I use a different script now and i have it working.
But thanks anyway.
Hi Tlpeter

Would you mind sharing your windows script please?

Thanks
Mark
Yeah please ;) Also a Windows user. Have ordered screens but the fibaro module is already installed. So I have al the time preparing the windows script for it.

I have taken the script of tlpeter and made it to my needs.
I have done the following
- Integrate the script with the rain prediction of 'buienradar'.
- made user variables from the thresholds in Domoticz so I can control it from the web interface.

There is a little question. In the settings of Domoticz you can set the langitude and longitude. Is it possible to read this out by LUA?

There is a little question. In the settings of Domoticz you can set the langitude and longitude. Is it possible to read this out by LUA?
Thanks for the script. I tested it (only on temperature).

Outside temp. is 25 degrees. When i set the treshold variable on 30 the screen is Up (off). When is switch manually down (on) it goes up. so thats ok. Because temperature is too low.

But when i set the treshold temperature on 12 degrees nothing happens.... Up or down, the status is ok.

Which blinds switch did you use?? Looks like up/down, open/close on/off are mixed?

Do you have a override switch called "Zonnescherm manual override"? The first time I used it I had the same sort of issues. Then I saw that I don't had the override switch.
When you don't want to use the override script you can edit the code:

Code: Select all

 elseif (otherdevices['Zonnescherm'] == 'Closed' and sWeatherTemp < TempThreshold and otherdevices['Zonnescherm manual override'] == 'Off') then
to

Code: Select all

elseif (otherdevices['Zonnescherm'] == 'Closed' and sWeatherTemp < TempThreshold) then
and the same for the UV check.

I have made a new script with the following adaptions:

- 2 new variables (RainPredThreshold and SolarThreshold)
- Check if UV or Solar is right to open or close the sunscreen
- Check if Rain Current of Rain Predicted is right to open or close the sunscreen
- More loging when debug is on

Code: Select all

For me this would be the latest version because in my case I can not trust on WU of Forecast IO.
When there is a clear blue sky WU sometimes think it's rain. As long as I don't have a dedicated weather station I will leave it like this. If anyone has any comments or want something else let me know and I will take a look into it.

For the people who are interested, I made the rain prediction script usable for Windows. 8-)

Steps to make it work:

- Make a virtual Humidity device in Domoticz and remember the IDX number.
- Go to the following website: http://curl.haxx.se/dlwiz/ and download the needed setup. (x86, x64).
In my case I selected "curl executable", "Win64", "Generic", "Any" and "x86_64" (I use Windows 8.1 64Bits)
- Create A new folder on your Domoticz Computer (For example: C:\Rain ).
- Extract the downloaded "Curl" zip file in this map.
- Make also a new file in this folder called: "rain.tmp"
- Make a new lua file called: "script_time_rain_prediction.lua" Fill the file with the following code:

Code: Select all

Change the following data in your script:
- Change the longitude and latitude to your location. You can find these numbers in your Domoticz Settings.
- Change the path after: "tempfilename" if you have chosen another location.
- Change the path after: "read = os.execute: if you have chosen another location.

Greetings.

Just wanna say thx for the script.
Gonna use it for my Garden Irrigation.
Why irrigating while rain is coming up ;-)

It's a great script!! And two nice thresholds added.
Now some playing with the settings to get it right.

Thanks Luuc and Hansbit

Hi Hans,

I've tried to send you a PM (in Dutch) but it seems that I can't get any messasges sent. I'm not familiar witch lua just yet but I would like to get data from Buienradar as well to add to my garden irrigation system and moisture sensors already in place. Can you put me on the right track about how to integrate this in domoticz exactly?

Thank in advance!

I would like to use the outcome of the rain value/virtual humidity sensor in blocky. But for some reason blocky doesn't seem to respond to the value of the virtual humidity sensor. anybody has an idea?

Can you post an example of your Blockly?

Just a plain and simple blocky just to test

I think you need to compare something like in my Blockly:
And I have my doubts about the "open" command.
Maybe test to write something in the log file or send a notification.

Timer Regen = virtual switch that is on when there is rain and off when there isn't. (needed for not creating loops in blockly).
Screens Dicht = Virtual switch for indicating if the screens are closed. (needed for not creating any loops in blockly).

I've tried to send you a PM (in Dutch) but it seems that I can't get any messasges sent. I'm not familiar witch lua just yet but I would like to get data from Buienradar as well to add to my garden irrigation system and moisture sensors already in place. Can you put me on the right track about how to integrate this in domoticz exactly?

Thank in advance!
Maybe you could try my script, just finished it and does what you want...

Thanks! Haven't worked with lua before, so I guess there is a lot to learn but this will help me for sure!

Posted a install instruction in the Wiki

Please note that a threshold of 70 is (in my opinion) the best value to trigger for rain.

Why a threshold for 70? Then it would already be raining right below 70? So that would be to late

With lower values to trigger for rain you'll get too many false positives. Even on sunny days with clear blue sky, Buienrader sometimes reports values like 35 or 40.

The wiki script gives me the following error: Error: EventSystem: Lua script did not return a commandArray
Any idea what's wrong?

Do you have this line at the bottom of the script?

Code: Select all

return CommandArray
