weewx stopped with

[peter]

weewx stopped this morning with an error I don't understand. I also doesn't want to start either.

Can some please advise what would be the cause?

I have Davis Vantage Vue + few other inputs from text files I log into database. This week I added logging of a big integer values into 'hail' field.

This is the status:

I've deleted the weewx.sdb and weewx.db files and restarted. Same error... I am completely lost...

Hi,

Looks like when you added your new data you have a nan (not a number) being put into the database. 

Check your changes to see to see if the large number is too large.

Need to see your changes to understand more.

I've used the original database again and did a

wee_database weewx.conf --drop-daily

I got a full log which ends with the same error. I've also set the new columns to NULL value so there should be no NAN.

Found a solution. Long story short: temperature value read from a text file was 'inf'. Consequently, other recalculations failed and resulted in nan.

Solution: fix the temperature sensor :-)

Most likely, the NaN will be in the input data stream, not the database. Did you look there?

It happened again with exactly the same error. I've deleted (manually...) all 'Inf' values in one column but am unable to start weewx. It always exits with this message. I've looked for 'nan' values but there were no such entries.

I'd appreciate suggestions... Station type: Vantage Vue.

This was again my fault (same as in the original report). I haven't looked at all the files that feed the database. I found the 'nan' there and removed it. I've also improved the process that writes to these external files so no 'nan' should be written anymore.

Thanks for your help.
