10.3. MQTT (for smartDEN IP-16R-MQ only)

The

smartDEN IP-16R-MQ

supports MQTT protocol V3.1.1. The module runs a

MQTT client that publishes the relays states, and subscribes to messages to switch
the relays On/Off.

Figure 10.2.

smartDEN IP-16R-MQ

working as MQTT client

Two types of publish/subscribe topics modes are supported: plain (non-encrypted)

and encrypted.

10.3.1. Plain (non-encrypted) mode

In this mode,

smartDEN IP-16R-MQ

uses non-encrypted topics to get relays

states and switch relays On/Off.

Encrypt

option in

MQTT Settings

page must be turned off in order to work

in this mode.

Below are described all the available topics in order to communicate with

smartDEN IP-16R-MQ via MQTT protocol. All topics begin with the following prefix:

SmartDEN_MQTT16R/<

MAC identifier

Where, <

MAC identifier

> is the MAC address of the board written without the

colons. For example:

SmartDEN_MQTT16R/E8EADA123456/Get/#

SmartDEN_MQTT16R/E8EADA123456/Set/All
