Announcing OpenWeatherMap binding for Eclipse SmartHome / openHAB

thx @cweitkamp. I’ll try my luck

I installed the OpenWeatherMap-Binding via Paper UI.

As one can see, a lot of the items are not filled with values.

2018-11-21 23:04:40.231 [WARN ] [mon.registry.AbstractManagedProvider] - Could not update element with key openweathermap:weather-and-forecast:api:local in ManagedThingProvider, because it does not exists.

While startup is running (and later) there is a Warning Message which i can not handle.
And when i made a change in the Thing-File an error is spit out. (i can’t find duplicate channels)

The Api-Key is valid and in use to retrieve data with http.cfg and extract it via JSONPATH, like this

String              CommonId_owm              "Himmel owm [%s]"                                     <sun_clouds>                (gYahoo)        {http="<[owm_test:120000:JSONPATH($.weather[0].description)]"}

Any hints or ideas what’s wrong in my setup ?

Hi @cweitkamp , thanx for the OWM binding !

I just installed and I will be playing with it the next period :slight_smile:

I have some remarks wrt docs. should I post them here or open an issue on ESH?

Also: If I add the altitude in the location of the Thing, I get the classic ManagedThingProvider WARN. I believe this is because PaperUI “trims” the altitude from the Thing conf page and tries then to update the Thing with only lat/long but it can’t because the Thing is not Managed (see here also: Finally, I got rid of this AbstractManagedProvider warning)

I have the same issue with PaperUI also for the Astro binding (trimming of alt). I think that I should open up an issue for PaperUI…

Results in Warn:

Bridge	openweathermap:weather-api:api	"OpenWeatherMap Account" @ "Weather" [ apikey="abc123", refreshInterval=30, language="en" ]
	Thing weather-and-forecast local "HomeR Weather & Forecast" @ "Weather" [ location=",yy.yyy,0", forecastHours=120, forecastDays=7 ]

Works ok (without alt):

Bridge	openweathermap:weather-api:api	"OpenWeatherMap Account" @ "Weather" [ apikey="abc123", refreshInterval=30, language="en" ]
	Thing weather-and-forecast local "HomeR Weather & Forecast" @ "Weather" [ location=",yy.yyy", forecastHours=120, forecastDays=7 ]


@fibu-freak Do you own a paid account for OWM? If not, the daily forecast will not work.

@Dim Why not contribute your ideas directly? Otherwise share them in this thread.

Yes, could be worth to do some further investigations on that issue. I saw this message from time to time in my life too. But never related them to a geographically location configuration …

No paid account, only free one. Does this mean that my Bridge/Thing is wrong, as using it now ?

So does that mean i can’t use the parameter “forecastDays” or set it to zero ?

Yes, exactly. Unfortunately, that is one of the biggest disadvantages of the OWM API. :slightly_frowning_face:

No Problem at all. It is as it is.
May be you find a solution one day to summarize several values to min/max or something like that within the binding.:wink:

I thought about writing a rule to do this. Scan the 3-hour forecasts for each day to extract the daily min and max temp, maybe average the humidity, develop some heuristic for the conditions, etc., then populate some daily items.

Of course, it would be much better if the binding did this. :smile:

:+1: Great. I thought about too. But to heavy for me.I’m newbie and in my former live i was an accountant (i only know “Excel” and a bit of ERP-Software). So i think it’s not that easy as it seems, as the daily time sections are sliding.:wink:

No, I will not do a research for such a solution inside the binding because bindings are meant to transfer and prepare data from a specific API towards the framework. They should not contain business logic. Therefore we have other tools like groups, rules or transformations. Maybe powerful profiles in the future.

If I should make a proposal I would say create some groups, use the power of the group arithmetical functions (MIN,MAX,AVG), and stuff all items of the hourly forecast into them. Easy without much effort.

For other edge cases you can use rules or transformations.

Sorry, I was just kidding about that. :sunglasses:

It just was an idea of me and i understand the aspects that drives you when developing a binding.
I hope the time will come, when i can handle the binding better. And then i will thinking about tunings.:wink:

hi Christoph,

thanks for the binding.

Unless I’ve misunderstood, are you saying that the binding doesn’t support the 5-day forecast?

I’m slightly confused, as the api will return the 5-day forecast, eg:-,uk

Hello guys,

I´d like to merge the items winddirection an windspeed into one item. What I did is:

String Wind_Geschw_und_Richtung
Number Windrichtung { channel="openweathermap:weather-and-forecast:9ee44fae:local:current#wind-direction" }
Number Windgeschwindigkeit { channel="openweathermap:weather-and-forecast:9ee44fae:local:current#wind-speed" }
rule "Windgeschwindigkeit und Richtung"
  Item Windgeschwindigkeit changed or
  Item Windrichtung changed
  var Number wg = (((Windgeschwindigkeit.state as DecimalType).floatValue)*3.6)
  var wr = transform("SCALE", "wind.scale",Windrichtung.state.toString)

  var String Ausgabe = String::format("%1$.0f km/h aus " +wr, wg)

(thx to M. Spiller for that)

That is working quite well. But I had to create those two items “Windgeschwindigkeit” und “Windrichtung”. Instead I would like to use the two items from the demo.items that I already have:

Number:Speed localCurrentWindSpeed "Current wind speed [%.1f km/h]" <wind> { channel="openweathermap:weather-and-forecast:9ee44fae:local:current#wind-speed" }
Number:Angle localCurrentWindDirection "Current wind direction [%d %unit%]" <wind> { channel="openweathermap:weather-and-forecast:9ee44fae:local:current#wind-direction" }

Those two items won´t work with my rule because of the additions “Speed” and “Angle” respectively. How do I have to change my rule so I can get rid of those two extra items?

Thanks a lot.

I quoted my opening post. The current weather and the 5 days forecast (in 3 hour steps) are available for everyone. The 16 days forecast (in daily intervals) is restricted to users owning a paid account (Startup minimum). The weather-and-forecast Thing provided by the bindings has different channel groups. One for current weather, a user-defined number (between 0 and 120 in 3 hour steps) of hourly forecast channel groups and a user-defined number (between 0 and 16 in 1 day steps) of dayly forecast channel groups. The daily forecast channel groups are removed automatically if the configured key belongs to an unpaid account.

To answer your question directly: The binding supports the 5 days forecast. But only in 3 hour steps unless you own a non-free account.

just fyi: I am going to get a cool HABPanel widget going for this… more news soon :slight_smile:

Hi Leif,

from my point of view it can be done in this way. Please be aware of typos I wrote this down in a second:

rule "Windgeschwindigkeit und Richtung"
    Item localCurrentWindSpeed changed or
    Item localCurrentWindDirection changed
    Wind_Geschw_und_Richtung.postUpdate((localCurrentWindSpeed.state as QuantityType<Speed>).toString + " aus " + transform("SCALE", "wind.scale", localCurrentWindDirection.state.toString))
1 Like

Thats it. I´ve changed the then-part to:

  Wind_Geschw_und_Richtung.postUpdate((localCurrentWindSpeed.getStateAs(QuantityType).toString) + " aus " + transform("SCALE", "wind.scale", (localCurrentWindDirection.state as QuantityType<Number>).doubleValue.toString))

Otherwise VSC displayed an error saying that “Speed cannot be resolved to a type” and scale said: “Could not transform ‘60.0 °’ with the file ‘wind.scale’ : Scale can only be used with numeric inputs”.

Now it´s working fine and I won´t need my additional “dimensionless” items any more. Thank you very much for leading me to the right direction.

Best regards


ahh, thank you. I’ve set the forecast hours to 120, and am now getting all the forecasts. :slight_smile:

I’m interested in this binding, but is not present in my Paper UI bindings section. I’ve a standard openHab 2.3 installation.

How can I install it ?
