Home assistant add-on: changedetection.io

Thanks to everyone having starred my repo! To star it click on the image below, then it will be on top right. Thanks!

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

Main app

Webui can be found at <your-ip>:5000.

PGID: user
GPID: user
TZ: Etc/UTC specify a timezone to use, see https://en.wikipedia.org/wiki/List_of_tz_database_time_zones#List
BASE_URL: Specify the full URL (including protocol) when running behind a reverse proxy

Connect to browserless chrome (from @RhysMcW)

In HA use the File Editor addon (or Filebrowser) and edit the Changedetection.io config.yaml : /homeassistant/addons_config/changedetection.io/config.yaml

Add the following line to the end of the file: PLAYWRIGHT_DRIVER_URL: ws://db21ed7f-browserless-chrome.local.hass.io:3000/chromium?launch={"defaultViewport":{"height":720,"width":1280},"headless":false,"stealth":true}&blockAds=true

Remember to add a blank line at the end of the file too according to yaml requirements.

The "db21ed7f-browserless-chrome.local.hass.io" hostname was got from the CLI in HA, using arp, but you should also be able to use your HA IP address. Then restart the Changedetection.io addon - 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.

Add my Hass.io add-ons repository to your Hass.io instance.
Install this add-on.
Click the Save button to store your configuration.
Start the add-on.
Check the logs of the add-on to see if everything went well.
Carefully configure the add-on to your preferences, see the official documentation for for that.
