I finally successfully managed set up few nodes with the Prometheus exporter except one.
Differently from the other nodes which are fine, this note simply expect a 0/1 which represent the status of a pin low/high.

I tried both, gauge and metric but I still have errors.
Any suggestion nohow to solve this issue?
Thank you
