TReX User Manual v15.30 Firmware
Configuration
To configure MQTT operation on the TReX, refer to the MQTT Sub-Menu section.
Connecting to an MQTT Broker
When the TReX starts the IP configuration will be displayed. Once the TReX has connected to
the MQTT broker service the icon
should be displayed on the screen.
If the authentication fails while connecting the MQTT broker, then the icon will blink on
the screen.
The MQTT broker service will provide tools showing connected devices and will allow testing
from another MQTT device such as phone application. If the connection to the TReX fails,
first prove that you are able to connect successfully to the MQTT broker from another device.
Subscribed Topic
The TReX subscribes only to a single MQTT topic. This is TREX/MI. Whenever a MQTT
message is received by the TReX there is a short duration screen popup showing part of the
value published to TREX/MI.
To transmit a message the value of used for TREX/MI should be in WT Protocol format.
To control outputs, both analog and digital the value should be in the WT Output Control
format. To send commands and configuration to remote devices, use the WT Output Control
format.
Full descriptions of both these formats can be found in the WT Protocol section.
Examples:
