[weewx-user] Re: Potential barometer issue (Meteostick)

I would make sure it is completely in the shade at all times. I see the meteostick manual even says to ignore indoor temperature and humidity as humidity will always be 30% and temperature will be reading high due to temperature rise from the electronics!! Goodness knows what warmth from the

[weewx-user] Re: Potential barometer issue (Meteostick)

Good idea! It actually could be sunlight. The time (late afternoon) would fit. And yes, August 3 was a day without much sun. So was Aug 7, where the effect was also less pronounced. Today will be a sunny day, so I'll move the Meteostick a bit into the shadow and see what happens. Am Freitag,

[weewx-user] Re: Potential barometer issue (Meteostick)

Where is the Barometer located? Indoor? Since temperature and humidity influence measurement of pressure, it is possible that the measurement is just wrong just because you are opening a window for ventilating the house or when the barometer sensor is hit by direct sunlight during the day and

[weewx-user] Re: Potential barometer issue (Meteostick)

That's really weird. Your barometer line is absolutely parallel to the other two lines. But when looking at the weewx code, the effect of the temperature calibration on 'barometer' should definitely by bigger. Ahh .. maybe that's the reason: Belchertown is only at a height of 180 meters! I'm

[weewx-user] Re: Potential barometer issue (Meteostick)

We may need Tom, mwall or Gary to offer their insight on the weewx internal code question. I'm using the Meteostick driver as well however my hardware is a Moteino (Arduino) with Meteostick emulated code on it. So my hardware is not an exact

[weewx-user] Re: Potential barometer issue (Meteostick)

My initial question was to try and isolate the readings (to see where the problem is)... Does the Meteostick have a way to see its values without weewx? (web ui? serial port?) Trying to see if the stick is the problem or if it's weewx. The driver looks like it expects "pressure" from the

[weewx-user] Re: Potential barometer issue (Meteostick)

Yes, the pressure values come from the Meteostick. I'm less concerned about the actual level of the barometer values - that's something I can calibrate. I'm more concerned about the ups and downs that heavily correlate with my temperature and humidity values. Am Donnerstag, 8. August 2019

[weewx-user] Re: Potential barometer issue (Meteostick)

Actually this is probably a bad comparison since I think the Meteostick comes with it's own barometer on the stick itself - so the values won't be identical. On Thursday, August 8, 2019 at 3:25:37 PM UTC-4, Brezentrager wrote: > > The values on the console are generally lower. Currently -

[weewx-user] Re: Potential barometer issue (Meteostick)

The values on the console are generally lower. Currently - Console: 1015.1 // WeeWX: 1017.9 The difference gets bigger in the morning and smaller in the afternoon/evening. Am Donnerstag, 8. August 2019 21:19:42 UTC+2 schrieb Pat: > > Just curious how these values compare against your station's

Just curious how these values compare against your station's console? On Thursday, August 8, 2019 at 2:46:23 PM UTC-4, Brezentrager wrote: > > Hi, > AWEKAS doesn't accept my barometer figures since they differ too much from > comparable stations in the region. > > When looking at the issue in
