Exactly.

That's the big advantage of assigning a type to a unit group. All the
formatting and conversion machinery becomes available.

Thanks!
I assume that this works 'out of the box' because I have defined the unit 
for sunshine time as 'minute' (rather than something like 'sun_minute') and 
weewx already 'knows' how to convert between common units of time. For my 
solar production example, you would presumably need to use the unit names 
as they are defined in one of the energy groups..

Re: [weewx-user] Scaling Units for different reports

[Tom Keffer]

Sure. Just tell the report to use hours instead of minutes.

For example, for tags, it becomes $week.sunshine.sum.hour

For a plot, use option 'unit' in skin.conf.

[ImageGenerator]
  ...
  [[week_images]]
...
[[[week_sunshine]]]
  unit = hour
  sunshine

[weewx-user] Scaling Units for different reports

['Peter Fletcher' via weewx-user]

As noted in a different thread, I am working on a small extension to 
calculate and store sunshine time (time when the sun is out, rather than 
covered by clouds). I am saving the number of *minutes* of sunshine during 
the archive period in each archive record. Sunshine minutes are fine for 
display on daily reports and graphs, but I would rather display the more 
usual sunshine hours on weekly, monthly, and longer reports. Is there an 
easy way to tell the report generator to scale the units it uses for 
different report periods? I can see this being useful for other categories 
of data, too. You might, for example want to display solar production in Wh 
for the daily reports but in kWh for monthly and longer ones.

I feel that XTypes may provide the answer to this, but couldn't really get 
my head around how it would work, in practice.
