Fitted the stand-alone reader *on an 'empty' Raspberry without weewx* (just
Raspian_Buster + latest Domoticz_beta).
In new folder /home/pi/Install-files
Slight name-change to match my system-configuration.
First result from Putty's CLI shown below.
pixx@raspberrypixx:~ $ sudo python
/home/pi/Install_files/hp3001_reader_python_script.py
Traceback (most recent call last):
File "/home/pi/Install_files/hp3001_reader_python_script.py", line 4, in
<module>
import usb.core
ImportError: No module named usb.core
More or less as expected the 'import'-section causes first trouble, calling
modules not present.
Not further tested, expecting 'more of the same'. Seems to demonstrate that
'stand-alone' in this case is not 100%.
After installation on that machine of *weewx in the 'basic' form according
to the UserGuide*, the result is as below (for my configuration):
pixx@raspberrypixx:~ $ sudo python
/home/pi/Install_files/hp3001_reader_python_script.py
{'dateTime': 1581756586, 'extraHumid4': 88, 'extraHumid5': 88,
'extraHumid2': 54, 'extraHumid3': 88, 'extraHumid1': 56, 'extraTemp4':
11.4, 'extraTemp5': 11.4, 'extraTemp2': 16.8, 'extraTemp3': 11.3,
'usUnits': 17, 'extraTemp1': 17.2}
Looks good!
Probably simplest solution with least effort is installation of weewx
before running of the reader-script:
installation may be, either 'basic', or via setup.py
*Next questions*
- the output of this script on Putty's CLI is recognized as a JSON-file
- reading a program from another programmer is not always easy.
Therefore the quick&easy requests to the programmer (*Olivier?*) for
support of my views:
1. What is the line of the script with the print-command and the
JSON-file-name for this output?
2. Output by the JSON-file now dynamically limited to data from valid
sensors.
=> if a sensor goes down (such as 'battery empty'), then a different
JSON-file.
For subsequent processing somewhat easier/simpler if 'empty' fields are
still there.
How/where to change the script to get that?
