Thanks, Karen. I understand what you are saying but, not being a programmer, I don’t know how to make that sort of modification. The sensor sends out VWC data as a percentage amount which shouldn’t need to be converted to any other unit as I want to display it directly as read. The data I’m displaying is in the correct form (% VWC) but the unit being displayed with the value remains as “cb.” For example it now reads “26 cb at 10:15” and I want it to read “26 % VWC” or even simply just “26%.” SoilMoist1 needs to display % and not cb. It seems to be a label problem. Cheers, Bob On Thursday, November 7, 2024 at 9:57:02 AM UTC-5 Karen K wrote:
