WeeWX not starting after a power outage

[Muireadach O Connor]

My power went for a few hours this morning unexpectedly.

I do have backups of the conf file, templates and database via a cron script which runs at midnight every night but would rather not go through a restore unless it's really needed as I've never had to and no doubt it's probably not going to be very straightforward (for me)

I'm running this on Raspbian on a Pi 2, any ideas/suggestions?

dmesg looks fine to my eyes:

Try deleting all the .pyc files. These are compiled versions of the .py file. Something like

find /usr/share/weewx -name "*.pyc" | sudo xargs rm

should do it

Tom, cannot thank you enough, that's sorted it.

Would you believe I have a Pi UPS sitting in a drawer for the last forever?, just never got round to installing it, lesson learned.

Thanks again.
