mqtt connection problem
Latest activity Reply by Christopher Stapels

I isolated a var that I'm interested in, and I want to connect Node-RED to thingspeak to show the values on the graph. The problem is the node "mqttout": I connected it to the server mqtt3.thingspeak.com and the port 1883, and with the device with right username and password. It shows "connected", but the graph is still the same, I can not upload the varabiles.

Have you created an MQTT device in ThingSpeak and given permissions for MQTT to write to the channel? See the instructions in the MQTT Basics.
Yes I have it, I don't know why it doesn't work
I reccomend troubleshooting using the desktop client. You can see instructions in the help link I send above.
Also , a common casue of not seing data on the field plots is sending non numeric data by accident. Make sure to export the recent data in your channel to be sure its not there but in an unexpected format.
