I'm running Weewx 3.8.2 on a Raspberry Pi with Rasbian Jessie. Weather station is a Davis Vantage Pro2 wired.
I'm getting the wind direction reported at only the major compass points: (0,22.5,45,67.5,90,112.5,135,157.5,180,202.5,225,247.5,270,292.5,315,337.5). This behavior started on Oct 14 but I can see periods in the archive where this also occurred in the past. For example, on May 5, 2018 it did this for a 6 hour period. What I expect, and what normally happens, is to report the full range from 0 to 360. A dump of the May 2018 period is below. The Vantage Pro displays wind direction down to the degree even when weewx is recording the quantized direction. This means the weather vane on the roof can measure and the data is getting down to the console. Why is weewx reporting less accuracy than is being measured? | 2018-05-05 00:00:00 | 26.8534531239994 | | 2018-05-05 00:15:00 | 40.1762746405119 | | 2018-05-05 00:30:00 | 31.8391669072265 | | 2018-05-05 00:45:00 | 27.6576423981335 | | 2018-05-05 01:00:00 | 45 | | 2018-05-05 01:15:00 | 0 | | 2018-05-05 01:30:00 | 0 | | 2018-05-05 01:45:00 | 0 | | 2018-05-05 02:00:00 | 0 | | 2018-05-05 02:15:00 | 337.5 | | 2018-05-05 02:30:00 | 315 | | 2018-05-05 02:45:00 | 315 | | 2018-05-05 03:00:00 | 315 | | 2018-05-05 03:15:00 | 315 | | 2018-05-05 03:30:00 | 315 | | 2018-05-05 03:45:00 | 0 | | 2018-05-05 04:00:00 | 315 | | 2018-05-05 04:15:00 | 315 | | 2018-05-05 04:30:00 | 315 | | 2018-05-05 04:45:00 | 0 | | 2018-05-05 05:00:00 | 0 | | 2018-05-05 05:15:00 | 0 | | 2018-05-05 05:30:00 | 0 | | 2018-05-05 05:45:00 | 22.5 | | 2018-05-05 06:00:00 | 45 | | 2018-05-05 06:15:00 | 45 | | 2018-05-05 06:30:00 | 67.5 | | 2018-05-05 06:45:00 | 67.5 | | 2018-05-05 07:00:00 | 67.5 | | 2018-05-05 07:15:00 | 54.2728729207129 | | 2018-05-05 07:30:00 | 59.2775430647446 | | 2018-05-05 07:45:00 | 62.1555767325972 | -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
