Hello Werner and team.

We have got the Te Whaiti School NZ weatherstation pretty much going ready for next semester thanks.

Thanks to all for the help you have given us (via our ENGLISH topic on the Webcam forum). We got the FTP to our website going on our develoment site but the school has just changed its web ISP / internet access and some server configuration port allocations remain to get the site finally sorted. We still have to get the webcam going but that is not a big or urgent issue.

The configuration questions we hope someone else's experience may help us resolve are:

1. Handling daylight saving.
NZ changed its dates so the IROX firmware NZ code setting is no longer right. To help overcome this IROX now has a further timezone code ON - which turns the clock back one hour allowing NZ (and others) to toggle using codes ON and OF on the console in the meantime. It would be great if this additional code was added sometime into the weatherstation config menu Werner so it could be set from WsWin please??

2. Exporting monthly files
When using this though it does something as if its working when the the command is used, nothing seems to go into the Export directory. Could it be Werner that the v2.74.0 version we have installed is a demo and not a registered version to block this??

3. UV sensor status
The UV sensor is working and appears OK on the Status of weather station values and reception displays but does no show in any of the database displays or reports. Is there something we are missing in the setup here??

4. Special sensors:
We measure temperature of our black body sensor in a jar to capture solar radiation. Setting this under Solar as a difference sensor we are getting the differnce temperature relative to outside temperature OK. (it reaches at least 20 degrees on an Autumn day) We are now wondering if and how we can we set the thresholds on this to use it to allow WsWin to calculate sunshine hours. Has anyone else done this who can help us please? Alternatively could the sunlight readings be taken off the UV sensor somehow??

5 Solar Energy in versus earth radiation out = net Balance.
We can calibrate our black body temperature differnce by means of a resistor network ( heater) glued the rear of the black sensor plate - eg temperature differnce vs Watts per m2 to estimate solar energy inflow. Has anyone used the negative temperature difference observed on a clear night with a few scaling factors to try to calculate an approximate net earth energy flow balance for any location (eg maybe we would expect it to be positive by day and negative by night ... also over each 24 hours increasingly net positive as we move into summer and increasingly net negative as we go into winter) ?? Could be a good way for students to get an idea of nature's mechanisms and balances around global warming, climate change and seasonal wind flows - Trade winds etc


I guess all these questions will probably have been asked and answered somwhere in the Forum in German. If so, we hope someone might be kind enough to translate this for us or give us some other advice please. The school is 4.5 hours drive from Auckland where I live, so I can't easily check my setup but any answers / suggestions will help next time I travel there.

Hello,
question2:
The export-file has got a name like Expmm_jjcsv (for April it's Exp04_09.csv) and it is stored in the program-directory, not in th eexport-direktory. Normally in c:\programme\wswin
The next has nothing to do with your question, but the actual version is 2.94.3 and it would be a good idea to use this version.

@Peter,

1. I have no information of this - could you give me more info ?

2. the default export file (ws_newdata.csv) ist stored in the Wswin folder.

3. is UV set "available" - under Weather station, Available sensors ... ?

4. see my setting in the program help

Alternatively could the sunlight readings be taken off the UV sensor somehow

never: sunlight and uv are different things

Hi Werner, Thanks for the information.

1. Your Weatherstation Adjustments/console screen for the DST options as well as the defined national zones ( eg SZ is NZ) has an entry
NO DST =no = places that do not observe DST, but does not have the second entry
ON = always add 1 hour with local standard time
(This is on the last page of the IROX manual)

For new countries (or those like NZ that have changed DST dates since the IROX firmware was written) the manual change can be made by swapping between ON and NO.

2. On my copy at home Export of the files to to the folder Alldata seems to work OK thanks - will be able to sort at school

3. Will check this at the school should both UV-X and UV be ticked.. How do they differ??

4. Will check this again. If I tick "difference temp" and specify the correct sensor as I have, does this automatically cause this to be the parameter that is used to monitor sunlight. I see it has a max value in W/m2 and kLux displayed. How is the scaling for that setup for our homemade black body temp sensor? or is it automatically read and set after some time, so that the % figures required to be input for the limits below are set relative to that?

I am now away for two weeks so there is no urgency. Peter

Hello,

I think, you don't recognize, that there are many ways to export a file and that the destination differs from what you have chosen.
a) normally, when you do "file - exporting - exporting month file" the destination is the programm folder (as I have already written) -->and this is the normal way to export files
b) but when you do "file - exporting - exporting all month files" the destination will be "alldata" --> this makes especially sense, when you want to change the weather station.

Exporting the monthly file fills it in only up to the current time of the month. We want to export in in a form that every month is trasfered as an Excel file in the school server. Since I have not found a way of exporting "Last months data", in order to get the full months data it seems we need to export all months data to pick the full data for the previous month.

Hello,

Exporting the monthly file fills it in only up to the current time of the month.

That's right and the usual behaviour.
When you want to get a previous month, you have to do the following:
- choose "view - month" and you will see the actual month
- now select the month before with the "back-arrow"
- now choose "file - exporting - month file" and you will get the complete month
