hi joe,
use the inputs stanza. for example, this will upload all observations,
with overrides to outTemp and windSpeed:
[StdRestful]
[[MQTT]]
...
unit_system = METRIC # default to
metric
[[[inputs]]]
[[[[outTemp]]]]
name = inside_temperature # use a label other than
outTemp
format = %.2f # two decimal places of
precision
units = degree_F # convert outTemp to F, others
in C
[[[[windSpeed]]]]
units = knot # convert the wind speed to
knots
by default, every observation will be uploaded. use obs_to_upload to
default to uploading NO observations, then add in the ones you want. for
example, this will upload *only* outTemp and inTemp using the default units
and formatting:
[StdReport]
[[MQTT]]
obs_to_upload = none
[[[inputs]]]
[[[[outTemp]]]]
[[[[inTemp]]]]
fwiw, this is a pattern found in may uploaders, including emoncms and
influx.
