Problem since Weewx 4.6

[Remy Lavabre]

With the previous version 4.51, no problem since 1 year.

Since 4.6.0 the records are good on the database, but I have errors in the log file and the value in the "current conditions" of the skin Seasons don't move.

They remain frozen at the last known value with Weewx 4.5.1. In fact, the Season skin no longer works but the data is correctly saved in the database.

Attached is the log file. I can't get my skin season to start again! :-((

HELP !

I saw this when I upgraded my system yesterday.

The problem was my ancient custom extension broke due to group_deltatime API change in 4.6.0 - the fix is documented in https://weewx.com/docs/upgrading.htm#API_changes - all I did was add context='long_delta' to my python extension and restarted weewx and all was good again.

[Remy Lavabre]

Thank you for your answer Vincent.

Could you indicate me which python file exactly to add the New value 
context='long_delta ? And where I must add this New value in the py file ?

I have seen the article you indicate me but i did not understand what to do...

Than you . Cordialy vincent

I've found my problem.... Thank you Vince !

The problems were in 2 extension file : lastrain.py and lastfrost.py (date of the last rain and frost and duration without rain and frost).

Before :

        # Wrap our ts in a ValueHelper

        last_rain_vt = (last_rain_ts, 'unix_epoch', 'group_time')
        last_rain_vh = ValueHelper(last_rain_vt, formatter=self.generator.formatter, converter=self.generator.converter)

        # next idea stolen with thanks from weewx station.py
        # note this is delta time from 'now' not the last weewx db time
        #  - weewx used time.time() but weewx-wd suggests timespan.stop()
        delta_time = time.time() - last_rain_ts if last_rain_ts else None

        # Wrap our ts in a ValueHelper
        delta_time_vt = (delta_time, 'second', 'group_deltatime')
        delta_time_vh = ValueHelper(delta_time_vt, formatter=self.generator.formatter, converter=self.generator.converter)

AFTER :

       # Wrap our ts in a ValueHelper
        last_rain_vt = (last_rain_ts, 'unix_epoch', 'group_time')
        last_rain_vh = ValueHelper(last_rain_vt, formatter=self.generator.formatter, converter=self.generator.converter)

        # next idea stolen with thanks from weewx station.py
        # note this is delta time from 'now' not the last weewx db time
        #  - weewx used time.time() but weewx-wd suggests timespan.stop()
        delta_time = time.time() - last_rain_ts if last_rain_ts else None

        # Wrap our ts in a ValueHelper
        delta_time_vt = (delta_time, 'second', 'group_deltatime')
        delta_time_vh = ValueHelper(delta_time_vt, context='long_delta', formatter=self.generator.formatter, converter=self.generator.converter)

And now... ALL IS OK !!  THANK-YOU VERY MUCH VINCE !!!!! ::-))

Yes - I updated my lastrain extension on github yesterday...

[didier....@gmail.com]

I have updates weewx to 4.6 and lastrain-extension (compatible weewx 4.6)

But I have exactly the same error of Remy after reboot

I've checked lastrain.py and I have the correct §:

        try:
            # 4.6.0 breaking change - must specify either context='short_delta' or context='long_delta'

            delta_time_vh = ValueHelper(delta_time_vt, context='long_delta', formatter=self.generator.formatter, converter=self.generator.converter)

        except:
            # this works for prior to 4.6.0

           delta_time_vh = ValueHelper(delta_time_vt, formatter=self.generator.formatter, converter=self.generator.converter)

Do you have an idea?

[didier....@gmail.com]

I have found my error:

To avoid posting my own weewx.conf (with account and password), I have removed this file in the git process

Also version in weewx remained in 4.3.0.....

I change in 4.6.1rc and it's OK now

Sorry for my previous message
