Meteohub Update 4.0 "multi station" (highly experimental)

[piombo]

WMR200, rc6

As it got colder I recognized that wind chill is not displayed in graphs either.
There is still the problem with no sea level pressure in graphs (correct sea pressure displayed in dashboard).
Both values are calculated by meteohub, but there is no difference with data taken from the WMR200.

Thanks!

I now have a very simple "proof of concept" 1-wire plug-in running. The application polls 1-wire temp, humidity and pressure sensors every 30 seconds, builds the results into a thb9 raw record, then prints that to stdout.

I know the plugin has been started by Meteohub and continues to run because as well as providing the sensor data to stdout, the same data (plus an incrementing prefix) is being dumped to a simple text file (plugin.log) in the myweb folder, however nothing is showing up in the sensors window.

I can't see any signs of errors in Meteohubs logs (but I'm not sure if there would be).

If you'd like to take a look Boris you are welcome. Access details same as for your last visit. The running copy of the plugin is at /home/1wire/poc. The c++ code can be found in myweb/proofofconcept.c.

I'm not sure why I didn't think to look there before but the thb9 1-wire sensor is appearing in raw data (and in the Insepect Data window), e.g.

20090210083522 thb0 149 58 0067 9870 3 9988
20090210083523 wind1 45 0 6 0150
20090210083529 wind0 32 0 0 0150
20090210083531 thb9 150 57 0000 10038 0 10038

Perhaps I am misunderstanding something by expecting it to appear in the Sensor window?

PS. Dewpoint is zero because I'm not providing that at present. Maybe I should just use a single zero?

Now tweaked to just use a zero for dewpoint, and added th29 & t29 based on the same data:

20090210090823 thb9 166 55 0 10040 0 10040
20090210090823 th29 166 55 0
20090210090823 t29 166

None of those are appearing in the sensors window (but all are getting into raw data - the above quote is a copy & paste from the 'Inspect Data' window).
If I place text such as [actual_thb9_temp_c]into a html template it doesn't result in data values when the page is viewed in a browser.
[year1_thb9_temp_c] does however give a value - presumably as a result of a recomputation?

I did wonder if maybe I needed to proactively add the sensor to the "Additional IDs to be evaluated" section of the Sensors window so I used the drop-down to select and name a thb9, then Saved.
The result of that addition was just that I now have that line plus the usual blank one in the "Additional IDs to be evaluated" section (and of course the Save has caused Meteohub to do a full recomputation...).

It's probably something that I'm doing or misunderstanding, but at present I can't see what.

Oh, Well. Off to work...

PS. I'm using rc6.

Problem:
diagrams show sealevel diagram and press diagram show the same curve.

My station: TE923 / NSLU2 / Meteohub 4 RC6

This is shown in all-sensors.txt:
actual_thb0_press_hpa 942.8 <-- correct!
actual_thb0_press_psi 13.67
actual_thb0_press_mmhg 707.1
actual_thb0_press_inhg 27.85
actual_thb0_sealevel_hpa 1006.9 <-- correct !
actual_thb0_sealevel_psi 14.60
actual_thb0_sealevel_mmhg 755.2
actual_thb0_sealevel_inhg 29.75

but the diagramms for "press" and "sealevel" show exactly the same curve, only the curve for "press"...
seems there is no correction with "stationshöhe" in diagramm writing...

Besides this thanks a lot for your exciting work !

data coming in trhough plugin is not displayed at sensors page at the moment. It is just logged.

Specifying additional sensor ids for it make data accessible for computation of graph data and all the other data consuming processes.

I will check the sealevel graph thing during the week end.

That's fine.
I just wanted to be sure that it was working as you expected.

Excellent.

I now see that things like [last60m_thb9_temp_c] are being evaluated. :)

I really like this feature... :cheer:
... and as a side effect I know a whole lot more about Debian/Linux than I did a week ago! :laugh:

Not sure if this is only here, but I'm finding that sometimes Data Logging fails to start cleanly with

logger (12.02.2009 10:11:38): error while doing bind (port 5500): Address already in use

[admin]

rc7 should solve the sea-level issue. please give it a try.

[meinmotion]

I'm using a Davis Vantage II with a solar sensor but the solar sensor data is not logged when I inspect the data. When I output the sensor data as all_sensor.txt the values are in the file. I'm using the latest RC7 version now but no Solar data.

[darren7303]

Have installed RC7 (twice) my historical data is not being shown, both in the dashboard and to WD Live.

I'll try reselecting the station and a re-compute just incase.

[darren7303]

As an update, I have deleted and re-installed the weather station and recalculated the data.

I now have no historical data showing on the dashboard or for WD Live.:huh:

I'll re-install rc6 after work tonight.

[admin]

Not logging solar data is a bug, that will be fixed in rc8, coming soon.

historical data needs recomputation to be finished. if that does not help, giving me access to your rig might be the most straight forward approach, as things look ok on my systems.

rc7 dashboard only showing zeros in historical rows here too. The current figures row does however show correctly.

Graphs and html template seem to work fine.
