I wrote before that I had to be missing something. Pin1 marking on the board - classic. Thanks a lot! Would be draining my head, before/if I’d found out much later.
Looks like working now
Yes, it does. Thanks again:
Great. You do not need to run it as root…just put a user in the same group (in my case “i2c” as the device).
I know, don’t worry. It will be accessible through cgi and snmp, so I’ll make sure it won’t run with elevated access rights.
