@jkandasa I thought I was wrong, perhaps you stopped reading at some point, but I had to go back and read some more, and I will do a short summary here to save your time from reading it all over again.

From all indications the Wundergroung community are a little bit disturbed by IBM who took over the crowd sourcing data service and now run it solely as a Business. The new management has given notice to stop serving free data and are now at a crossroads with their personal weather station PWS owners who upload these small packets of data to them for free (and have been doing so for over many many years.). The new management has committed to allow these PWS data suppliers to continue to enjoy free and easy access to their own data, but not the entire crowd sourced data - They have created an alternate purpose built service for this, albeit, at a small fee - $200/month.

From my own perspective, the service is closed for good to people like us, thinkerers and hobbyist who only want to read a tiny snippet of that record. As non-commercial users (including educationist) one would expect the WU to leave a window open, but their deadline will be in a few more days, and at this time, they have not yet provided any other access that is cheap enough for poor ppl like me, so I will say this door is shut for real.
In summary, below are the two comments that capture the essence of the ongoing fight. I wont hold my breath on this one, i am looking for an alternative.

Sorry @jkandasa, I have been on the move travelled for the Christmas Holiday. so I am away from my nodes and sensors. But I have the MYC on my laptop. so here are the data you requested for.

and the Variables -

What am I doing wrong? I am posting the Nodes and Sensors just incase...

Hello @jkandasa
I have been out of town, haven't touched MYC for a while. Just popped intoday and tried my hands on the script. Ran it after creating the Operation and the Timmer to trigger and run it. But it wont tun. I get an error ```

{
  "errorMessage": "TypeError: Cannot get property \"status\" of null in <eval> at line number 8"
}

Here is the JS script that I edited for 8 valves

var myImports = new JavaImporter(java.io, java.lang, java.util);

with(myImports) {
  
  var LoopThroughValves = mcApi.variable().get("Status");

  //Check already running?
  if(LoopThroughValves.status !== 'running'){

    //Update as running
    valveStatus.value = "running";
    mcApi.variable().update(valveStatus);
    mcApi.logger().debug("Loop Through Valve Script Triggered...");

@skywatch @jkandasa

This sounds like the solution to my weather issues. I was looking at OpenWeather and Yahoo until someone mentioned MetCheck... So @skywatch can you please tell me the procedure to pull weather information for MyC via metcheck. Is it free? Do I need to obtain a Key? Where do I append the endpoint in MyC? Can you show me a screengrab of your setup? Thanks in advance.

@skywatch so how do I create an end point to use this in MyController?

@skywatch Please can you create a link to the free weather service you are refereeing to. Metcheck. Thanks

I have created the UID Tags... See below, did I do it right?

I then tried to create the JS script as described in your old reference you supplied... but I got an error.

What are I doing wrong?

Thanks @jkandasa you are awesome support. I see the requestTime() function call in the sketch, but where in MyController do I add the node code?

void receiveTime(unsigned long _timestamp){
   // do actions with received time
}

Hello @njbuch I have just completed a MySensors Project for an 8 valve water sprinkler system, it requires Wunderground App to run, however, I just noticed that as at today, the service no longer exists for free. So I have opted for another alternative, Open Weather Services. I have obtained a key.

Do you think I have set it up right? Do you have other/better alternatives from open weather data that are MyController friendly? See a screen shot of my setup.
