Shutdown HP1000

[ried...@gmail.com]

Hello

Unfortunately, weewx keeps crashing after a Linux update.

I once attached the log from the syslog. Maybe someone can help.

As hardware I have an HP1000 weather station with Hp driver and a virtual server (Linux Ubuntu) on a disk station DS 218+.

The whole thing lasted a few months. Until I did abt-get updat and upgrade.

Greetings André

I wrote that driver - so thank you for putting 'HP1000'  in the title; I really can't read through all messages looking for the occasional one like this.

What version of the OS are you running - you mentioned performing a recent update: from what and to what?

Also have you moved from Python 2 to Python 3 as that was a trigger for this in the past?

Finally what version of the HP1000 driver are you using - the latest version on Python 3 should not be doing this now?

Just for kicks, what version of WeeWx are you using? I've tested it running V4.1 but I'm not aware of any breaking changes in later versions of WeeWx.
