I am still in "testing mode".
I had some problems with the node, it stoped receiving messages but did always work with the button.
Yesterday i built a new node and uploaded the sketch and it seems to work better.
Here is the sketch i use, I changed the pin for the button due to missing digital pins on my pcb.
And I am back on using digital pins for the stepper driver for the same reason.
I greyed out buttonpin 2. I don't think it is needed.
I also greyed out the heartbeat-part as I had problems. Just for testing. Don't know if it is suitable when using Home Assistant.
