Hi All

Bit of advice please for a noob.

Running Weewx on an RPi 4, Raspian 10 (Buster) and recently upgraded to v4 from v3.

I was aware that Wunderfixer stopped working some time ago in v3 (unless you were a Linux guru, which I'm not) due to api issues.

Now that I have upgraded to v4, all is working fine and using Wunderfixer now works direct from the command line as it should having inserted my api into the config file. 

However, I now wish to go back to running Wunderfixer as a Crontask twice a day as recommended in the Wunderfixer instructionsat 1158hrs and 2358hrs.

I have inserted the Crontask (via crontab -e) instructions as per those shown in the Wunderfixer instructions but with log options enabled:

16 13 * * * /home/weewx/bin/wunderfixer -v

From the log I get the following message:

/bin/sh: 1: /home/weewx/bin/wunderfixer: not found

Not sure that I'm pointing the crontask to the correct location, weewx for me is installed in /etc/weewx, not /home/weewx, and my weewx directory does not have a /bin sub directory, in fact I've no idea where wunderfixer is actually running from!

Can anyone point me in the right direction as to where I should direct the crontask to or have an example to hand that I can use.

Thank you

Dave

Run the command : which wunderfixer

That should give you the correct path.   Mine is at /usr/bin/wunderfixer
