Example configuration

This short use case will guide you through a topic filter configuration.

Before you begin

You've already reserved the firmware_version_update namespace.

You want only selected devices subscribing to the topic.

You want only your admins to be able to publish updates.

Your topic path is:
company/model/firmware/version

How to

  1. Click Add ACL.
  2. Add a device identity topic filter, replacing the model with the %c wildcard.
    company/%c/firmware/version
  3. Add the * wildcard as a subscriber group.
    Note: Do not use the * wildcard in the regular topic filters. It will open your topics to any users.
  4. Click Add ACL.
  5. Add a wilcarded topic filter, replacing the model with the + wildcard. I want to have my admins to be able to publish a new version of the firmware, regardless of the device.
    company/+/firmware/version
  6. Add admin1 user group as the Publishers.
  7. Click Save.
