Hi,

Looks like you need to install the python module configobj. How you do that will depend on whether you are running WeeWX under python2 or python3.

I suspect you will be running under python 3 so use:

$ sudo apt install python3-configobj

if not under python2 use:

$ sudo apt install python-configobj

Once configobj is installed re-run the WeeWX installation.

[Neville Davis]

Thanks will look at it straight away

Nev

[Neville Davis]

Well that was it for that problem weewx installed but now I have a lot of red on status report.

My station is a home brew using i2C and other sensors this is reporting a hardware naming error ??

Any ideas ?

Yes, the problem is that your driver has not implemented the hardware_name property. You will find it mentioned in the Implement the driver section of the Customization Guide. I cannot explain why the same driver worked under 3.9.1 (if it in fact did), as far as I am aware implementing the hardware_name property has always been mandatory.

Gary

[Neville Davis]

Ok I will look into it I have had the system running for a few years the last software update was to 3.9.1 when it came out...Its been some time since I visited my software about time i did it again.

Thanks for the info.

It doesn't need to be anything flash, just needs to implemented and return a string. You will find heaps of examples in the drivers in the weewx/drivers directory.

This is my driver file, had no problems before.. but always a first time :)

Like I said I can't explain why this error would not come up with the same driver under 3.9.1,I just checked the 3.9.1 documentation/code and hardware_name was mandatory. In any case easy fixed, you just need something like this in your driver class:

    @property
    def hardware_name(self):
        return "MyDriverName"

Fileparse driver is a good simple example.

Well done those edits that problem with my driver cleared others have happened. I then tried to run on simulator and I get

 So now I have a bit of work to do.

I have another system I have started to build up so will proceed with that get the basic system working then find out why I am having issues with my driver.

Don' suppose there is a quick revert to version 3.9.1 ?? in the interim

You did a setup.py install so just install 3.9.1 over the top. The user directory won't be touched and of course backup your data. Might be worthwhile looking at the log rather than the abbreviated systemctl view, the last part of the systemctl output tells me nothing, there almost certainly will be more in the log.

A tip for posting logs too, rather than using systemctl status weewx run another terminal and tail the WeeWX log file (nominally /var/log/syslog) in that terminal with something like tail -f -n50 /var/log/syslog and take copies as required or edit and copy from the log file. that way you can get a longer log extract not the 'looking through a straw' view that systemctl gives you.

Thanks very much Gary,,,,

I have almost everything working in version 4, all my i2C modules are detected wind sensors air-conditioning data etc all except my 1wire rain system.

Everything is setup for python 3 so I understand from other posts of the issue with python-ow.

I installed ow-server and pyownet and I get this from the command prompt

pi@raspberrypi:/home/sensorreadings $ python getrain.py //localhost:4304/1D.E3AB0D000000/counter.B

       16570

pi@raspberrypi:/home/sensorreadings $ 

which is great and does show correct bucket tip info.

What I am now attempting to do (with very little success , i am blaming my age(75) :) is how to get the command line arguments required with the owget.py script and call that script from my main sensordata.py script (this collects all data from i2C network and wind.

What I want to end up with e.g 16570 returned to my main script and I process it further from there.

I have been looking at subprocess but I am way over my head and any guidance would be appreciated.

Neville

[Neville Davis]

I have managed to hack owget.py to output directly to a csv file I create in a ramdisk...and I get this by not entering any arguments..so a simple call to to owget.py.

Using this csv I will pull the data into my main sensor reading file.. 

The csv holds the correct data but I get some extra characters I will have to mask...so getting there :)

Neville

[Neville Davis]

Actually I will run my getrain.py as a service so all I will need to do is access the ramdisk.
