Australian Bureau of Meteorology integration with OpenHAB

Hi Nick,

I have fixed this. Your weather station does not have atmospheric pressure data and the code was not handling the exception correctly. Also there seems to be very limited forecast data for the area you chose. I will confirm this comparing with BOM site later today.

Please uninstall and then reinstall. You might have to remove and re-add your thing, and possibly restart.

Regards,
Tom

Hi Nick,

I think you want to use ftp://ftp.bom.gov.au/anon/gen/fwo/IDN11060.xml for the forecast instead. You will get 8 days of forecasts but there is one slight problem I see. You will not get the forecast texts as they are in IDN10064. I will have to work out how the XML is referenced.

Regards,
Tom

Ahh I see, when I saw the limited data, I assumed it derived it from the parent-aac but looking at the normal bom website, at the bottom is says : Product derived from IDN11060 and IDN10064

tomitan · February 14, 2019, 3:13pm

Good observation. Looks like you do actually need both for a complete forecast. I have modified the code to derive from both.

If you reinstall the binding now you will notice the configuration screen has changed. You will need to enter both precis forecast product ID and city/town forecast product ID.

See screenshot below for what you need to enter for Terrey Hills.

NicGray · February 14, 2019, 8:46pm

Thanks! Looks good, will let you know if anything else crops up. Pity you cannot easily see the Area ID on the BOM website as you can pull the other values from it and saves jumping into the various xml. I assume they must have some table that links your area to the closest station (and all it’s various ID’s and files)?

Really great work on this @tomitan. Thank you for your efforts

The binding works quite well and I look forward to creating a nice habpanel for the data.

I did want to bring to your attention a number of WARNings I experienced in the logs (a snippet is below):

11:41:09.077 [WARN ] [e.core.thing.binding.BaseThingHandler] - Handler BomHandler of thing bom:weather:884f09fe tried updating channel day1#dewPoint although the handler was already disposed.

11:41:09.089 [WARN ] [e.core.thing.binding.BaseThingHandler] - Handler BomHandler tried updating the thing status although the handler was already disposed.

This did not occur initially and only occurred after I had started to add items (by text file). A search of the forums produced the link below. I admit I did disable/enable the binding several times within a few minutes via Paper UI which may have caused the issue.
https://community.openhab.org/t/handler-disposed/49168/13

Not sure if that helps any.

Just wanted to say thanks again for taking the time to produce something like this. It is really appreciated.

NicGray · February 15, 2019, 4:19am

Probably worth pasting your item file contents…

tomitan · February 15, 2019, 9:28am

Yes they would have some mapping tables/files. Probably not available to the public. I couldn’t find anything in the product catalog but if you do find something let me know.

tomitan · February 15, 2019, 9:31am

You’re welcome. I’ll do some investigation on that issue.

tomitan · February 17, 2019, 8:22am

Hi Lucas,

I noticed this during re-installation of the binding. But after a couple of instances the issue went away.

In any case, I have read the thread you pasted and modified the code according to the people’s recommendation as a precaution. The side-effect of this is that now it takes a little bit longer for the binding to be “online” initially.

Let me know if you still get the error in the log.

Anquietas86 · February 18, 2019, 4:59am

This is my closest station.
I’m guessing the two IDs at the top of the page are the weather station ID & the observation product ID?
How would I work out the other IDs to use?

NicGray · February 18, 2019, 6:50am

See the readme here: https://github.com/tomitan100/org.openhab.binding.bom

tomitan · February 18, 2019, 8:03am

Hi Josh,

Not quite. So based on my instruction here you want:

Observation product ID = IDS60920
Weather station ID = 94683
Precis forecast product ID = IDS10044
City/town forecast product ID = IDS11041
Area ID = SA_PT028

The forecast data for your area (Kuitpo) is a bit tricky to find. It actually falls under “District Forecast” products, which was not documented in my instruction. You are near Mt Barker/Mt Lofty Ranges, so I chose that as the area ID. If this is incorrect please find the correct one.

Let me know if you have any issue.

Gusl79 · February 22, 2019, 11:30pm

Hi Tom,
Thanks for your work on this, I’m in Adelaide.
I’ve tried to install the binding but the thing doesn’t seem to come online.

Screen shot of my parameters below;

The following was in my log file;

tomitan · February 23, 2019, 6:10am

Hi Gus,

I tried your config and it’s working fine for me. What version of openHAB are you using?

tomitan · February 23, 2019, 6:45am

Hi CL,

You should probably read openHAB documentation on how to configure openHAB. But to get you started, once you have added the BOM binding in PaperUI:

Go to Configuration -> Things -> BOM.
Click on the blue round checkbox next to Air Temperature under Today’s Forecast.
A popup should appear. Under Please select the item to link, choose Create new item.
Leave everything as default. Note the ID of the field under Name (BOM_Day1_AirTemperature).
Click Link.
You can repeat the above steps if you want to show other fields.
Go to Control panel.
You should now see the field you added under BOM panel. The value may take a while to update.
Now go to HABPANEL UI. This is available on the main index page.
Hit the cogwheel on the top right to edit panel.
Add new dashboard.
Type a name for the panel.
Click on newly created panel.
Click on Add Widget and select Dummy.
Click on New Widget options (three vertical dots) and select Edit.
Next to openHAB Item, find BOM_Day1_AirTemperature.
Click Save in the modal.
Hit Save then Run on the top left and you be able to see the temperature displayed. If not, hit refresh on your browser.

That’s the basics. If you want to use custom template similar to the one I use, please check out Matrix Theme for HABPanel. If you are interested in a template I created let me know and I will attach here once I am done. It is still work in progress.

I have attached the full items mapping if you prefer to use instead of manually creating and linking each channel. You will need to name your BOM Thing ID as “default” to use.

Gusl79 · February 24, 2019, 11:22am

Perfect thanks Tom…I updated my openHAB and now it’s working! Thanks a lot for the reply and the BOM binding.
Cheers Gus

@tomitan Awesome job on the binding, thanks. light_smile:

Not sure if anyone else is seeing this but the Max Temp seems to change dramatically as the files are being processed:

tomitan · March 3, 2019, 1:44am

Yep, I see this myself in the morning. Then it settles down afterwards. Looks like it affects only “Day1” (today). I’ll get to the bottom of it.

tomitan · March 3, 2019, 5:24am

Hi Andrew,

Should be fixed now if you reinstall the binding. The code was updating min and max temperatures from observation XML for Day1, which is incorrect as those are not forecast temperatures but historical temperatures.

Regards,
Tom
