Hi again Tom,
Definitely not enough with my new StdQC configuration. I still get wrong
observations into my DB.
Just now I have this in my weewx.conf:
[StdQC]
[[MinMax]]
rain = 0, 10, mm
rainRate = 0, 3, mm_per_hour
And I still get messages like these:
ene 13 16:10:17 meteopi weewxd[193488]: WARNING weewx.qc: 2025-01-13
16:10:00 CET (1736781000) Archive value 'rainRate' 4.046533333333339
outside limits (0.0, 0.11811023609999999)
ene 13 17:00:17 meteopi weewxd[193488]: WARNING weewx.qc: 2025-01-13
17:00:00 CET (1736784000) Archive value 'rain' 0.539 outside limits (0.0,
0.3937007874015748)
ene 13 17:00:17 meteopi weewxd[193488]: WARNING weewx.qc: Discarding
observation
ene 13 17:00:17 meteopi weewxd[193488]: WARNING weewx.qc: 2025-01-13
17:00:00 CET (1736784000) Archive value 'rainRate' 4.399999999999997
outside limits (0.0, 0.11811023609999999)
ene 13 17:00:17 meteopi weewxd[193488]: WARNING weewx.qc: Discarding
observation
Which generate these values into my DB:
dateTime rain
rainRate
1736781000 0.09899999999999998 3.079999999999999
1736784000 NULL 4.3119999999999985
It seems that the rainRate filter is not correct or not filtering.
Any clue?
Thanks once again for your help.
