Why does this inject not work ?
Check your configuration. The instructions don’t tell you but you need to include Node Red port of 1880.
So it should be http://192.168.0.xxxx:1880/smartthings/webhook
That’s how I got it working about 10 months ago and I notified developer but it looks like instructions haven’t changed. I assume the port is still necessary.
Yes everything is working on smartapp side, there is no problem. I just dont know how to manipulate ST items from node-red … There is nosimple examples anywhere
