MMM-aviationwx (Aviation weather)

Area 49

Thanks for your work on this!

I just installed Magic Mirror and started looking around for an aviation weather module that included Alaska. I just now stumbled on this thread, and see that your work should include the airports that I want in my list. I’ll install and test it as soon as I get a chance.

Great! Let me know how things go. Use the four letter ICAO for each station you want to see

@Mykle1,

Looks like there is a dependency required - from my PM2 error log file: Error: Cannot find module ‘xml2js’

I’m just getting started figuring out Linux, Git repository, and Javascript, so I’m not sure where to find - and under what directory to install this dependency.

Is this the one to install? https://github.com/Leonidas-from-XIV/node-xml2js

Thanks

You have to run npm install in the MagicMirror/modules/MMM-(THE MODULE NAME) folder

I don’t know which one of the two you are trying

So for MMM-Pilot it’s

npm install in the MagicMirror/modules/MMM-Pilot directory

And for MMM-WISP it’s

npm install in the MagicMirror/modules/MMM-WISP directory

Sorry about the lack of directions. I only just put this up for testing so it hasn’t been officially released or properly documented.

Mykle1,

Got it to install & run. Thanks for the clarification on how to install.

I put in my chosen airports in AK (also one in HI - just so I can feel bad about how cold it is here right now!)

Not sure if you know, but you can return only the most recent Metar data from each airport by using a slightly different URL and the following format:
http://aviationweather.ncep.noaa.gov/adds/dataserver_current/httpparam?dataSource=metars&requestType=retrieve&format=xml&hoursBeforeNow=4&mostRecent=true&stationString=PALH

I like the output format. I think it works well for at-a-glance information purposes. However if I had a choice, I’d like a config option for temperature and dew point units. I’m used to looking at these in Fahrenheit. I have my own simple personal website where I link to a few Metar reports directly, and the pages show both the raw units and (converted).
Example for PALH (Lake Hood AK): http://www.aviationweather.gov/adds/metars/?station_ids=palh&std_trans=translated&chk_metars=on&hoursStr=most+recent+only&submitmet=Submit

Not a huge deal on the units, but maybe put it on the wishlist?

Thanks again for your effort on putting this together!

Sure, I’ll keep that in mind. I’m not in a rush after 500+ lines of code already. :-)

You’re welcome. It’s nice to be appreciated. :-)

Now, the first url you posted is great. If you can edit it to pull multiple ICAO’s at once, then I’ll use it. I tried briefly. It only seems to return 1 ICAO. The url I’m using pulls observations from the last hour.

The second url you posted is also great. However, it doesn’t get me to the xml data that I need for the module. If you can manage to get a url to return the very same data like this, we’ll be jamming

I feel obliged to state that this module should only be used for entertainment purposes. Yes, the data is being pulled from the very same sites that you use ordinarily, but the thought of any of you relying on this module’s data for actual flights scares the shit out of me. Not that you would. You’re pilots. You’re smarter than that, I hope. :-)

How would that work anyway? You’re going to hang your mirror in the cockpit? :-)

That’ll be a $10.00 fee for Wi-Fi. :-)

Peace!

When did 3.3k people look at this topic? Crazy

Ok, so I’ve done the best I could with alignment of columns, considering there ARE no columns. At least the Flight Rules icon, the station, the wind direction and speed are relatively straight. I’m pretty much done with that. I hope it will suffice.

I’ve added a Station header and a Conditions header. Here they are underlined. They don’t have to be. I was just experimenting.

I’ve also added the most recent observation time to the end of each station’s conditions. This is converted from Zulu time to your local military time. Is this the way it should be?
