Hi,
The Twitter extension only offers basic unit conversion in the string it
publishes, it’s really a case of all or nothing. By default the tweet uses
the unit system of your WeeWX database for all obs. I’m guessing you are
using the METRIC unit system in your database (target_unit = METRIC under
[StdConvert] in weew.conf), the METRIC unit system records rain in cm
<http://weewx.com/docs/customizing.htm#units> which explains what you are
seeing. If you read through the config instructions at the start of
twitter.py you will see that you can use the unit_system config option to
set the unit system to use in your tweets, for example:
[StdRESTful]
[[Twitter]]
....
unit_system = METRICWX
Will use the METRIC_WX unit system which will give you rain in mm but wind
speed will be in m/s (refer my earlier link). As an aside using unit_system
= US would give rain in inches.
Unfortunately, as the Twitter extension stands you cannot change units for
individual obs.
