Hello, i cannot get it to work. It was working in my previous setup. But now I cannot find what is wrong with new install and RPi.

I have value from PM sensor stored in .txt file, and I try to write it into databas field "pm10_0"

- I added file pm10.py into /weewx/bin/user/pm10.py it contains following code:

import syslog

import weewx

from weewx.wxengine import StdService

class pmbservice(StdService):

def __init__(self, engine, config_dict):

super(pmbservice, self).__init__(engine, config_dict)

d = config_dict.get('pmbservice', {})

self.filename = d.get('filename', '/usb/www/pm10.txt')

syslog.syslog(syslog.LOG_INFO, "pmb: 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, "pmb: found value of %s" % value)

event.record['pm10_0'] = float(value)

except Exception, e:

syslog.syslog(syslog.LOG_ERR, "pmb: cannot read value: %s" % e)

Then I added into weewx.conf the following line:

[Engine]

# This section specifies which services should be run and in what order.

[[Services]]

prep_services = weewx.engine.StdTimeSynch

data_services = user.pm10.pmbservice

process_services = weewx.engine.StdConvert, weewx.engine.StdCalibrate, weewx.engine.StdQC, weew>

xtype_services = weewx.wxxtypes.StdWXXTypes, weewx.wxxtypes.StdPressureCooker, weewx.wxxtypes.S>

archive_services = weewx.engine.StdArchive

restful_services = weewx.restx.StdStationRegistry, weewx.restx.StdWunderground, weewx.restx.Std>

report_services = weewx.engine.StdPrint, weewx.engine.StdReport

And when i restart weewx i get the following error.

python3 syntax: no comma between ‘Exception' and ‘e'.

also you would want to be using weewx logging rather than syslog

Rather than roll your own, why not just use the extension filepile?

Thanks to both of you. I used Tom's "filepile" because i have several other sensors as well and now only one extension is needed, and it is working great.
