to weewx-user

I have installed WEEWX on a RPi 3B+ with a AB Electronics I2C to 1wire master.

I have loaded all the required modules, etc.

I used simulator when I originally installed WeeWX to make sure I could see the results in the index.html file.

All good, so far.

I see my sensors with the "PYTHONPATH=/home/weewx/bin python /home/weewx/bin/user/owfs.py --sensors --i2c-1" line command as well as the read...

I have edited the weewx.conf file to get the sensors, interface, driver, etc.

and yet I can't get it to work. Here is the tail =f /var/log/syslog:

Is this a follow on from your july 2019 posting? I'm assuming you
still haven't got it running?

The syslog messages ; w1_master_driver w1_bus_master1 etc
These will be from the Pi's kernel driver for 1-wire devices that are
connected directly to the GPIO pins
I don't believe your setup needs this running at all, I have no idea
if it interferes or not but raspi-config will turn that feature off or
on. See the following...
https://www.raspberrypi.org/forums/viewtopic.php?t=196691
https://www.abelectronics.co.uk/forums/thread/23/w1-master-driver-w1-bus-master1-family-0-for-00-700000000000-f8-is-not-registered

You have a working owfs.py install. It seems a reasonable mapping is
being returned from the script so the sensors are present and talking
via owfs.py.

After using the simulator, did you change the driver to owfs?
[Station]
station_type = OWFS

What's the [OWFS} section showing from weewx.conf, in particular the sensor_map.

http://www.weewx.com/docs/utilities.htm#wee_debug_utility )
wee_debug will parse your weewx.conf file into a suitable format for
posting here (no introduced typos to confuse). The usual advice is to
check that the output has been cleaned of sensitive info (passwords
etc) before posting.

A full log would be good, this may have nothing to do with your owfs.py install.
Turn debug on in weewx.conf (debug = 1) , restart weewx and run it for
a couple of archive intervals then post the resulting log (or
extract) to this group and we may be able to see what is happening.

Have you tried running it directly from the command line using
something like (paths may differ)...
python /home/weewx/bin/weewxd /home/weewx/weewx.conf
If it is running you should be getting OWFS LOOP packets displayed on
the screen within 30 seconds or so (If memory serves, 20 seconds is
the default).

Ah Ha...

In the above output, ie within weewx.conf, you have your sensor mapping
listed under sensor_type, and no sensor_type entries.

If you change the sensor_type heading to [[sensor_map]], that should fix
the bulk of it.

Additionally, unless you know otherwise (ie you've changed the hardware
connections) windSpeed can drop the counters.ALL as your new sensor_map
will allocate it as counter.A (its default within owfs.py)

windSpeed = /uncached/1D.D01101000000

As for what should go under the now empty [[sensor_type]] section, try
the following...

[[sensor_type]]
windDir = aag_windvane
windSpeed = aag_windspeed
rain = rainwise_bucket

That's based on my memory, which recalls that you are running an
original AAG weather station?

I'm not sure what the AAG rain gauge would default to, I didn't find a
mention of anything specific in owfs.py but a rainwise_bucket returns
0.1" per tip, which owfs.py converts to 0.0254 cm. Once it's working
you can tweak its output.

With the exception of the pressure related values (there is/was a 1-wire
pressure sensor) these will need to become prefer_software. The 1-wire
sensors will only return the sensor value, the driver adjusts some
values but it's safe to assume that no calculations are performed.
Then again, you probably require a humidity sensor to calculate most of
those so it's possibly mute.

Don't forget. If you run weewx directly from the command line you should
see LOOP values spat out at every 30 seconds or so. This can quickly
tell you what is and isn't responding.

python /home/weewx/bin/weewxd /home/weewx/weewx.conf

You may need to tweak that command for your setup

Glenn,

Thank you so much! Your imput has been invaluable! I am now seeing data on the index.html file being populated. Now I need to calibrate the wind direction, and get my rain gauge all calibrated which is indeed the original Dallas Semiconductor rain gauge (before AAG, but I believe the same type.

Bless you for all your help!

Sincerely,

Bret

Excellent

Your sensor_map entry for rain will also drop the counters.ALL suffix.
The script uses counter.B as the default.

rain = /uncached/1D.81B500000000/

If needed, you can pin it down by using the following commands to run
owfs.py directly.
One of them will be right...

sudo PYTHONPATH=bin python bin/user/owfs.py --reading
/1D.81B500000000/Counter.A

sudo PYTHONPATH=bin python bin/user/owfs.py --reading
/1D.81B500000000/Counter.B
