[SOLVED] Openweathermap: forecastDays is to 5 but value in Things is 0

[hariskar (Haris Karachristianidis)]

Platform information: openhabian latest

Hardware: Desktop PC
OS: gentoo linux 64 bit
Java Runtime Environment: zulu latest
openHAB version: 2.5.0-1

Although I have forecastDays=5 in Configuration/Things/Edit/Local Weather And Forecastopenweathermap.things value of Number of Days is always 0. From where comes this value?

In /var/lib/openhab2/jsondb/org.eclipse.smarthome.core.thing.link.ItemChannelLink.json there is no openweathermap entry.

@hariskar

In /var/lib/openhab2/jsondb/org.eclipse.smarthome.core.thing.link.ItemChannelLink.json there is no openweathermap entry.

Maybe because you created the Thing in things file?

Dose the forecast work as you defined it in your things file?

[rossko57]

Daily forecasts are not available to Free API users.
Hourly forecasts are … up to a couple of days ahead.

OpenWeatherMap daily forecasts with free API using plain OpenHAB rules

In case you want to generate daily forecasts with the data provided by a free OpenWeatherMap account without relying on Jython, here’s what I did. I create a number of proxy items that will contain the computed forecast values. These values are updated whenever a new forecast is provided by OWM or at midnight (to overcome the today → tomorrow case for forecasts). The code below provides the following forecast data per day for up to 3 days in advance: Rain (total daily forecast) Snow (total d…

[H102 (CM6.5 H102)]

If you need or want daily forecast take a look at Darksky.
https://www.openhab.org/addons/bindings/darksky/#dark-sky-binding

Works good but you may wan to filter the logs unless you don’t mind the constant updates shown. BTW you only need to use “local” as a filter for all items if using the docs item examples.

EDIT:
@hariskar here is the tutorial to filter the logging (took a minuet to find) if you decide to use it.

openHAB - Filtering event logs

Simple string filtering on the event log. Useful for filtering out high change items that don’t need constant log visibility. Re-posting this as it’s own thread on the recommendation of other members. I also recommend reading Taming openHAB 2 Logging and Log4j2 Sample Config which this was based on. Log configuration data using openhabian-pi is stored in the following file. Location may vary under other installation methods. /srv/openhab2-userdata/etc/org.ops4j.pax.logging.cfg openHAB using …

You will not have to type in each item as I mentioned above just use the local. If you need help or want to see my setup just let me know. BTW you can filter the logs for any item.

[H102 (CM6.5 H102)]

@hariskar there is also Weather Binding without API Key if you use metric system. I’m in US and did not see units in standard so DarkSky was my choice and so far it’s been good.

[hariskar (Haris Karachristianidis)]

Thank you for all replies!
Yes I have a free account, so that is why I can not even set days to number bigger than 0? It becomes 0 from openweathermap website?
It works without problems for current day. I started adding hours and till now I am at 12 hours. So I have to edit openweathermap.items to add all those hours? It will need much time.

I do not use this binding so not sure.

Give DarkSky a try and see if that works for you. You can set it up in just a few minuets by copying the examples in the docs and change only the secret key and location.

[rossko57]

You don’t have to add them all, only what you are interested in. 24hrs for example.

[hariskar (Haris Karachristianidis)]

I installed Dark sky, it receives data from the same station with openweathermap but I prefer it because it has daily weather and alerts.

Only I get some errors:

Glad you like the binding.

BTW, I placed the weather in a seperate sitemap so this only shows when I look at the weather.

[hariskar (Haris Karachristianidis)]

It works, except:

**Local Weather Station**

localStationId

localStationName

localStationLocation

and some other values that look like undefined in basicui/app

[H102 (CM6.5 H102)]

I just removed that part as I really didn’t want or need the info.

[hariskar (Haris Karachristianidis)]

OK,
localDailyForecastTodayMinApprentTemperature
and
localDailyForecastTodayMaxApprentTemperature

look also undefined, should I remove them too?

[H102 (CM6.5 H102)]

Those are undefined for me as well but I haven’t removed them yet. Was waiting to see if anything would change but looks like I may go ahead and delete them.

[hariskar (Haris Karachristianidis)]

OK, at least I did not mess things up if you have this too!
Thank you!

This line

Number localCurrentUVIndex "Current precipitation probability [%d]" <none> { channel="darksky:weather-and-forecast:api:local:current#uvindex" }

has to be changed to

Number localCurrentUVIndex "Current UV index [%d]" <none> { channel="darksky:weather-and-forecast:api:local:current#uvindex" }

[hariskar (Haris Karachristianidis)]

and in sitemap:

        Text item=localDailyForecastTodayMinApprentTemperature
        Text item=localDailyForecastTodayMaxApprentTemperature

to

        Text item=localDailyForecastTodayMinApparentTemperature
        Text item=localDailyForecastTodayMaxApparentTemperature

Should I edit the page https://www.openhab.org/addons/bindings/darksky/ to correct these?

So only

        Text item=localStationId
        Text item=localStationName
        Mapview item=localStationLocation

are undefined. Any idea how we could fix that?

[H102 (CM6.5 H102)]

Nice catch on the spelling.

Yes, it’s allway’s good to have the correct info in docs.
