Hi,
This is a stupid simple question, but I don't know how to change dynamically the topic of an MQTT Out node.
I've read that I need to leave it blank and it will take the topic from the input msg, but it doesn't work.
Motor switch node
Color picker node
I'm using mqtt-explorer to debug and track messages. I see the topic and message if I fill the topic property, but nothing is happening if I leave blank.
What Am I doing wrong?
you have msg.motor
and msg.colour
(note the msg.
part)
Did you mean to actually use a fixed topic of motor
and colour
? If yes, then change the msg.
dropdown to a/z
(string)
what you currently have is telling the node to get the value of msg.motor
and msg.colour
from the msg
object at runtime (which i assume is not actually present)
Thanks I figured it out a few minutes after posting this message.
I'm from the embedded and native world and this NodeRed and all the web techs are new to me. I have so much to learn and makes my head hurt.
