Thanks,
I have the rate set on one of my stationless displays, however the calculation does seem accurate - and it is different to the rate displayed on the weather station. I know calculating rain rate is tricky - giving the resolution of the tipping bucket, and choosing over what what time frame the sample is taken over - one second, 1o seconds, etc. That’s why I think it would be great if the rain rate graph could be made to plot what the station is displaying, rather than recalculating it.
I’m a bit of a thunderstorm nut, and being able to record and plot on a graph that for 15 seconds the rain rate was 210 mm/hour kind of gets me going 
Hah Hah
I know the steepness of the rain amount plot graphically illustrates the rate - and I suppose you could manually expand the X axis of the graph and work it out, but I like the idea of seeing the numbers too.
Similarly, it’d be great if the numeric rain rate showed what was on the station.
Minor issues - great application overall.
