OpenWeatherMap Extension - Support for UV Index API

cweitkamp · January 14, 2019, 12:31pm

Hi Paul,

Unfortunately I will not have time to work on the OWM binding this week. Maybe on the weekend. I am preparing for an examination.

Keep you posted.

Best, Christoph

After upgrade to OH 2.5.0.M1, i extended my “owm.things” with the uvindex-thing.

Bridge openweathermap:weather-api:api "OpenWeatherMap Account" [apikey="my-Key-1-32", refreshInterval=30, language="de"] {
     Thing weather-and-forecast local "Local Weather And Forecast" [location="xx.xxxxxx,y.yyyyyyy,zz", forecastHours=120, forecastDays=0]
     Thing uvindex local "Local UV Index" [location="xx.xxxxxx,y.yyyyyyy", forecastDays=7]
}

and added this two Items

DateTime             localCurrentUVIndexTimestamp            "Timestamp of last measurement [%1$tY-%1$tm-%1$td]"           <time>         (gOWM,gOWMOutlook)  { channel="openweathermap:uvindex:api:local:current#time-stamp" }
Number               localCurrentUVIndex                     "Current UV Index [%d]"                                       <uv_index>     (gOWM,gOWMOutlook)  { channel="openweathermap:uvindex:api:local:current#uvindex" }

to my .items File.

After Restart i found this warning message

2019-01-25 17:41:42.512 [WARN ] [mon.registry.AbstractManagedProvider] - Could not update element with key openweathermap:uvindex:api:local in ManagedThingProvider, because it does not exists.

in my logger.

So i started the system again in Debugging_mode for the Binding, i found this messages too.

Don’t see the bug in the setup. Even i get back a value from the channels. Does anyone see ?

cweitkamp · January 27, 2019, 7:53pm

Hi Peter,

You can ignore the warning. The binding will deliver the data for uvindex reliably with or without it. It is completely harmless.

fibu-freak · January 27, 2019, 8:24pm

Hi Christoph,

it’s ok thx.
I saw this warning in the past, i think it was the old weather-binding. But with the check of you and your ok it’s even better.
EDIT:
But just saw, that

Number:Speed         localCurrentGustSpeed                   "Current Gust Speed/Windböen[%.1f %unit%]"                    <wind>         (gOWM,gOWMOutlook)  { channel="openweathermap:weather-and-forecast:api:local:current#gust-speed" }

gives no value back.

cweitkamp · January 27, 2019, 8:46pm

I am afraid that is true in over 95% of the locations. It depends on the capabilities of the weather station reporting the data for your area.

fibu-freak · January 27, 2019, 8:59pm

Hi Christoph,
no problem, i can live with. Just a last question.
When looking in the JSON-String

{

    "cod": "200",
    "message": 0.0037,
    "cnt": 40,
    "list": [
        {
            "dt": 1548622800,
            "main": {
                "temp": 2.14,
                "temp_min": 1.11,
                "temp_max": 2.14,
                "pressure": 941.25,
                "sea_level": 1006.28,
                "grnd_level": 941.25,
                "humidity": 95,
                "temp_kf": 1.04
            },
            "weather": [
                {
                    "id": 500,
                    "main": "Rain",
                    "description": "Leichter Regen",
                    "icon": "10n"
                }
            ],

i saw the Expression"“temp_kf”. Is this a Channel in the Thing. Or is this perhaps “Temperature felt” and could be a Channel in the future ?

Thx in advance for short reply

Cheers Peter

cweitkamp · January 27, 2019, 9:06pm

Good question. It is listed as

list.main.temp_kf Internal parameter

in their documentation. No further explanation.

fibu-freak · January 27, 2019, 9:13pm

so if it’s “internal parameter”, it’s not for us

ThomasOH · February 4, 2019, 9:39pm

Thanks for creating the extension. I installed it and got it working, including the new UV data. FYI, the uvindex example has a typo. Specifically, the time-stamp channel ID is shown as timestamp.

I’m a new OWM user. Some basic questions about the binding:

I manually installed the 11.0 snapshot (Dec-26-2018) binding on Openhab2 using the linked file from this announcement post. But I’ve read that OpenWeatherMap can be found on the Eclipse IoT Market. But I cannot find it on the IoT market web repository site and it is also missing from my OpenHab-2.4 addons listing. Is there an alternate place to find the latest update?
I see a persistent warning in my Openhab2 logs that I cannot solve, as follows:
Could not update element with key openweathermap:uvindex:api:local in ManagedThingProvider, because it does not exists. Everything works fine, but I would appreciate any advice on how to solve that warning.

Hi Thomas,

Thank you very much for your feedback.

Nice catch. I will fix it.

wrt 1. The binding was available on the Eclipse Marketplace before my initial contribution has been merged. I deleted it over there because I do not see any reason to maintain several version in different locations.

wrt 2. See my comment above.

ThomasOH · February 5, 2019, 11:12pm

@cweitkamp, Thanks for the info. I will ignore OpenHab’s log warning message. Would be great if someone found a way to prevent it.

Do you have an official repository for future updates to the OpenWeatherMap extension? It would be nice to be able to visit a dedicated place and check for updates.

BTW, I just read that the eclipse smarthome community site has an uncertain future. I’m not sure what it means to developers like you that share code there. Hopefully there’s a happy ending.

No worries. openHAB will continue without restrictions. We decided to move the ESH code into openHAB Core and all ESH add-ons to openHAB 2 Add-ons.

If you like to follow what is going on I would suggest to subscribe to this topic.

The official repository for the binding is openHAB 2 Add-ons.

ThomasOH · February 7, 2019, 4:07pm

@cweitkamp, I appreciate the link. Subscribed.

Blockquote
The official repository for the binding is …

I had previously seen OWM’s source code at the OH github add-ons area. But the compiled jar is not found there, so that is why I asked about an official place to download the latest release (compiled). However, from reading the details in the link you provided it sounds like that will be taken care of when the ESH code is fully migrated over to the OH core.

Thank you again for creating the OWM binding!

cweitkamp · February 7, 2019, 4:25pm

Thanks. I little bit faster than me It is also possible to switch your OH 2 version to snapshot build.

ThomasOH · February 7, 2019, 9:33pm

Nice. I bookmarked the Jenkins OWM url, so I’m good to go.

Thomas

Brignoud · February 28, 2019, 1:37pm

Please, can you explain me why you create a item this way?
It seems it doesn’t really match with the reference in the sitemap counterpart definition (Text item=localCurrentTemperature) and and the value never shows in fact.
But removing :Number or referencing it instead of “localCurrentTemperature” for example make the expected result to come out

Searching for the Item reference documention I didn’t discovered anything about the semi colon assignement but the Group type only

idkpmiller · March 1, 2019, 2:08am

I am assuming the question is aimed at @cweitkamp and just quoting me?

Thanks
Paul

Brignoud · March 1, 2019, 10:44am

Onestly I was referring to the informations example you quote inside your replay (6/7 jan)
Isn’t it?

fibu-freak · March 1, 2019, 11:04am

Defining your items in this way, means to use UoM-System see here and here.It should work quite fine if your setup is ok. I’m using it in the same way.

.items

Number:Temperature   localCurrentTemperature                 "Current temperature [%.1f %unit%]"                           <temperature>  (gOWM,gOWMOutlook)  { channel="openweathermap:weather-and-forecast:api:local:current#temperature" }
String               localCurrentCondition                   "Current condition/Wetterlage[%s]"                            <sun_clouds>   (gOWM,gOWMOutlook)  { channel="openweathermap:weather-and-forecast:api:local:current#condition" }
Number:Pressure      localCurrentPressure                    "Current barometric pressure/Luftdruck [%.1f %unit%]"         <pressure>     (gOWM,gOWMOutlook)  { channel="openweathermap:weather-and-forecast:api:local:current#pressure" }
Number:Dimensionless localCurrentHumidity                    "Current atmospheric humidity/Luftfeuchtigkeit [%d %unit%]"   <humidity>     (gOWM,gOWMOutlook)  { channel="openweathermap:weather-and-forecast:api:local:current#humidity" }

.sitemap

    Text item=localCurrentTemperature
