Thank you for the response Shannon. I stripped and tinned the wires on the sensor, connected it to the 6-pin screw terminal as directed, connected the screw terminal with a grove cable to a SD-12 port on a Mayfly 1.1 board with the jumper moved to the 12v position. I also changed the sensor address to “2”. For some reason, I am getting an error reading of -9999, which I think means that my sensor isn’t getting power. I used the code in the menu a la carte example on github. I think the D22 pin is set to high in that example. Does anyone know what I could be doing wrong?
