I don’t recommend reverting to 4.2 as it has some issues. The problem you are describing now is do to some issues in your db; specifically, intervals of 0 (4.3 is less forgiving). I found a thread to address it from Jan 6. I’ve pasted Tom’s response below. Rather than deleting records, if you know what the correct interval should be, you could update the records.
Good heavens. That's a lot. I wonder where they all came from? No matter. Here's how to fix (and sorry for giving you the wrong path to the database). # First stop weewx sudo systemctl stop weewx cd /var/lib/weewx # Make a backup: sudo cp weewx.sdb weewx.sdb.backup # Delete all records where interval equals zero: sudo sqlite3 weewx.sdb sqlite> delete from archive where interval==0; sqlite> .quit # Restart weewx sudo systemctl start weewx If you get this error again, there is something wrong with the configuration of your system. -tk > On Jan 20, 2021, at 1:56 PM, Invisible Man <axelle.apvri...@gmail.com> wrote: > > Ok, I see WMR200 has been removed in December 2020, and is now an extension. > I install the extension, and I get more errors > > -- Logs begin at Wed 2021-01-20 16:50:14 CET. -- > Jan 20 22:53:44 vegan python2[7867]: weewx[7867] CRITICAL __main__: **** > File "/usr/share/weewx/weewx/manager.py", line 1255, in patch_sums > Jan 20 22:53:44 vegan python2[7867]: weewx[7867] CRITICAL __main__: **** > self.recalculate_weights(start_d=datetime.date(2020,6,1)) > Jan 20 22:53:44 vegan python2[7867]: weewx[7867] CRITICAL __main__: **** > File "/usr/share/weewx/weewx/manager.py", line 1182, in recalculate_weights > Jan 20 22:53:44 vegan python2[7867]: weewx[7867] CRITICAL __main__: **** > self._do_tranche(mark_d, end_of_tranche_d, weight_fn, progress_fn) > Jan 20 22:53:44 vegan python2[7867]: weewx[7867] CRITICAL __main__: **** > File "/usr/share/weewx/weewx/manager.py", line 1215, in _do_tranche > Jan 20 22:53:44 vegan python2[7867]: weewx[7867] CRITICAL __main__: **** > weight = weight_fn(self, rec) > Jan 20 22:53:44 vegan python2[7867]: weewx[7867] CRITICAL __main__: **** > File "/usr/share/weewx/weewx/manager.py", line 1366, in _calc_weight > Jan 20 22:53:44 vegan python2[7867]: weewx[7867] CRITICAL __main__: **** > "Non-positive value for record field 'interval': %s" % > (record['interval'],)) > Jan 20 22:53:44 vegan python2[7867]: weewx[7867] CRITICAL __main__: **** > IntervalError: Non-positive value for record field 'interval': 0 > Jan 20 22:53:44 vegan python2[7867]: weewx[7867] CRITICAL __main__: **** > Exiting. > > I'm really unhappy about that :( > When you upgrade, you expect things to work, not things to get broken.
