CWOP Forum / Downloding data from CWOP since 2013
« Last post by tichugh on Today at 06:58:21 AM »
Hi,

I am trying to download the data via http://www.findu.com/cgi-bin/wx.cgi?call=M1VPN&last=240 and varying the number of hours e.g. 44000, but it doesn't generate the data. Is there any way I can download the data for example May 2013?

good afternoon

using the improved script courtesy of andrew billits and now with improved css design color coded and slimmed down svg icons also has new option to switch in or out via setup screen,if you are not interested or dont have a requirement / hardware.

*** important many main files updated to reflect the new option so please dont take any shortcuts thats 90% of the problem in every email.  some older files were removed which basically were duplicates.

WLIP updates WeatherLink.com display around every 60 seconds, which by default is not configurable for a stand-alone WLIP. Archive interval is something the user can define which is uploaded to WeatherLink.com every 60 minutes. This archive interval (as set by the user) is also what WeatherLink (the software) downloads to a PC on demand.

With Meteobridge a window has to be allowed for WLIP to upload to WeatherLink.com and this is controlled by Meteobridge and I would recommend the WeatherLnk.com display is updated every 5 minutes which allows MB to concentrate on other networks which can be updated to a low as 5 seconds. With MB WLIP still uploads the data archive (if activated) as normal every 60 minutes

I guess as a new Weatherlink user this is what confuses me. So WLIP updates the ďliveĒ weather seen on WeatherLink.com every 60 seconds but there is an archive sent every 60 minutes? If WL.com is getting data every 60 seconds why arenít they recording it, what is the ďarchiveĒ? Whatís the point of it?

Also it seems my ďarchiveĒ is showing a data point on the charts every 30 minutes. Iím a pro user, how do i change it to every 5 minutes which I think I can? My understanding is I can do it on my Vue console but how? Iím a Mac user so I donít have WL software to control the WLIP with and I canít see any settings for 5 minute data points in any options on WeatherLink.con.

Sorry for so many questions, Iíll have 100 more when I try to setup the Meteobridge next week lol.

Sweet!  Any idea on pricing?

Pricing:

WiFiLogger price is $169. I think resellers will sell it with discount. You should expect -15% at the beginning.

There will be second product. WiFiLogger Lite with price $109. Also expect -15% at the beginning.

WiFiLogger Lite will be simple data logger like RS232/USB, it will need running computer to download and share data, but via WiFi.
Good to work with Cumulus or WeatherLink. That becouse is an Internet technology, you can still share data regardless of distance. Only one connection at same time (console limitation).

Please note that it comes without WeatherLink.
So you need to have original RS232/USB/IP data logger which has licence for WeatherLink.
Cumulus is a free software.

.... Quick question... how can I tell if I am on the 1 minute sample rate for the WLIP? My understanding is somehow I could check on the console if I am not a PC user, but isn't it the default? I want to max out the sample rate to the extent the stock WLIP can handle at least until I bring the Meteobridge into the equation...

i think this just fantastic news i have a redundant vp2 project simply they reluctantly did not budget for the additional cost for the logger and computer .

as this project runs with a small computer UPS in line im really looking forward to the cost of your product and preying itís substantially better priced than a official logger package.

kudos to you ...

is it better that the davis IP data logger in relation to more than 1 connection?

It is not a problem of any data logger. Console has only one connection.
You can use only one software at the time.
If you are using WeatherLink then you can't use Cumulus.
WiFiLogger internal software is also working like WeatherLink or Cumulus. So collision may occur.
If WiFiLogger is uploading data, then you just can't connect with Cumulus to console throught WiFiLogger.
If you upload to WU every 15 min using internal WiFiLogger software, then you have 15 minutes free time between uploads.
With RapidFire which uploads every 3s. You have only 2.5s for Cumulus software.

I will add button to make pause for internal software to stop uploading data and clear this channel for WeatherLink/Cumulus to allow to download archive data.

Original IP Logger send data every 1 min. There is also problem with collision, it's tricky to download archive data, becouse full reading takes 2 min 15 s. And there is interaption every 1 min.

I'm assuming that, like the OEM Davis WL-IP data-logger, that *IF* the Console is being powered by the #6625 AC adapter that the internal 3xC-cell batteries are not truly necessary and could be eliminated. Yes? No? Maybe?

Yes WiFiLogger is working like any other data logger. If you have AC adapter plugged that is a main power supply, If you pull out AC adapter then start to work using battery power.
Problem is bigger current consumption. It is bigger than USB/RS232 data logger and equal to IP Logger.

Console without any data logger can work on batteries 1 year.
Console with RS232/USB data logger can work about 3 months.
Console with WiFiLogger/IP Logger can wotk using batteries 3-4 days.

But I have add option to switch WiFiLogger to external power. If you add second ac adapter for WiFiLogger or  you manage to split original AC adapter cable. Then batteries will be not used with WiFi chip.
However, the console is still equipped with the ability to write archived data. So even  if you switch WiFiLogger to external power source life on batteries should be about 3 month just like RS232/USB data logger.

Logic is simple. If you don't have power at home, your router don't have power as well. No internet, no reason to drain batteries.

Original IP Logger also should have that option, becouse it's loosing data.
When you have a storm and you pull out AC adapter and you will forget to plug in. Then after 3 days batteries are dead, and no power.
Common issue with IP Logger.

I give you this option with external power source to prevent this situation. You choose, very convinient internal power supply from console, or external with second adapter, or splited cable.
+ There will be an option to automaticly shut down WiFi chip to save batteries, that option should be good for solar panels.

I am using DC UPS made by myself from old laptop Li-Ion cells. Not perfect but cheap and works fine. I will make some documentation and start separate post with this solution.

Other Weather Station Hardware / Re: Solar radiation sensor, why and what
« Last post by SLOweather on Yesterday at 11:57:15 PM »
With the solar sensor, the console will calculate evapotranspiration (ET), or how much water evaporates from the soil, and how much is transpired by grass. With that number, especially summed over a week, it's easy to make informed watering decisions.
