[For 'pollen' I use https://www.weeronline.nl/Europa/Nederl ... on/4057944 as an iframe within Dashticz. Not sure if it has a json or other output.
@Edwink,

thx but I don't know how to process the information from that site given the format it is presented in. For now I only process data that is presented in JSON or plain text format. If required I probably could also add some functions to process XML but processing HTML to get the required information is more than 1 bridge too far for my programming skills.
Too bad, but understandable. Will keep using it the way it is now. Who knows, someone else can work this.

Feature request:
It would be nice if the script created a virtual device or environment variable which contains the amount of rain fallen in the last 12 hours.
So I can use that to decide whether or not my garden irrigation should turn on today or not.
Then I would combine that information with the amount of sunhours of (say) 25+ degrees celcius and I can water my garden only when needed.

My preference is to do this with this (separate) script that can also be used by anyone who updates their rainsensors by other scripts / hardware.

@EdwinK, No rain should not cause this error.
Could it be that the deviceName or IDX for rainDevice you are using is not of the type rain or that it is just created and /or no values are in the history in the hours to be reported (yet) ?

If it is of type rain and already in use for > 1 hour can you check the result of

Hi,

A few times per day I get the following error message:
2018-07-17 14:48:05.367 Error: Error opening url: https://gadgets.buienradar.nl/data/rain ... 2&lon=5.47
2018-07-17 14:48:05.730 Error: dzVents: Error (2.4.7): WUS: [0006] Er is een probleem met inlezen van de data; controleer wat er fout is gegaan. in:WUS_rainForecastResponse, Error: 11699956
I assume that certain data is not available when the script runs. Is there a way to prevent this. Perhaps use the old data if the new is not available?

Kind regards, Rob

@schulpr

Rob, the first errormessage is from the main domoticz process telling us that the url could not be reached. I see this a couple of times a day. dzVents cannot check before firing the openURL that it will be successful so I cannot think of a way to prevent this.
The second errormessage is from dzVents telling that the return from the openURL contains no valid data and could not be processed. The design choice for this script is to ignore this and leave all values in the virtual sensors and switched as they were set in the previous run.
I assume that this is relative safe choice if we don't see these error messages flooding the logs.
Hope this clarifies

Hi @waaren,

Thanks for clarifying this. It's no problem but I like a clean error log .

@Waaren Maybe a idea to have a option to disable all error logs? Because script is running perfect only sometimes no feedback from Buienradar:

As explained two posts before this. dzVents cannot prevent the "Error opening url:" message.

You can prevent the [0006] errormessage in the log by changing the lines starting with "dz.log(ERR.TRIGGERERROR" to commentlines by adding -- at the beginning of those lines.

Will try this script tomorrow.. Thanks for share. 😉

When its working, i will try to add "pollen" in this script. Can't promise it, i will try it.

Have you entered your location in the domoticz settings ?
If so what do see if you enter

Code: Select all

http://maps.googleapis.com/maps/api/geocode/json?latlng=LATITUDE,LONGITUDE&sensor=true 
(replace LATITUDE.LONGITUDE with actual values) in your browser ?

To answer your questions, yes I specified location in domoticz, and I got a correct result when I tried the googleapis url.

But a night sleep did miracles, error is gone now.

Thanks for reporting !
In that area, the script tries to obtain your address from Google based on longitude / latitude.
The message return is now:

"error_message": "Keyless access to Google Maps Platform is deprecated. Please use an API key with all your API calls to avoid service interruption. For further details please refer to http://g.co/dev/maps-no-account",
as a workaround change line 912 from

Code: Select all

if var.useDomoticzLocation then 
to

Code: Select all

if not(var.useDomoticzLocation) then
I will have to look into that how to solve this. Will do over the weekend

Hi waaren,

first of all thanks for this script. This is very cool and helpful :)

Do you have an update of the previous post? I'm having the same error.

Unfortunatly I'm still in the beginning of the learning curve to lua and dzVents, so I'm not a big help yet ;)

Thanks for your help.

Sorry missed this one until now.
The only way to solve this is by getting a google API key. If you have one I will explain how to use it.
