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

@Area-49

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. :-)

Thanks again for your effort on putting this together!

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

Mykle1

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?

Mykle1

Now I’ll add the most recent observation time to MMM-WISP for those that may want the rotating, bottom_bar version.

Done!

The updates have been pushed to Github although there is no documentation as of yet

@Mykle1

Merged both modules into one. Static or Rotating by config option

I’m planning on pulling this down at some point soon… just having some stability issues with my raspberry pi at the moment. It keeps crashing on me every 12-24 hours…

That sux. Are you getting any errors? It just freezes?

My Pi mirror has crashed only twice in 11 months and it was due to losing wifi (internet) from my provider. Even after wifi (internet) was restored the Pi still needed to be rebooted. Other than that, it has been rock solid.

I mention this because it might not be immediately apparent if the same thing were happening to you

@Mykle1 I don’t know what’s going on with it, I’m not Linuxy enough to work out how to find the problem. It’s basically ok for a day and then I come down stairs in the morning and it’s unresponsive, no ping, ssh, anything on the screen so I have to pull the power.

I’m wondering if I’ve got it doing too much, it’s got MM, Alexa and Face recognition all going on. I’m also slightly suspect about the power supply to it being part of the issue.

If you have any hints of where I could start, please let me know… I don’t fancy rebuilding it from scratch… :(

Well, 2.0 amps minimum on the power supply although I think 2.5 is optimum.

Hints? Well, suggestion.

Disable all but the default modules and run that for a day and see what happens. If all is well then introduce one at a time and test again. See how that goes for starters

@mkyle1 - Great job on the module, it looks superb. I’ll be adding it to my mirror very soon.

I understand you’re working on this on your own time, just a couple of config options for you if you’re in the mood to do anything more with the module ;-)

Most of Eur runs on KM for the viz. I wouldn’t have a clue what a Statue Mile looks like out of the window!
Typically winds reported at xxx degrees at yy kts and shorthand would be 260/05 rather than @.

I would be happy enough to change this on my mirror but a config option would be (far) too advanced for me to try and implement!

@stephenmelody - Ref the crashing:
First thing I’d do is check the power supply, RPi are really picky!
Check out the command ‘dmesg’ - very insightful for tracking down issues as it is timestamped. This will clear on reboot so it’d need to be checked before the crash.

If this is fruitless,

/var/log/messages
/var/log/syslog
/var/log/kern.log

Cheers lads,

Johnny

Thanks, I appreciate that. I did it as a request from a user so forgive my lack of aviation understanding.

That’s easy enough to fix. I’ll take care of that. Maybe even as soon as tonight.

As far as the Statute Mile/KM situation is concerned. The API only provides Statute Mile (SM) in the data. I didn’t do any conversions because I was going to move to another API that provided both, making it easier to give you a config option and a whole lot less coding for me. However, I will look at it again and see what it involves. Worst case scenario you’d have to wait for my moving to the other API but I can’t tell you when that would be. :-)

@XT16Johnny

Just in case others want the @ symbol as a separator between wind speed and direction I made it a config option.

sym: "@",  // or sym: "/",

Result:

So, for those interested, you can do a git pull in the MMM-PilotWX directory to update or download and install as usual.
