Hi all
I have devised a method to export my Air Quality Data (AQI) from my Arduino
based weather station to Weewx (it can't be sent via the usb port with the
rest of the data). It involves sending the data via a UDP broadcast packet
from the station, this is then captured by a small Python script on my
Weewx Pi and written to a txt file.
The txt file data looks like this
AQI25=5.50,AQI100=4.10,AQIIndex=22,AQICO2=967
>From the Weewx wiki I have crafted the beginning of a service to import the
data to my Wewwx database (extended with the 4 new data fields) but I'm not
sure how to complete that task. So far I have this, which I think will grab
the first value - how do I parse the other 3? Is it as simple as just
adding more lines such as event.record['AQI100'] = float(value) etc?
*import* syslog
*import* weewx
*from* weewx.wxengine *import* StdService
*class* WDAQIService(StdService):
*def** __init__*(self, engine, config_dict):
super(WDAQIService, self).__init__(engine, config_dict)
d = config_dict.get(*'WDAQIService'*, {})
self.filename = d.get(*'filename'*, *'/home/pi/AQIData.txt'*)
syslog.syslog(syslog.LOG_INFO, *"WDAQIImport: using %s"* %
self.filename)
self.bind(weewx.NEW_ARCHIVE_RECORD, self.read_file)
*def** read_file*(self, event):
*try*:
*with* open(self.filename) *as* f:
value = f.read()
syslog.syslog(syslog.LOG_DEBUG, *"WDAQIImport: found value of
%s"* % value)
event.record[*'AQI25'*] = float(value)
*except* Exception *as* e:
syslog.syslog(syslog.LOG_ERR, *"WDAQIImport: cannot read value:
%s"* % e)
Thanks
Colin
