Locking and managing the Ampio module password

What is it for?

This feature allows you to protect an Ampio device by setting a password. The password enables:

• locking the module against unauthorised access,
• unlocking a previously locked module,
• changing the existing password,
• setting a password for the first time if it hasn’t been configured yet.

What exactly does the password lock?

Once the password is set and the module is locked:

• all access to module configuration is blocked,

• all memory blocks such as:

  • logic,

  • parameters,

  • access control,

  • and other functions - become read-only or inaccessible for changes.

    • No changes can be saved to the module (neither locally nor via MQTT),
    • Only data that was accessible prior to locking remains visible via MQTT,
    • After restarting MQTT (e.g., due to an update), the module will not reload full configuration if it remains locked.

Where to find it?

In modules that support this feature, you will find the password lock option next to the gear icon in the main device list.
