Alltime low values missing date

[metalmi...@gmail.com]

Hi guys, 

I added the stats for alltime and seven days, but unfortunately for the alltime low values, there's no date displayed. For example: Lowest outside Temperature -10,9 °C N/A. So there is no date and time displayed, only N/A. It is only for low values, the other ones are shown correctly. It is also only for alltime, for seven day everything is as expected. 

I changed this (week--> alltime) in stats.py.

# First, create TimespanBinder object for all time. This one is easy

        # because the object timespan already holds all valid times to be

        # used in the report.

        all_stats = TimespanBinder(timespan,

                                   db_lookup,

                                   context='alltime',

                                   formatter=self.generator.formatter,

                                   converter=self.generator.converter,

                                   skin_dict=self.generator.skin_dict)       # 4

Afterwards I added alltime = %x %X to weewx.conf, restarted weewx, but that didn't help.

Can someone help me with this?

Thank you very much!

Florian

1. What version of WeeWX?

2. Let's see what's in your database. If you used a package installer, your database is likely located at /var/lib/weewx/weewx.sdb. If you did a setup.py install, it's at /home/weewx/archive/weewx.sdb. Assuming the former,

sqlite3 /var/lib/weewx/weewx.sdb

sqlite> select dateTime, datetime(mintime, 'unixepoch','localtime'), min from archive_day_outTemp order by min asc limit 5;

sqlite> select dateTime, datetime(dateTime, 'unixepoch','localtime'), outTemp from archive order by outTemp asc limit 5;

sqlite> select dateTime, datetime(dateTime, 'unixepoch','localtime'), outTemp from archive where outTemp is not null order by outTemp asc limit 5;

sqlite> .quit

This will print out the five days with the lowest temperatures and their times using 3 different methods. Post the results.

fyi: I had to install sqlite3.
To give you a little more background: First, the weather station was connected to a Raspberry Pi 3, now I moved to a vm on my unraid host. On the Raspberry Pi, which has now nothing to do, I switched from Fineoffset USB to Simulator to make it sort of test instance for weewx. On this Pi, the behaviour reported above occurs. If everything works, I will transfer it to the vm.

As suspected. You are getting bitten by issue #635. This can happen when there is no data in an archive interval. 

The fix is to upgrade to V4.4.
