Hi,

I now have this script running. 
Indeed this shouldn't be necessary but I've had both issues (Weewx crash 
and USB issue) so I think these scripts are nice to have in case something 
goes wrong until these issue are ironed out. Of course we should provide TF 
with logs from these events.

I still have commented out the settings that initiate a reboot, so I will 
have to do that manually in that case, for now.
So it's good to have those scripts sending email at errors.

Yes it would be great to have these functions in the same script, with 
toggle's, so I would appreciate it. Lets see if there are someone else that 
would like it. 

Well, thank you so far for all help! Learning all the time now :)

BR Mikael
