Hello from JS. Topic: /v1/devices/1004/datas
{
“humidity”:12,
“temperature”:7
}
The data published by SCADA and the subscribed data vary significantly. How to specify the attribute names?

Send /1004/command = {“Val”:0}
@val Why is the value 0? I wrote the value in the “send command”, but it didn’t work. An error “invalid command” occurred.

MQTT Publisher Driver writes each channel to it’s own topic. It cannot write 2 channel in the same topic, e.g., { “humidity”:12, “temperature”:7 }

Please clarify if you use MQTT Client or MQTT Publisher Driver?

Why is the value 0? I wrote the value in the “send command”

Please provide screenshot of the settings, and a command that was sent.
