To publish tag's value in TeslaCloud you have to use name of the topic of Tag's pointer in the topic and value in the payload. If you use SparkplugB metric's name contains full name (group/subgroup/subsubgroup/name) of the tag. Value will be represented in SparkplugB format in this case.

Example (not SparkplugB):

Topic: spBv1.0/Group/NCMD/EdgeNode/SetTemperature

Value: 25.3
