WeatherCompany binding (WeatherUnderground replacement for PWS data uploaders only!)

peterghome · July 18, 2020, 6:32am

Hi Mark,
I installed the weather company Observations and I works together with my weather station at home. My problem is the unit. Wunderground sent the values in Fahrenheit.
My log:
2020-07-18 08:12:52.683 [vent.ItemStateChangedEvent] - Temperatur_Outside changed from 57.0 to 62.6
My item:
Number Temperatur_Outside "Aussentemperatur [%.1f C]" <temperature> (EG_Wohnzimmer) [ "CurrentTemperature" ] {channel='weathercompany:weather-observations:ff55d7d5:currentTemperature'}

I want the value in Celsius. Do you have a solution?
Found the mistake:" Number:Temperatur" instead of "Number!

Yep. That’s it!

Just dropping this here for anyone interested to use as a base for their own tinkering, or improving via pull requests. Hope it’s useful to someone besides myself.

Very nice!

Thanks @watou

Looks great!

Hi Mark,
I installed the weather company binding. In the thing Weather Company Forecast all Items …Wind Speed show an incorrect value (today 1.0 km/h).
The correct value according to the website is higher (around 4.0 km/h today).
Do you have a solution?
Many thanks,
Gisela

mhilbush · October 30, 2020, 10:26pm

You’ve not provided much information to help me understand the issue, let alone find the solution. The binding displays the information it receives from the Weather Company API. I have no idea what web site you’re referring to.

rose78 · October 31, 2020, 8:03am

In the Paper UI the value for the item “wind speed” shows 1 km/h:

But the correct value i my Weather Company API is more than 1 km/h:

Why is the value in the item “wind speed” wrong? All other items show the correct values from the API.

mhilbush · October 31, 2020, 2:44pm

I’m not sure why you keep saying it’s wrong. If you put the binding in debug mode, you’ll be able to see what’s being returned by the Weather Company API. If the binding is showing something different than that, then please post the debug log, the item definition, and the value of the item from the karaf console or event log. You’ll want to look at the Wind Speed values from the Day0 (today) day and night dayparts.

Note that the value returned from the WC API might be in Imperial units, so you may need to convert the units.

Assuming they match, I have a couple of other thoughts:

It looks like you’re showing a screen snip from the Weather Underground web site. I’m not certain that the API and the Weather Underground UI are guaranteed to match.
Also, you appear to be looking at the Weather Underground hourly forecast, versus the Weather Company API, which is a twice a day forecast. I can’t imagine how those could match other than by pure coincidence.
Lastly, I have no idea what IBM may be doing behind the scenes with these different assets they acquired (Weather Underground, The Weather Company, and potentially others). What I do know is that things took a turn for the worse with Weather Underground following the IBM acquisition.

Configuration of the WindSpeed Items:

Values WindSpeed in de API (https://api.weather.com/v3/wx/forecast/daily/5day?geocode=…):

Please don‘t use screenshots but post your config and logs using code fences.

mhilbush · November 1, 2020, 3:59pm

Thanks for posting the detail. I think I see what’s wrong.

The speed values returned from the API are in meters per second. However, the binding is updating the state using the returned value, but with the units kilometers per hour. I think that explains why the API response is 6 and your item value is 2.

Can you change your item definition from [%.0f %unit%] to [%.3f %unit%]? I expect a wind speed of 6 would result in the item value of 1.667. If so, that that would confirm it.

So, whatever wind speed value is being returned by the API, the item would be that value divided by 3.6.

rose78 · November 1, 2020, 8:17pm

Now the item value is: 2.000 km/h instead of 5 km/h

Log: 2020-11-01 21:15:12.634 [thome.event.ItemStateEvent] - WCF_Day0_Night_WindSpeed updated to 2.000 km/h

API: “windSpeed”:[null,5,6,6,6,5,8,7,7,6,5,5]

mhilbush · November 1, 2020, 9:08pm

Hmm. That’s not what I expected.

Just to be clear, these values are in meters per second.

I built a new version of the binding that properly sets the wind speed units to meters per second instead of kph. Can you uninstall the version you’re running, then put this version in your addons directory?

rose78 · November 1, 2020, 9:23pm

Thank you very much for the quick fix!

mhilbush · November 1, 2020, 9:29pm

Well, I’m not 100% sure that will fix the issue.

Let me know what you’re seeing in the event log. It should be the same as the value you see in the API response, and the units should be meters per second.

rose78 · November 2, 2020, 8:16am

Here the datas from today:

Log:
2020-11-02 09:12:47.352 [DEBUG] [andler.WeatherCompanyForecastHandler] - Parsing daypartsObject: [{“windSpeed”:[2.0,2.0,3.0,2.0,4.0,3.0,3.0,2.0,2.0,1.0,2.0,2.0]}]

API:
{“windSpeed”:[6,5,7,6,8,7,7,6,5,4,4,5]}]}

Items in Paper-UI:
Daytime Weather Forecast for Today
WindSpeed 7.2 km/h

Night-time Weather Forecast for Tonight
WindSpeed 7.2 km/h

I think its not yet fixed.

mhilbush · November 2, 2020, 12:25pm

I need these three bits of information. Thanks.

The Wind Speed item definitions for Day 0 Day and Night
Put the binding in TRACE mode, then post the complete response returned by the API, as well as the URL that the binding executed (please XXXXX out your API key).
The entries from the event log for the Wind Speed item updates.

Also, please post the binding version from the console (i.e. list -s | grep weathercompany)

mhilbush · November 2, 2020, 3:12pm

On my test system, which I just changed from Imperial to Metric, I see the following:

Item definition

Number:Speed WC_Day0_Day_WindSpeed "Wind Speed [%.1f km/h]" <wind> { channel="weathercompany:weather-forecast:myaccount:local:forecastDay0Day#windSpeed" }

Returned from the API (as seen in log with TRACE mode enabled). These values are in meters per second (yes, it’s pretty windy today).

"windSpeed":[10,5,6,0,2,1,3,1,1,0,1,0]

In event log

2020-11-02 10:06:47.738 [INFO ] [marthome.event.ItemStateChangedEvent] - Item 'WC_Day0_Day_WindSpeed' changed from 35.99994240006911596313921474304011 km/h to 36.0 km/h

Conversion factor from m/s to km/h is 3.6, so this looks correct to me.

rose78 · November 2, 2020, 6:53pm

Here the information you need and I can get:

items definition

Number:Speed WCF_Day0_Day_WindSpeed “WindSpeed [%.3f %unit%]” { channel=“weathercompany:weather-forecast:0624b450:forecastDay0Day#windSpeed” }

Number:Speed WCF_Day0_Night_WindSpeed “WindSpeed [%.3f %unit%]” { channel=“weathercompany:weather-forecast:0624b450:forecastDay0Night#windSpeed” }
