Real-time solar data : azimuth, Altitude, Lux sensor... [closed]

[Egregius]

Is wunderground pretty accurate and reliable?
Openweathermap isn't. I get readings like 18.6°, one minute later 19.2, then again 18.6, again 19.2,...
During daytime I now use forecast.io but the number of request is limited to 1000 per day for a free account.

[trixwood]

I was looking at cloud sensors... this popped up:

http://www.noao.edu/staff/gillespie/pro ... ector.html

could it work?

it looks like all it is, is this sensor https://www.adafruit.com/product/1330 sandwiched between two aluminium plates.
And then measure and mapping out the voltages to actually readings.

[Egregius]

You also have cloud prediction at forecast.io and openweathermap.

Not everybody have a working internet connection on the location they run their stuff...

What do i need to do with data?
Fill in  22.00000000

Only my api [ i reset him] is counting..:
Where can i search ...

you can look up the long, lat and altitude here, I think: http://elevationmap.net

       relativePressure = jsonLocation.current_observation.pressure_mb   -- if you have an another way to get the Pressure, (local barometer ...) then you may optimize the script and avoid the call to api.wunderground)
  

without weathe underground you need to repalce that with:

Code: Select all

relativePressure = 1012

or read it from a pressure sensor...

That yould fix your nil... now I am also stuck on the cloud coverage not coming in....

How can i read it from a pressure sensor?
And where and How to fill in?

Well it crashed for me on:

Code: Select all

       -- if (DEBUG == 1) then
          --local WMOID = jsonLocation.current_observation.display_location.wmo
       -- end

so i commented that out...

My lux sensor is called "Sun Lux", so change 'Lux' into the name you have chosen yourself.(around line 190)... since it does not use the defaults idx but a name...

Code: Select all

	if tonumber(otherdevices_svalues['Lux'])+round(weightedLux,0)>0 
-- No update if Lux is already 0. So lastUpdate of the sensor switch will keep the time of day when Lux has reached 0. (Kind of timeofday['SunsetInMinutes'])

- So to get it working... setup the virtual sensors
- use a time lua event with the wiki code...
- Fill in the default value (idx, long, lat, etc... put debug=1 to see nice values in log for testing..)
- Use to look up Station ID in the netherlands:

http://www.ogimet.com/cgi-bin/gsynop?la ... =18&vsg=Sg

You could use 06260
- Remove weatherundergroudn api, and use a pressure sensor of domoticz***
- Remove the jsonLocation thing code line... (whatever it is...)
- Change the name "Lux", to your sensor name around line 190 (somebody should fix this... it leads to confusing...)

*** (much beter solution anyway, if you are going to use weatherunderground then do it through domoticz hardware and read that value from there...)

and whalla!

mmm
Your are FU^*^*ing good.....
Only... you are going to fast for me..

Please your code here??

Look for the: VERANDER HIER what you need to change... (throughout the code, thus also at the end of the code
If your sensors are correct and you make it a time,event... it updates every minutes...

Stil that relative i am not good in math..

[Derik]

And Trixwood how did you name the Dummy's..
In the wiki are the names different...
Sun Azimuth or Solar azimuth and D or degrees
Sun altitude or Solar Altitude etc etc etc..

i just setup weatherunderdround...I gonna find out,
in the mean time does it run with 1012 as relativePressure instead of the sensor...??

Ok, so that works... now for the last part if you use the sensor from Weatherunderground hardware:

instead of:

Code: Select all

   relativePressure = tonumber(otherdevices_svalues['Pressure SENSOR']) 

use:

Code: Select all

      temp, hum, uv, pres = otherdevices_svalues['Weather TempHumBaro']:match("([^;]+);([^;]+);([^;]+);([^;]+)")
      relativePressure = tonumber(pres)
 

Where "Weather TempHumBaro" is the combined temp/humidity/pressure sensor so we have to decode it...
