MQTT Plug-in for Commandfusion iViewer Simple MQTT Client for Commandfusion iViewer

Usage is quite simple:

• Add MQTT.js file to Project Script Manager
• Create TCP System with link and port of your MQTT Broker. (Standard MQTT port is 1883)
• Create first two commands - MQTT_Connect and MQTT_Subscribe. Those should only have appropriate javascript code(example in script)
• Create a macro - MQTT_Start, which should call two commands above with 100ms Interval(first connect, then subscribe). Assign this macro to Startup macro in System Properties.
• Create single feedback with (.*) regex.

Use Add Command to generate publish messages. Just put MQTT_Publish function in Javascript field,according to example in script. For example:

For switch: Field Javascript: MQTT_Publish("/myhome/command/Light_FF_Bath_Ceiling/state","ON", system)

For slider: Field Command Value: {{[sliderval]}} Field Javascript: MQTT_Publish("/myhome/command/Temperature_Setpoint/state",data, system) Do not forget to set "Javascript sends command value" flag

To process feedbacks:

• Create a UDP Socket Loopback system with IP 127.0.0.1
• As End Of Message Character define \x0D in System Properties of this system
• For each feedback create new feedback and in regex provide appropriate regex assuming that your incoming data in this case will have a look like topic=value.For example: /myhome/in/Light_FF_Bath_Ceiling=(OFF) /myhouse/office/Room_Temp=(.*)

• packet length is calculated a bit primitive way, and not according to standard (this should be fixed with recent commit by Jarrod)
• Security/Authorization to be added
