First I realized, that rainRate > 0 but rain == 0. And it was raining. So I
looked into it.
weewx.conf says:
[Station]
...
station_type = WeatherLinkLiveUDP
[WeatherLinkLiveUDP]
wll_ip = XXX.XXX.XXX.XXX
poll_interval = 10
driver = user.weatherlinkliveudp
hardware = Davis Vantage Pro2
Before midnight, no error is logged into syslog. All is normal. Starting
with 00:00:05 today WeeWX complains to syslog about a negative rain value:
May 26 00:00:05 LokalWiki weewx[365882] WARNING weewx.qc: 2021-05-26
00:00:06 CEST (1621980006) LOOP value 'rain' -0.14960629921259844 outside
limits (0.0, 10.0)
This message is repeated for *every loop packet*. The value increases
during the day a little bit.
May 26 21:05:50 LokalWiki weewx[365882] WARNING weewx.qc: 2021-05-26
21:05:50 CEST (1622055950) LOOP value 'rain' -0.015748031496062992 outside
limits (0.0, 10.0)
When I realized all that, I stopped WeeWX and started it again. No more
messages from that moment on. And rain is registered again as normal.
Reading weewx.sdb results in:
sqlite> select dateTime,rain,rainRate from archive where
dateTime>=1621980000 order by 1;
1621980000|0.0|0.0
1621980300|0.149606299212598|0.0
1621980600|0.0|0.0
...
1621980300 == 26.05.2021 00:05:00 CEST, which is the time, when the
messages started. For all other timestamps up to the restart rain is 0.0
Can someone draw sense out of that?
