Update to Meteohub V4.7d (NSLU2, x86, SheevaPlug) brings these features:

Reports max gust of last 10 minutes as gust speed to weather network "awekas".
Changes weather station software identifier for weather networks to "MHxy" (where xy=47 stands for version 4.7) schema. Same schema applies to Meteoplug, where identifier is "MPxy".
Adds experimental support for plotting graphs based on evapotranspiration (when your Vantage reports this value).
Adds support for Vantage 3rd party "XBP Datalogger" from Fjord Technologies.
Fixes a rain fall computation bug when importing data from Meteobase. Adds support for Meteobase data with UV sensor data.

seems with 4.7d my CWOP info shows wrong station type. was working correct with 4.7

Just to document your issue, these are the raw packets received:

Before the update:

After the update:

Thanks! (also to YJB)

BTW:
Is this Datalogger from Fjord Technologies also supported?

Hello

There is a bug in evapotranspiration data

Yesterday my console gave vp2 0.5 mm and 2.2 mm Meteohub Chart

Here is my config on Meteohub

Posted: **Mon Feb 14, 2011 8:10 pm**

I agree, I see the same over here:

ET Graph according to MH

: MH_ET.jpg (90.2 KiB) Viewed 12273 times

ETH Graph according to WeatherLink

: Davis_ET.jpg (76.71 KiB) Viewed 12273 times

To help debugging this I've created a table, its shows
- Date in yyyymmdd<timestamp of last recording>
- Raw value as seen in the raw data file
- Converted from Inches to CM (The Davis loop reports in fractions of an inch)
- Value seen on the Davis Console

: MH_Raw.jpg (37.94 KiB) Viewed 12269 times

As one can see the Davis Console seems to do some odd rounding.

[Update]
I was also wondering why the value reported on Feb 13 was so high, it turns out that Meteohub did something very odd during the update going from 4.7c to 4.7d:

Raw values just before the update

Code: Select all

20110213202951 sol4 0 17
20110213203053 sol4 0 17

From the log the startup message after the update (keep in mind that the raw data is at GMT)

Code: Select all

logger (13.02.2011 21:33:03): data logger (version 4.7d, build 5164) started.

Raw values after the update

Code: Select all

20110213203338 sol4 0 43
20110213203439 sol4 0 43

Maybe someone else in an area with a bit more sun can do the same, so that we can compare, and help Boris with this puzzle?

looks like computation does not reflect if rain total has been set to 1/10 mm or 1/100 inch.
will be fixed with next update.

Thanks Boris for looking into this.

But what about the sudden change in raw data? This is not touched by a recomputation, let me show you the entire records:

Code: Select all

20110213202123 sol4 0 17
20110213202225 sol4 0 17
20110213202327 sol4 0 17
20110213202429 sol4 0 17
20110213202531 sol4 0 17
20110213202951 sol4 0 17
20110213203053 sol4 0 17

< 4.7c to 4.7d update>

Code: Select all

20110213203338 sol4 0 43
20110213203439 sol4 0 43
20110213203541 sol4 0 43
20110213203643 sol4 0 43
20110213203745 sol4 0 43
20110213203847 sol4 0 43
20110213204542 sol4 0 43
20110213204647 sol4 0 43

Which set of records is wrong?

Posted: **Mon Feb 14, 2011 11:37 pm**

it directly has effect on data logging (no recomputation involved).

I uploaded a new 4.7d version.
If you like, please give it a try.

Hi Boris,

Things are still not looking right after applying the fix:

For yesterday the graph reports approx 2.4 mm
Davis console reports 0.8mm
Davis Weatherlink reports 0.71mm (which might be rounded up to the console to 0.8mm
Lookig at the raw data file I've got a value of 56 at the end of the day
20110215230115 sol4 0 56
20110215230217 sol4 0 56

Is there any way that we can debug this and record the values received from the console when issuing the loop command for some time?

As usual I can give you access as well, but I don't mind installing some debug code myself.

At my station, the VP Console shows actual 0.3, in the actual_sol0_evotranspiration_mm is a value of 2.4

Posted: **Fri Apr 08, 2011 11:39 pm**

Hello,

I have always the problem despite the new updates with evapotranspiration

Posted: **Sat Apr 23, 2011 6:13 pm**

Hi Boris
I'd like to remember on this subject. Do you have any idea about the different between the value from Meteohub (at me actual 25.6) and there from the Console (at me actual 3)?
Thanks for a short answer...
