Thanks for your reply. No, I have no instance of weewx running. The

I have forgotten which tools I have to use and the time is becomming

You shouldn't lose data if it's in the weewx database from before you
started unplugging and moving hardware around.

That looks to me like weewx is unable to talk to the weather station
hardware. Did you power everything down before plugging it back in ?
Did you ensure that whatever you plugged in was connected well before
powering up the pi ?
It's pretty hard to work these things remotely, but in general
whenever you start unplugging/plugging hardware in that's a good place
to start debugging....
Thanks for your reply. Yes I did that several times but it will not
start up. Both methods have the same effect. Mysterious for me is the
syslog entry \
10:45:40 kangoo systemd[1]: Started LSB: weewx weather system.
Vince,
Thanks for your reply. Well, the fact that the device is found on USB
bus-001 says that the device is connected and the fact that it knows
which driver to load indicates, in my opinion, that it knows which
driver to use. However. the fact that it says "unable to load driver"
can mean that the driver is not found but how can it read address
0x0000fc? But maybe mysteriously has between the unplugging and
connecting of the device the driver mysteriously disappeared?
However, it is still in /home/weewx/bin/drivers/te923.py so I don't
think that is the reason.
In short I am stumped.
Joep
