Register webhook

Use this action to manually register the Netatmo webhook with the Netatmo backend. The webhook lets Netatmo push instant events to Home Assistant. Home Assistant normally registers it for you, so you only need this action to recover from a connection issue.

Using this action from the user interface

If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.

To register the webhook from an automation or a script:

1. Go to Settings > Automations & scenes.
2. Open an existing automation or script, or select Create automation > Create new automation.
3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
4. In the Then do section, select Add action.
5. From the search box, search for and select Netatmo: Register webhook.
6. Select Save.

This action does not support targets. In the UI, you are not prompted to choose an area, device, entity, or label.

Options in the UI

This action has no additional options in the UI.

Using this action in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this action as netatmo.register_webhook. A basic example looks like this:

action: netatmo.register_webhook

This registers the webhook with the Netatmo backend.

Good to know

• Home Assistant registers the webhook automatically. Use this action only to recover after a connection problem, such as when events stop arriving.
• The webhook needs your Home Assistant instance to be reachable from the internet. For more details, see the Netatmo integration documentation.
