Install on Synology

[Chris]

Hello,

Can I have some help in installing wfrog on my Synology DS216Play ?

I installed all dependencies manually but 1 : lxml.

This is the error : unable to execute '/usr/local/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-ccache-gcc': No such file or directory

Is it another dependency ? Can I have some help ? I have limited knowledge on this.

I downloaded the package on https://pypi.python.org/pypi maybe it is not the good one.

Thank you

I cannot help you about that other than telling you that there is people who have installed wfrog (and its dependencies) in Raspberry which is also an arm architecture machine. Therefore in principle the package should be available. Maybe trying an older version...

Look if by chance you have the lxml module as a OS module instead of a pypi module ...

Then maybe you can also try on lxml main page: http://lxml.de. There are instructions on how to build lxml from the sources.

Jordi.

Ok, I succeeded in launching wfrog.

I don't know exactly what did the trick as I tried many things...

Next step, I need to get the data from my weather station and customize the templates.

Thank you.

Another feedback.

Ok, wfrog works BUT it doesn't pull data from my weather station.

Debug says that USB connection has failed.

I know it can work because I already installed wfrog with that same weather station on my previous Synology NAS (which was D212J)

Any help appreciated.

Weather Station : Oregon WMR88

NAS Synology : D216PLAY

Drivers tried : auto / wmrs200 (which is the one recommended) / wmr200

[Jordi Puigsegur Figueras]

One thing to check: wfrog needs permission to open the USB port. Either you run wfrog as root or give permisions (udev rules). 

It might not be this. It is just a guess without much information.

To run as root I just need to sudo the command, right ?

Here is the debug log if it can help :

sudo ./bin/wfrog -d

Hi,

Hi, It looks like the pyUsb package does not install libusb now. 

Maybe you need to install libusb by itself. E.g.:https://pypi.python.org/pypi/libusb1

Jordi.

[Chris]

It was already installed. Your comment had me thinking that maybe it was a conflict between all the libraries I installed.

I uninstalled libusb/pyusb via PIP, which warned my NAS that notified me that I needed to repair Python, which I did.

And then voila ! No more USB errors !

I still have no data showing (sometimes current temp is ok though), I will now try to figure it out.

Thank you

Ok, I got it working now !

Still one problem : google charts won't show, I get a "Failed to load resource: the server responded with a status of 400" error on the web developer console, if I open the image link manually though it would work, and then if I refresh the wfrog webpage it will show up (until data changes or cache is emptied). Any idea?

I resolved my problem.

if it can help anyone else here :

 I replaced "chart.get_url()" on wrenderer/render/chart.py file with (chart.get_url()).replace("http://www.google.com","https://chart.googleapis.com") and now every chart is loading !
