Missing data on Tycon TP1080WC

[Victor]

   Hello everyone, i recently found out about this project and wanted to test it out to see how it would work for me, currently I'm running pywws running on a Tp-link router with OpenWrt. But to be honest I really wanted to update the way I get the data from the router, from printing out a .CSV file to a more readable/user friendly web page. 
   The device I'm using to run weewx is a Raspberry Pi 3 B+ and the weather station is a Tycon TP1080WC, the problems that I'm having is reading out the stations values, using live output I can see the program can read out values properly. It can get the wind direction properly and the reading from the pressure sensor but it doesn't add their value either to the web page data , realtime.txt file or the CSV( comma separated value) file (for the pressure sensor it adds the maximum read out as the current value). Trying to debug the problem myself i went through and install weewx using both the debian install guide and the setup.py method bout to the same effect. Using the minimal  knowledge I have in python I tried to edit both the crt, csv weewx extentions to try and print out the values the programs are reading to try and get a basic understanding of the problem i'm getting, but sadly to no success. I've attached all the files I think will be needed to get a basic understanding in the configuration and problem.

P.S. Don't worry about the time and date not being the same on all of the readouts , that my fault not the programs.

To see what weewx is receiving from the station stop weewx and run it directly and not as a daemon.  The LOOP and REC packets should then be output onto the rpi console as they are received.  Set your station to a 5 minute archive interval (300 seconds) using wee_device and set the archive interval in weewx.conf to also be 300 seconds.  You should then get approximately 5 LOOP records per REC archive record.  You will need to make sure that barometer and altimeter are specified as being 'software generated' because the 1080 only outputs pressure.  See the wiki for the difference between the 3.

This should help you to see what is going on.  Sort out the inputs and the database before going on to the outputs and webpages!!  If you have not changed the archive interval to 300 seconds the default on the 1080 is usually set for 30 minutes - so nothing would happen for 30 minutes in weewx.

Thank you for the assistance Andrew, after calibration the pressure sensor it works like a charm ( I had skimmed over that table in the wiki and missed the proper settings for the sensors) , but still I wasn't able to figure out where the problem with the missing wind direction data comes from. 

[Andrew Milner]

do the LOOP packets contain the wind direction when you are running weewx manually (not as a daemon)??

when you look at the database (use sqlite3) what do you get for wind direction?

select dateTime, windDir from archive where 1; 

should give you some indication

[Victor]

My bad forgot to mention that in the last post. The LOOP packets return that the value of the  wind direction is 'None' (I've attached a file with a sample of the returned packet). Looking through the database entries everywhere where the windDir value is mentuned its value is 'NULL' ( Also attached )

[Andrew Milner]

Right - looking at the first files you attached the wind speed was 0.  If windspeed is zero wind direction will also be set to None (unless you set the option and I forget what it is in weewx.conf.

The live readout also has a windspeed of zero.  You cannot have a meaningful direction if you do not have a windspeed so the None is a correct value in this instance.

[Andrew Milner]

the option is in wxcalculate section of weewx.conf:

[StdWXCalculate]

The calculation service calculates derived quantities such as dewpoint, windchill, and heatindex.

Some hardware provides derived quantities, others provide only raw observations. The calculation service provides derived quantities for hardware that does not provide them, and known algorithms for hardware that provides unreliable or antiquated calculations.

The section [StdWXCalculate] consists of a group of Observation defaults, followed by a subsection [[Calculations]] that specifies the calculation strategy to be used for each derived quantity.

ignore_zero_wind

Indicates whether the wind direction should be undefined when the wind speed is zero. The default value is True: the wind direction will be undefined when wind speed is zero.

To report the wind vane direction even when there is no wind speed, change this to False:

[StdWXCalculate]
    ...
    ignore_zero_wind = False

[Victor]

Thank you so much Andrew. I was left with the impression that even without any wind the program will still print out the value of the current position of the weather vane. After re-soldering the anemometers cable back and re-attaching it back to the weather vane I can confirm that was the root of my problem. Thank you as well for quoting the setting I can change to force it to print out a value.
