I'm also getting the updateWeatherSensors:1195 error.
How to prevent of fix it?

Look here to see what is the cause of this error and for a howto get a google API key (effectively free)

I posted a new version (0.20181204) This version will check if you entered a google API key and use that to get your address, based on your set latitude / longitude, from google maps.
If you don't have this API key it will skip this part and assume "Nederland" as your address

I'm familiare with the GMap api, but I couldn't find a way to add the api to the previous version of the script.

Couldn't find it that fast in this topic/forum, but which values are based on the KNMI weatherstations and which are based on Buienradar API/calculations? For instance expected rain is, as far as I known, not available on the weatherstations so its must come from the Buienradar API.
So if its from the API, then its location is based on my Lat/Lng? So rain calculations are based on my domoticz location and not on the KNMI weatherstation location?

Or I'm i Wrong?

Thanks for the update and it working like a charm!

You are right. Thanks for pointing that out !
Rain forecast devices (text, alert and two custom sensors) are always based on the result of the call to https://gadgets.buienradar.nl with the lat/lon from domoticz settings.This is a fault in the logic. I have corrected it now but still testing. Will post an update later today.

If useDomoticzLocation is set to true, all other devices are based on the weatherstation information ( buienradar )
from the station nearest to this lat/lon or (optional) if the required part of the data is not available at that station it will travel the list of weatherstations from nearby to further away to find a station that does have this part of the data.
If useDomoticzLocation is set to false, the information will be extracted from the named weatherstation.

The call to Google Maps (which now must use the GMap api ) is only used to translate the lat/lon to a more detailed than "Nederland" human readable address.

[Freemann]

Thanks for the explanation and great to read that rain information is really local!

Would it be possible to use the script without the Gmaps call? So the use post/add the looked up data to the script itself?

Not sure what you mean with "post/add the looked up data to the script itself?" Please elaborate.
In the latest update it is possible to skip the Gmaps call by setting googleAPIkey = false in the setting file.

[Freemann]

You wrote;
"The call to Google Maps (which now must use the GMap api ) is only used to translate the lat/lon to a more detailed than "Nederland" human readable address."

So the API call is used to get an Human Readable Address.
For what is that address used and why get it through a API call and not let the user set it through a variable in the settings script?

[waaren]

For what is that address used ?

for Display only

and why get it through a API call and not let the user set it through a variable in the settings script?

Same reason as why I get the lat / lon from domoticz settings and not from the settings script. Because it is possible. Easy to add that as an option. Just ask.

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.

Thanks a lot Waaren. I upgraded to the latest version, got the google API key and it all works fine now.

Hi All,

The script special part LUX is not working. Or seems not to work. The values are change so fast from around 2000 lux to 0
So in past Lux values go low from 1000 >900 >700 > 600 etc... till 0. For me when lux is below 696 then turn on lights.

Also the high values are to high I think?

The LUX function used in the script is based on the solar radiation data from buienradar and I explained in the comments (line 24-30) that this was experimental and especial in the higher ranges not very accurate. I certainly would not want to control my lights in the house based on these values. In fact I use the production of my solarpanels to determine the amount of light.
If you now encounter a different behavior then a couple of months ago the only explanation I have, is that you receive different values from your nearby weather-station for solar radiation. I see more or less comparable values this year then I see over last year.

I hope you guys can help me.

After a fresh install of Domoticz, I am trying to get the updateWeatherSensors script up and running again, but because a (for me ) mysterious reason, the data is not coming into Domoticz.

The Domoticz log isn't showing any errors.

I already modified the permission for the weather scripts and _data_updateWeatherSensors.lua, so I think that shouldn't be a limitation too.

Does anyone have any idea why the data isn't loaded into Domoticz?

[waaren]

After a fresh install of Domoticz, I am trying to get the updateWeatherSensors script up and running again
The Domoticz log isn't showing any errors.

First question that comes into my mind: is the event system and dzVents enabled in your newly setup domoticz ?

Yes, both the Event System and dzVents are active.

In the log, it gives the following line:
2019-07-29 08:55:00.344 Status: dzVents: Info: WUS: ------ Finished updateWeatherSensors.lua
So I guess it can find the scripts as well.

[waaren]

OK.
Can you change line

        logLevel                  = dzW.LOG_ERROR;              -- DEBUG,INFO, ERROR

to

        logLevel                  = dzW.LOG_DEBUG;              -- DEBUG,INFO, ERROR

In the file <domoticz dir>/scripts/dzVents/scripts/modules/wusSettings.lua ?

When the script executes it will show a lot more information in your domoticz logfile

Thanks for your quick reply! It is showing more information indeed:

In the log, the system is asking for the Google API key, but I thought it was not necessary?

[waaren]

asking for the Google API key, but I thought it was not necessary?

Cannot remember. But will have a look later today.

[waaren]

asking for the Google API key, but I thought it was not necessary?

I checked and indeed Google API key is nice to have but latest version of the script (20181205) should also work without one. Only thing missing will be detailed address information.
Please share your settings file if you don't see anything else in the log (blank out any private stuff and feel free to PM).

Hi,

I started with a fresh installation but getting this error now:

2019-08-07 08:24:01.075 Error: dzVents: Error: (2.4.26) WUS: An error occurred when calling event handler updateWeatherSensors

I tried changing the station names "Lelystad", "Meetstation Lelystad" (called like this in the JSON info) and "true" so the location info from Domoticz is used. No solution so far.

Any ideas, tips?

Kind regards, Rob

myWeatherStation "Lelystad" (with the quotes) or useDomoticzLocation true (without quotes and when location is set in domoticz setiings) should work .
