PiMonitor

[Captain]

Earlier today, I added PIMonitor - latest version from git hub to my v4.11786 install of (Docker)Domoticz on a raspberry pi 3B+. Of the 17 devices created only, CPU temp amd CPU count have any data - the remainder are all blank or zero. Here are the log messages that are repeated every minute or so. Do you have any suggestions on how to troubleshoot this issue? Thanks
