It publishes everything it has by default.
In weewx.conf as always
If you look at the mqtt.py code, it seems like you can limit the
observations it sends by explicitly setting them as desired:
class MQTT(weewx.restx.StdRESTbase):
def __init__(self, engine, config_dict):
"""This service recognizes standard restful options plus the
following:
Required parameters:
server_url: URL of the broker, e.g., something of the form
mqtt://username:password@localhost:1883/
Default is None
Optional parameters:
unit_system: one of US, METRIC, or METRICWX
Default is None; units will be those of data in the database
topic: the MQTT topic under which to post
Default is 'weather'
append_units_label: should units label be appended to name
Default is True
obs_to_upload: Which observations to upload. Possible values are
none or all. When none is specified, only items in the inputs list
will be uploaded. When all is specified, all observations will be
uploaded, subject to overrides in the inputs list.
Default is all
FWIW, I just let it publish everything and only subscribe to topics I care
about (specifically, I just grab weather/loop and grab the pieces therein).
I also set append_units_label to False so that 'if' I subscribe to a
specific topic, I'll just get the data value.
