MQTT integration

MQTT lets a screen talk to an MQTT message broker — a lightweight publish/subscribe system common in IoT and building-automation setups. With it, a screen can react to messages from other systems (or report its own events) on a shared topic.

What you configure

• Enable the integration on the device.

• Broker URL — the address of your MQTT broker.

• Username / password — credentials for the broker (kept on the device, not in docs).

• Topic — the MQTT topic the screen subscribes/publishes to.

Typical uses

• A building system publishes a message → screens switch to a specific message/playlist.

• Trigger emergency or alert content from a central control system.

• Tie signage into an existing IoT/automation stack you already run.

Setup notes

This is an advanced, network-dependent integration — set it up with impressBox so the broker, topic, and credentials match your environment. Test that messages actually reach the screen before relying on it operationally.
