When I type the IP address port and “sn0”, e.g., 192.168.1.12:8086/sn0, I get one line displayed. It has 32 zeros, “00000000000000000000000000000000”.
I am using Ray’s OpenSprinkler Pi and I do have three expansion modules for 32 zones. I’m currently using 27 of them. Do these 32 zeros indicate something to you?
