HD16 - Confusion with Mixer!
I recently acquired a RainMachine HD16 and I am confused about the mixer!
I read some of the documentation and saw the following image with the explanation "Notice the red line -- this is the RainMachine Mixer, this is an aggregation of the enabled Weather Services"
How is this an aggregation... the 3 weather services, on October 28th, are showing a temp of about 58 degrees, whereas the Mixer is showing a temp of about 32 degrees!!
I only have one weather service so far, but shouldn't the mixer have the exact same values? Here is an image of the Rain (QPF) chart... the forecast for July 12th on METNO is for 9.1mm of rain at 6:00am, but mixer is showing 41.2mm at the beginning of the day!! The difference is even more if I look at the same time point!
Can someone please explain why I am seeing these types of variances?

First you will need to mouse over the graph and check the days that mixer line and weather service lines are showing. Mixed data for a day is always set at 00:00, weather services have their reported hours but for mixer we aggregate entire day and save the result at 00:00.
Temp is an average between all temps, Max Temp is an average of max temps reported by weather services, similar for min. For precipitation is a SUM for all hourly precipitation reported by ONE weather service and then averaged across multiple weather services. This value, as I wrote above, is saved at hour 00:00 each time we compute it so the dot will appear before the other dots from weather services.
Temp is not used by algorithm, we just plot it, min/max temp and the rest are used.
