Well looking into the rainrate/rainRate issue has been most interesting. First up rainrate has been used in skin.conf for the rain rate plot as follows since the SteelSeries Weather Gauges first directly supported WeeWX:
[[images]] x_label_format = %H:%M show_daynight = true [[[daybarometer]]] [[[[barometer]]]] [[[dayrain]]] yscale = None, None, 0.02 plot_type = bar [[[[rain]]]] aggregate_type = sum aggregate_interval = 3600 label = Rain (hourly total) [[[dayrainrate]]] [[[[rainrate]]]] But why has this never caused a problem or been noticed before? I think the way in which plot data is obtained and the introduction of xtypes holds the answer. Before WeeWX v4 plot data was obtained via a call to manager.getSqlVectors() which itself is encapsulated in a try...finally statement. The result being that any error (for example a non-existant obs type) was effectively swallowed and no data returned by manager.getSqlVectors(). The image generator would then plot this non-data which resulted in a plot devoid of data. Given that rain rate plots are seldom looked at, quite often show no data, and also as this plot was only used as a mouseover on the SteelSeries rain rate gauge, it is not surprising it's lack of data was never noticed. Now consider the new xtypes regime, plot data now comes from xtypes and if my xtypes understanding is correct, the xtypes are searched until one is found that can return the required data. In this case no xtype can return data for field rainrate which results in a weewx.UnknownType error which is highlighted in the log and painfully obvious to the user. Of course the fix is simple, replace rainrate with the correct field rainRate. This then got me wondering about the $hour.rain.sum.raw issue. I am still convinced this is tied to an underlying lack of rain data for at least one full hour in the day. My testing yesterday showed the gauge-data.txt template would handle such a lack of rain data without problem, which is counter to Phil's experience. But I was running under WeeWX 3.9.2 which does not use xtypes, I am now thinking there is a subtle difference in the data returned by xtypes in some corner cases. So far my understanding of xtypes has been fairly limited to just what I have needed to bget by in working on WeeWX 4.0 (which has not been much). Clearly I have a bit more reading to do (@tkeffer - warning there will be some xtypes questions inbound) and I will spend some time today seeing if I can replicate the issue.
