Hi,

I add an line so the log is more compleet.
..regen.. is the function from your script.

The last time the script gives an strange result:

2016-12-03 15:15:00.854 LUA: Regen verwacht: nan mm binnen 20 minuten.
And the switch in continuos ON.

I cannot found where the nan is generated. Any ideas?

What is the content of the file downloaded by the script? (rain.txt)

I think the nan is because the value is 0 when there is no rain predicts.
https://en.wikipedia.org/wiki/NaN

Here is the complete code
I'm not at home right now so I cannot view the rain.txt file. Will follow.

When I enter the url in explorer there is data.

Put debug on to TRUE

Also I think your URL need to be:

http://gadgets.buienradar.nl/data/raint ... 5&lon=5.11

Set your
lat to 52.65
and
lon to 5.11

I think they changed something, you get an MOVE PAGE is you used the more advaned lat en lon.

I tried this script today and got it working after a change. Thanks for the nice work!

As already been said the URL needed has been changed,
It is changed to this one:
url='http://gpsgadget.buienradar.nl/data/rai ... 5&lon=5.11'
(tried it in the webbrowser and checked the file, this is working now as I see values for one hour for every 5 minutes in /var/tmp/rain.tmp)

lat and lon are auto rounded in 2 decimals so more decimals in the variables are useless.

what am i doing wrong?

Maybe you can post your script?

You say that you "Rain Expected" Virtual Switch remains 0mm. Its a Switch so you can only set it "On" or "Off". As the script does at the bottom.
When was the last time this switch has changed in the log?

FYI

I saw errors like these in the logging from time to time..
So I added a 5 seconds timeout to the curl command.

I noticed that you use a temp file to write data to.
Just to make you aware that this is not needed at all i post my sollution around that ... ( I hate writing temp files for obvious reasons)

function to read directly any page into a string : And then in you following code you can do (just an example) : Content will contain all data that you will need to split into a table to manipulate.
In the table rain {} you will find rain, In the table rtime{} you will find corresponding times. Hope it helps you all to avoid writing unneeded files

Can someone explain how to create a text switch with rain expected, i can't get it to work. I use the latest script but i only have an on/off switch and a print in the log but i want this in a text switch.

I have included this script in events system @lua and works perfect

Edit;
Get it working

Thx for the script.
In addition to the previous posted i added 2 extra virtual rain expectation widgets.
-> 30 minutes -> 60 minutes -> 120 minutes
And set the script to update every 30minutes.

optimised script

I have a problem with my rain script, especially with the text switch which never changes.
this is my code. this is my error Does someone have any idea how to solve this?

this is my error

 2017-04-18 21:05:00.479 Error: EventSystem: in /home/pi/domoticz/scripts/lua/script_time_rain.lua: /home/pi/domoticz/scripts/lua/script_time_rain.lua:165: bad argument #1 to 'sub' (string expected, got nil)

Does someone have any idea how to solve this?

Did you changed the buienradar url as mentioned earlier?

Maybe stupid question, But whats script filename ending? .ph .pl other?

Siewert308SW wrote:Thx for the script.
In addition to the previous posted i added 2 extra virtual rain expectation widgets.
-> 30 minutes -> 60 minutes -> 120 minutes
And set the script to update every 30minutes.

None of those but it is a LUA script.

@poudenes
It's a Lua script.
But forget about the script i amended.
After a closer look it aint working as i intended.
The 60 and 120min forecast are printed but are presenting the 30min prediction.
Need a closer look.
