4.2.3 Commands
It is possible to send commands by the MQTT/MQTTS server to the WebdynSunPM concentrator.
To do this, the “command” and “Result” topics must be entered in the concentrator conguration (See
chapter 3.2.2.5.4: “MQTT”).
When a command is published on the “Command” topic on the MQTT/MQTTS server, it is retrieved by the
concentrator. The command is executed by the concentrator and the result of the command is published
on the “Result” topic.
