Hi All,
Thanks to Michael to pointing out it was expecting Degrees Fahrenheit in
this context.
Based on the following comment and my config...
[StdConvert]
# DO NOT MODIFY THIS VALUE UNLESS YOU KNOW WHAT YOU ARE DOING!
target_unit = METRIC # Default is 'US'
Apparently, I don't know what I'm doing so I've just changed my code as
follows...
roofTempC = float("50") (This will be the Degrees Celsius from the RPi
measuring the Roof)
roofTempF = (roofTempC * 1.8) + 32
event.record['extraTemp1'] = roofTempF
Thanks,
Glenn.
