Change Detection
Tell me when that page changes
Watches any web page and notifies you when the part you care about changes — a price, a stock line, a council notice, an exam timetable. Point it at a page, select the region visually, choose how often, and it does the checking that would otherwise be you refreshing a tab.

changedetectionInstalling it
Open the dashboard, find it in the App Store and press Install. Or from a terminal on the box:
sudo homebox install changedetectionWhere to open it
| Service | Port | First login |
|---|---|---|
| Change Detection | :5000 | No account by default. Set a password under Settings if this box is not only yours. |
Open it at your box's address with that port — the dashboard links to it directly once it is running.
Good to know
- The browser sidecar is what makes it work on modern sites — anything rendered by JavaScript is invisible to a plain fetch
- Select the exact element with the visual picker rather than watching the whole page, or you get an alert every time an ad rotates
- It can notify through Gotify, so a price drop can reach your phone without email
