Keep us posted. That's been offline for quite some time.

Weather Website PHP/AJAX scripting / TweetWX Script Issues
« Last post by Gonzo1982 on Today at 11:31:39 AM »
So instead of using cron to run the script (Bluehost made it to complicated and I don't want to upgrade to a VPS), I'm using a wscript on my windows computer to execute a powershell script (so that its silent, no powershell window) and using task scheduler to execute the script during the schedule I specified.

Here is that script for those interested:

Save As tweetforecast.ps1

Code: [Select]
Invoke-WebRequest http://websiteaddress/TweetWX/TweetWX-forecast.php
Save As forecast.js:

Code: [Select]
var wshShell = new ActiveXObject("WScript.Shell");
wshShell.Run('%SystemRoot%\\system32\\WindowsPowerShell\\v1.0\\powershell.exe -ExecutionPolicy Bypass -File "C:\\Scripts\\tweetforecast.ps1"', 0, false);

Now create a task in task scheduler that executes wscript and put the location of the forecast.js file in the argument section.

Anyways back to my issue:

I got this error this morning and I suspect it is because the forecast hasn't been updated, but I'd like it to go ahead and post anyways, any way to do that?

Davis Instruments Weather Stations / Re: DIY "GREEN DOT" Data Logger

Like I said, I'm not a programmer.  But if you'd combine a copy of weewx or Cumulus MX on the same machine, you'd have a potent little device.  And you'd run it a lot cheaper than a second console and logger.  But you'd still need a barometer connected to it as well as probably an inside temp if you truly are replacing the console.

Assuming that you already have the Pi and an SDR dongle, you can get and use an Ambient Temp/humidity sensor (which can be located where you want it, rather than being constrained by the location of the Pi, with its power supply) for just over $10.00, and a decent barometer sensor to wire to the Pi for about the same amount. Some programming would be required, of course.  :-)

I'm looking for a wireless anemometer transmitter for the old vantage pro (not 2).

My idea was to basically create a replacement for the Virtual VP program.  Have a PI receive the data via SDR.  Then have a small database running on the PI.  Have it dish out the live data just like Virtual VP did.  Ideally via IP and multiple ports, and possible a serial driver.

Then have the data base store a history, basically like the data logger.  But also keep a history of when the last communication a particular port handed out the data.  Have a couple of weeks worth of data similar to what VVP could have done.

Weather Website PHP/AJAX scripting / Re: Voice Enabled METAR Reports

Interesting. It has a natural sounding voice.

A possible alternative to this might be an Air Band receiver set to receive the local airport AWOS. I can receive my local station KPZQ on WX AWOS-3: 118.125 MHz.

Something like the Weather Radio project could be used to port the audio. My local station updates every minute. My Ham 2 meter receiver can pick up the aircraft VHF range on AM quite well since I am less than a mile away.

I have a Davis VP2 (with Aerocone for the summer, old cone & heater for the winter). I also have a NovaLynx 8" TBR and a CoCoRaHS gauge. When winds are light and rain is straight down, I have had close agreement between all three (+/- 0.01). When winds are significant they can vary by several hundredths of an inch.

I have calibrated the NovaLynx with their calibrator and checked the Davis against the calibrator as well.

I have a small back yard which violates the placement guidelines for rain gauges.

Having said this, I agree with others that the pre-Aerocone Davis seems to have a propensity for under counting, not over counting when wind is present.

It might be worthwhile inspecting the reed switch and connector in the ISS SIM. Also a frayed and intermittent cable could cause problems if the exposed rain switch wires are contacting each other.

If you had a consistent proportional error observed across a wide range of wind conditions and rain rates you would have a suitable situation for adjustment by calibration. Otherwise you are quite likely in calibrating to tune for agreement in one particular condition which may not be the best overall for your future experience.
