Announcing OpenWeatherMap binding for Eclipse SmartHome / openHAB

michaeljoos · December 26, 2018, 10:21am

@ngalfas I’m trying this as well and struggling with the icons. “weather-underground-icons” does not work anymore as you get now a number for the condition-id. And the icon that you get out of the image-channel is too small for HabPanel-Integration.

kugelsicha · December 26, 2018, 11:56am

I do it with a MAP transformation…

f.e.: (you need to install the map transformation service in PaperUI
create openweathermap.map in folder openhab2-conf/transform

601=snow
OWM_WEATHER_CONDITION_ID_NUMBER=YOUR_IMAGE

and in your .items file you have something like this:

String owmCurrentConditionId "Current Condition ID [MAP(openweathermap.map):%s]"

EDIT:
Or another way to do it…

Hey there,

I need some help figuring out things with this binding - first off, I like this one very much, especially since Wunderground and Yahoo will stop their free API services soon.

I have a working API key for the free plan. I have figured out that I have to add the weather-and-forecast thing using

forecastHours=96, forecastDays=0

(the forecastHours something below 5*12 for the free plan and forecastDays set to zero because otherwise, I end up with @text/offline.conf-error-invalid-apikey errors.

What I am really missing is a hint on how to use forecast data beyond 24 hours. If I try to add items using a channel like openweathermap:weather-and-forecast:api:local:forecastHours48#time-stamp (extrapolating the working items for Hours12 or Hours24), I get nothing (in PaperUI, those don’t even show up in the “Local Weather and Forecast” item list on the “Control” page). In PaperUI, I see items like openweathermap:weather-and-forecast:api:local:forecastTomorrow#time-stamp advertised on the things-page of of the forecast thing, which result in having NULL/NaN data.

Are there any working examples using the free plan with forecast data for 3-5 days?

kugelsicha · December 27, 2018, 10:33pm

Hi, this is what i use in my items file…

// Forecast Hour48
Image					owmForecastHour48Icon			"2 Tage Vorhersage Wetterlage Icon"					    {channel="openweathermap:weather-and-forecast:api:local:forecastHours48#icon"}

Number:Dimensionless	owmForecastHour48Cloudiness		"2 Tage Vorhersage Bewölkung [%.1f %unit%]"			    {channel="openweathermap:weather-and-forecast:api:local:forecastHours48#cloudiness"}
Number:Length			owmForecastHour48Rain			"2 Tage Vorhersage Regen [%.1f %unit%]"				    {channel="openweathermap:weather-and-forecast:api:local:forecastHours48#rain"}
Number:Length			owmForecastHour48Snow			"2 Tage Vorhersage Schneefall [%.1f %unit%]"		    {channel="openweathermap:weather-and-forecast:api:local:forecastHours48#snow"}
DateTime    owmForecastHour48Timestamp	"2 Tage Vorhersage Zeit [%1$tA, %1$td.%1$tm.%1$tY %1$tH:%1$tM]"			{channel="openweathermap:weather-and-forecast:api:local:forecastHours48#time-stamp"}

sometimes you have to wait a couple of minutes to get the first data… but works perfectly here…

hope this helps

I have the same problem as @JoeSey

I installed the binding in OH 2.4 stable, using free openweathermap account.

Things file:

Bridge openweathermap:weather-api:api "OpenWeatherMap Account" [apikey="my_api_key", refreshInterval=10, language="nl"] {
    Thing weather-and-forecast local "Local Weather And Forecast" [location="xxxxx,yyyyy", forecastHours=72, forecastDays=0]
}

In PaperUI, I see forecast channels 3hrs, 6hrs etc. But no channel beyond 24h.

To confirm that this is not related to PaperUI, I looked via the REST api:
http://openhabianpi:8080/rest/things/openweathermap:weather-and-forecast:api:local. I found channels like

openweathermap:weather-and-forecast:api:local:forecastHours24

, but for example no channels with “forecastHours27”, “forecastHours30” etc.

During my experimentation yesterday I believe I saw the channels momentarily, but then they seem to have disappeared after I made an edit to the .things file. Unfortunately I didn’t keep track of my changes. Now I waited about 24hrs to see if they would pop up, but they didn’t.

Any ideas?

hansvandamme · January 5, 2019, 10:43am

OK, I solved it by restarting the binding via Karaf:

First I activated debug logging:

openhab> log:set DEBUG org.eclipse.smarthome.binding.openweathermap

Then I found the bundle number and restarted the binding:

youropenhab> bundle:list
<SNIP>
242 │ Active   │  80 │ 0.10.0.oh240           │ Eclipse SmartHome OpenWeatherMap Binding
openhab> bundle:restart 242

Logging shows that channels and channel groups are created

The binding itself works fine for me on 2.4.0, the log however shows the following errors after a restart. Always for 27#time-stamp, the data is coming fine.

Unfortunately the quality of data in the free hourly forecast is at least for my location (Bratislava, Slovakia) miserable. I tried to write a rule collecting min and max temperature of the following three days, got weird numbers and started to investigate. I checked on their webpage and the data is inconsistent there as well - e.g. for tomorrow the daily forecast shows -6.1 °C max, -6.7 °C min, the hourly data however contain -3.1 / -10.3. Huh. Two usually reliable sources show -2/-4 and -1/-5, let’s see what the reality is but I highly doubt the -10.

Noam_Shaharabani · January 6, 2019, 10:27pm

I’m getting an error when trying to install this binding

[ERROR] [core.karaf.internal.FeatureInstaller] - Failed installing 'openhab-

vzorglub · January 7, 2019, 12:14am

The duplicate channel bug is fixed in the snapshots

cweitkamp · January 7, 2019, 10:59am

Hi Noam,

How did you try to install the binding? Which OH2 version do you use?

jsable · January 7, 2019, 7:10pm

Anyone know how to convert the temperature to Fahrenheit? I tried adding units=“imperial” at the end of the thing configuration, but does not seem to help:

Thing weather-and-forecast local "Local Weather And Forecast" [location="42.99, -71.14", forecastHours=0, forecastDays=7, units="imperial" ]

I’ve searched on the OpenWeather site and it reads to get fahrenheit, add units=imperial to the API call, but I am not sure where to add this. I figured on the Thing configuration would be the place, but alas, no. It also did not work not having imperial in quotes.

Thanks,

~John

Noam_Shaharabani · January 7, 2019, 11:25pm

i’M USING OPENHAB 2.4

installed from the paper ui addon

butteryak · January 8, 2019, 6:37am

I have the same question. Not sure how to convert to Fahrenheit.

dominikkv · January 8, 2019, 7:08am

OpenHAB can do it for you. Just use Fahrenheit in your label. Have a look at https://www.openhab.org/docs/concepts/units-of-measurement.html#numberitem-linked-to-quantitytype-channel

jsable · January 8, 2019, 11:57am

Thanks Dominik (@dominikkv), that resolved my issue!

~John

ads · January 14, 2019, 3:07am

Speaking of API - the openHAB API, not the OWM API:
If I want to add a new location using the API, is there an easy way where I just provide the basic details from the Model Schema for POST /things, or do I have to fill in all the channels manually?
I’m hoping to avoid doing that, because that needs to be updated every time the channel list is changed or updated.

rossko57 · January 14, 2019, 11:58am

Can that be rephrased as - set up a forecast Thing with all its channels & Items, then later adjust the location of that predefined forecast Thing via REST ?

Thing weather-and-forecast mysterylocation "Local Weather And Forecast" [location=

ads · January 14, 2019, 12:08pm

If it’s just a single, simple API call, yes, that might work. Right now I don’t see a way to avoid manual channel creation, but I might be missing something. Hence my question.
