Hi Rob,
Regarding the rain faill per hour, I am not sure if what you proposed is
correct. What you are doing in your code, if I understood you correctly, is
the following:
if packet[2:4].encode('hex')!='fffe':
Rh = None
else:
Rh = (256*ord(packet[2])+ord(packet[3]))*2.54/100
So in your else branch, you will always have packet[2]=ff and packet[3]=fe. Of
course, you are now getting output regarding the rain but the Rh will
always be 1664.56, isn't?
As it is not saved in DB, I don't use the Rh and have never checked its
values. I don't have neither an UV sensor, so I can't help in your second
question.
