Frequently asked questions
How do I trigger a Home Assistant automation from a web page change?
Paste the URL you want to watch and point the alert at a Home Assistant webhook. When the AI detects a meaningful change, it calls that webhook, which you can wire to a sensor update or automation. So a product coming into stock or a new release can flip a light or send a notification.
Will it trigger on every tiny change?
No, and that is the point. The AI reads the page and decides whether the change actually matters before firing the webhook. Ads, cookie banners, navigation, and view counters are ignored, so your automations only run on real events like a status flip or a fresh release, not on background churn.
How fast does the trigger fire?
Use instant alerts and the webhook fires within minutes of a meaningful change, which keeps your Home Assistant automations responsive. If you would rather batch things, a daily or weekly digest is available too. This works on any public page, so you can wire up almost anything. It is free to start.
