====MQTT Versions====

The [[distribute:start|Distribution]] addon supports two different ways of sending data to MQTT servers.

The //point-based// method sends a single MQTT message for each individual point of information. Every temperature, pressure, mode and status has it's own distinct MQTT message.

For example, topic **/data/ardi/Main Site/Ambient Temperature** will be given a message containing...

<code>
22.4
</code>

The //object-based// method sends a single MQTT message for each **ARDI asset**, combining the different pieces of information about an asset in a single MQTT update.

This results in far fewer messages and a simpler namespace, at the cost of more information sent per-message.

In this example, topic **/data/ardi/Main Site** will be sent a message containing...

<code javascript>
{
    "Ambient Temperature": 22.4,
    "Mode": 1,
    "Speed": 92.5
}
</code>
