Hi @tekka , I've gone through the steps in your guide using MQTTGateway as gw sketch.
When I start my new node (burned with mysbootloader) I only see the repeating message "FIND_PARENT" in MySensor Debug window and "RX 0;0;3;0;9;read: 0-0-255 s=255,c=3,t=7,pt=0,l=0,sg=0:" in the MYSController Debug window.
The message appears every time the led is blinking on the node (approx every 2 seconds).
Any idea why it doesn't request node id? Have also tried with AutoID without success.
Thx!
