Hi there,
I installed paho-mqtt et all as per this guide: https://github.com/weewx/weewx/wiki/mqtt
Now when I start the service I get this:

May 04 13:53:28 raspberrypi python3[984]: weewx[984] CRITICAL __main__: Caught unrecoverable exception:

What could I have missed here?

Thanks

Perhaps you installed the python2 version instead of the python3 version.

Hi there,

I followed the instructions from weewx. Installed all 2.7 python. 
Weird isn't it?

Any further idea to debug?

All your posted errors say python3

Interesting, there might be a mess up there at this point!

Thanks for pointing that out.

If you are wanting python2 then run everything by using it explicitly.
There are examples in the setup.py guide

All right, removed all of python3 and with python2 all runs fine now, thanks for the help!
