@bobbylx Thanks for your help. I did not use your config.js recommendation because it just looks like you are converting celsius to fahrenheit. I did use the custom.css lines and it worked great. Thanks again.
@sdetweil Thanks for the info.
I have no idea why this worked, but after clearing the journals, the thing started working as expected. I changed the fetch frequency back to once every 10 minutes, and it seems happy for now.
Will do some more testing and will let you know
