updateWeatherSensors (yet another buienradar script) [SOLVED]

[schulpr]

@waaren,

Properties of the file: 0644
dzVents version 2.4.4
I'm on a PI2
Domoticz beta 3.9227

Hi waaren,

When I put the settings directly in the dzVents script it works flawless

Kind regards, Rob

[waaren]

Hi Rob,

thx. but if devices are entered as numbers it will also work using the setting file.

Again many thanks for testing.

[schulpr]

Oeps, I missed that. I just copied my settings into the new settings file. Thus wrong . Everything works fine now.

Thank you for this great script. Maybe you should consider to make the settings file the only method for the parameters.

Keep up the great work!

Kind regards, Rob

hi All,

I have add the sensor types. But don't know that type of sensor "Rain Rate" will be?

Code: Select all

[waaren]

rainRate is type rain (regen)

[poudenes]

Thanks

I see that the Rain / Rain Device is not updated. Now its red.

And moved the weatherSettings.lua file to

/home/pi/domoticz/scripts/dzVents/modules
instead
/home/pi/domoticz/scripts/modules

When using the last one i get a error that my weather station was not set.

[poudenes]

Will you also add Solar Data? i have a script running to get the LUX level. Would be nice to have this in your script as well. So i can use 1 script for Weather forecast, Rain Forecast, Sun Lux level etc etc.

[waaren]

if solar data is available from buienradar or any other public website I can/will add it.
location/name for setting file is "domoticz dir"/scripts.dzVents/scripts/modules/weatherSettings.lua
Time between device updates even when no change is set by forcedUpdateMinutes in weatherSettings.lua

[schulpr]

Hi,

I would like to use the value of the rain prediction in another script but I can't see what type of value that it is.

local buienkans = domoticz.devices('Regenhoeveelheid 1u').value I also tried other parameters like level, rate.

Does anyone have an idea? (Or even better, a solution )

Kind regards, Rob

[waaren]

@schulpr

hi Rob,

the device is a custom sensor. You must use .state to read its value.

So for you:

local buienkans = domoticz.devices('Regenhoeveelheid 1u').state

[schulpr]

Hi waaren,

Thank you. That was the only one I didn't tried...

Regards, Rob

[waaren]

Hi waaren,

Thank you. That was the only one I didn't tried...

Regards, Rob

you can always use the dump() method to find out what to use

domoticz.devices('Regenhoeveelheid 1u').dump() will give a lot of information

Hi Waaren,
Thanks for sharing this great script.
I installed it and it works fine for Rotterdam and Schiphol.
But when I use IJmuiden or Wijk aan Zee I get an error message:

I run Domoticz V3.9208 on a Pi3B, booting from an SSD.

Hi Waaren,

But when I use IJmuiden or Wijk aan Zee I get an error message:
------------------------------

The problem starts with that this weather station does not provide a value for "luchtdruk" (barometer)
Having said that the script should check that and at least present you with a message when LOG_DEBUG is active.

I will post an update later today with this and other checks and more user controllable settings.

[Bufoto]

Hi Waaren,
thanks for your quick reply.
The strange thing is that the Buienradar site does give the 'Luchtdruk': https://www.buienradar.nl/weer/ijmuiden/nl/2753376
I will wait for your update and test it again.

@Bufoto, I get the data to feed into the script from https://api.buienradar.nl/data/public/1.1/jsonfeed
For IJmuiden it returns

"windrichtingGR": "240",

[Bufoto]

@Waaren: Strange that the info is available on the buienradar website, but omitted in the jsonfeed.
I will send them a message and ask them if they can add that data in the feed.

[waaren]

New version available; see first post here Latest version 0.20180423

Some additional user specific settings. Both files (main code and user settings) are in the attached zip
Added experimental Lux (based on Solar Power) this one still need a lot of work so do not rely on it.
Execution frequency controlled by user settings. Read the comments in the usersetting file

Thanks again. Like the Lux stuff, so I hope it will stay in.
