So when the WeatherDuino communicates with cumulus it tells it each tip is 0.254mm and cumulus then applies a 1.27 multiplier, because that's what I have set. If that's the case then the multiplier should be 1.00 not 1.27. Do I have that right?

Here is the misunderstood. WeatherDuino doesn't pass to Cumulus, the user defined value of each tip bucket. It only passes the number of tips occurred. Then, Cumulus computes the rain based on the assumption that each tip have a value of 0.2mm, that's the reason you need to set a multiplier.

I already have explaining this, so many times, that it starts to be annoying to me, mainly because it seems that my instructions don't have any credit.

I'm gonna say this for the last time: For any rain gauge, where each rain tip is different from 0.2mm, we should always set a multiplier on Cumulus according to this formula:


Multiplier = Bucket Type / 0.2

0.254 / 0.2 = 1.27

Each one will do whatever he likes, but the correct way is the one explained above.

Just received the first rainfall with my new 8" rain gauge. Cumulus MX recorded 0.25" of rain and the Pro2+ receiver is showing 0.20".

Regarding to this, I will recheck if there isn't any problem with the rain values shown in inches, on the Weatherduino display. Can you please also check if the rain units in Cumulus MX are set to inches.
