Carefully configure the add-on to your preferences, see the official documentation for for that.
