Hi mwall,
Thanks for the pointers, I have some Qs.
This is what my JSON looks like at http://192.168.1.9/FullDataString:
{"FullDataString":
"25.60,89.30,29.42,101926.00,592.16,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,1,2019-10-17
18:39:19,NIBM,0,-1,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,V:1,WXLMB
,0,,,0,,,0", "id": "1", "name": "OurWeather", "hardware": "esp8266",
"connected": true}
This station supports Air Quality and Lightning detection sensors which
I've currently mapped (to ignore) as extraTemp and soilTemp for now.
The trouble from the JSON is multi-part:
1. After part14 which is dateTime, the user-configured Station Name is
sent for which I don't see an option to specify in
https://github.com/weewx/weewx/blob/master/bin/schemas/wview.py
2. Same issue for these bits towards the end of the JSON: V:1,WXLMB
,0,,,0,,,0", "id": "1", "name": "OurWeather", "hardware": "esp8266",
"connected": true which I'm happy to ignore as of now.
Here's the output of me trying to troubleshoot it:
$ PYTHONPATH=/home/weewx/bin python2 /home/weewx/bin/user/ourweather.py
Traceback (most recent call last):
File "/home/weewx/bin/user/ourweather.py", line 65, in <module>

,0,,,0,,,0", "id": "1", "name": "OurWeather", "hardware": "esp8266",
"connected": true}
NameError: global name 'true' is not defined
How do I ignore sections of the JSON?
This is what my current ourweather.py looks like, any pointers are
appreciated -

P.S. I don't know Python, just some Bash.
Thanks,
AD
