Weewx stops working: WH2320 using weewx-wh23xx driver and Sofaskin

[Nicky G]

Hello, my Weewx installation has failed a couple of times in the last few days. I only have logs from the last crash after turning on debugging. I hope this is the correct place to post and that you may be able to help resolve these problems? This group has been very useful in getting Weewx working, it has been running for just over a couple of weeks in total.

As per the subject line I am using a WH2320 station with the driver from here: https://github.com/matthewwall/weewx-wh23xx 

Using Sofaskin.

Raspberry Pi.

From my logs - let me know if more information is needed:

nicky,

thanks for posting.  please try driver version 0.7 (commit c0727c2)

this will let weewx continue to run when index errors show up.  most likely these are due to corrupt memory in the weather station.

if you see a bunch of 'decode failed' messages in the log, please post them so we can see if there is a pattern to the bogus bytes.

Thank you very much! I will give it a try and let you know how I go on and will check through the logs for decode failed messages.

Thanks,
Nicky

Hello, just to update you I have not had any further crashes, I have checked the logs and cannot see any decode failed messages.

Thanks,

Nicky
