WeeWX service for additional types from a file to a WeeWX data stream
-
Arrange to have your new data saved to a file, say
/var/tmp/pond.txt. It should be in the following format:extraTemp1 = 45.5 extraHumid1 = None myVoltage = 12.2The value
Noneis a valid value and signifies a bad data point. -
Download and install the extension
weectl extension install https://github.com/tkeffer/filepile/archive/master.zip
-
Edit the new stanza
[FilePile]to reflect your situation. Here's an example:[FilePile] filename = /var/tmp/pond.txt unit_system = US ignore_value_error = False [[label_map]] myVoltage = supplyVoltage
In this example, the incoming data will be found in the file
/var/tmp/pond.txtand it will be in the US Customary unit system. See below for optionignore_value_error.The incoming observation type
myVoltagewill get mapped to the WeeWX typesupplyVoltage. The other two types in the file (extraTemp1andextraHumid1in the example above), do not appear in the mapping, so they will appear under their own namesextraTemp1andextraHumid1. -
Restart WeeWX. For example:
sudo systemctl stop weewx sudo systemctl start weewx
-
On every archive interval, your temporary file will be read, parsed, and its contents added to the WeeWX record.

Include a stanza in your
weewx.confconfiguration file that looks like this. Adjust the options as necessary:[FilePile] filename = /var/tmp/pond.txt unit_system = US # Or, 'METRIC' or 'METRICWX' ignore_value_error = False # Map from incoming names, to WeeWX names. [[label_map]] myVoltage = supplyVoltage # Incoming name 'myVoltage' will get mapped to 'supplyVoltage'

Add the FilePile service to the list of
data_services:[Engine] [[Services]] ... data_services = user.filepile.FilePile ...
-
Put the file
filepile.pyin your WeeWXusersubdirectory. For example, if you installed usingsetup.py:cp filepile.py /home/weewx/bin/user

Restart WeeWX. For example:
sudo systemctl stop weewx sudo systemctl start weewx

ignore_value_error controls what happens if a value is unable to be converted
to a floating point value. Examples:
outTemp = foo
windSpeed = N/A
If set to False (the default), an exception of type ValueError will be raised, which is likely to cause program
termination. If set to True, the value will be ignored.
