1. Install an MQTT broker, for example on the Raspi

sudo apt-get install -y mosquitto mosquitto-clients

2. Send MQTT messages from trivum to the broker

  • go into the trivum web configuration by typing <trivumip>/beta into your web browser,
    which also enables Beta features.

Line Input

  • enable MQTT under: Automation / MQTT

Line Input
Line Input

Enter the IP of your broker (Raspi). Keep the topic prefix. (trivum)

  • create a Macro under: Configuration / Macros with a step: send MQTT message

Line Input

  • create a zone action under: Configuration / zones / first zone / define actions
    With action: run a macro, then select the above macro.

Line Input

  • open a web visualization:
    In your web browser, open a new tab. Type the IP of trivum. Now you have a web visualization.

Line Input

On first use it will control the first zone. At the right, the macro action appears.

  • click or touch on the macro action. It will send the MQTT message.

Test receive directly on the Raspi like:

mosquitto_sub -h localhost -v -t "light/#"

which will show:

light/living/1/status/set 1

3. Control trivum by MQTT messages

In the trivum web configuration, a device topic prefix can be configured, which is trivum by default.

The trivum device then listens on these topics:

trivum/zone/1/status      - get status of first zone
trivum/zone/1/status/set  - set status of first zone

The zone status is an integer with these possible values:

0     - zone off
1     - zone on (audible)
2     - zone is muted (on but not audible)

So, if zone 1 is switched on or off, trivum sends trivum/zone/1/status with value 1 or 0.

To switch zone 1 on or off, send trivum/zone/1/status/set with value 1 or 0.
