Budget Test Station in Aus.
« on: August 09, 2019, 08:17:48 PM »
Hi All,

Just considering getting a second station to experiment with running CumulusMX on a Raspberry Pi.

My Davis VP/2 runs off an old Win8 HP laptop & I've considered putting it on a Pi, but don't want to have it off-line while I'm sorting out setups & testing.

So thought I'd get a second WS to experiment with & maybe repurpose it at a different location later.

Not a lot of specifics to offer, but I peruse it would help if it was a model that used a CP2102 for a virtual com port on it's interface.


Suggestions?

A Davis Vue console and the WiFiLogger may be just the thing for you http://www.wxforum.net/index.php?topic=37610.msg387019#msg387019

Enjoy,
Paul

A Davis Vue console and the WiFiLogger

Probably outside the budget.
Was thinking more something in the range of my old Fine Offset, maybe something with a Colour screen for the hell of it.

Just want to experiment with the Pi for a bit without disrupting the VP/2 while I'm on the learning curve.

If the USB setup is different, it will only leave that to resolve if I decide to move the Davis to a Pi.

You may need to be patient if you want to use Cumulus MX with one of the current crop of FO weather stations.

I have a very old Maplin weather station that was made by Fine Offset and uses a USB port which I have hooked to a Pi and Cumulus MX.
Works like a dream and I only bought another one after I had a period of lost data when the TX stopped working. Weirdly since I bought new kit its been faultless and is still 100 feet down the garden working away!

The modern FO stations as sold by Ecowitt tend to all use the Internet and the USB does not work for data in the same way.
However there is light at the end of the tunnel, in that if you buy a GW-1000 then this will gather the data from nearly all the FO sensors and upload to the internet. But....as a bonus there is or will be a published API that allows other network attached devices to query the data. So in time someone can extend Cumulux MX to use that API and read the weather sensor data into the MX database.

This has been done already by the Meteohub (Edit - should read Meteobridge!) folks as they have asked Ecowitt for the API and have added it their code so that the hub can read the data. I was tempted by the Meteohub (Edit - should read Meteobridge!) but I like Cumulus MX and am waiting patiently. If you are good at coding you could perhaps contact Ecowitt and get the API and add the code to Cumulus MX.

Meteobridge not Meteohub. Different products both by Smartbedded. They were first because I have a Meteobridge and I despised the ObserverIP.

Weather Display is next to have this support. I'm already working with Brian on this. Great progress has been made (not finalized yet). The GW1000 is a really nice piece of hardware. The beauty is that you can run multiple software simultaneously. I'm running Meteobrdige and Weather Display at the same time and both are talking to the GW1000 over the network simultaneously with no data loss. All software get Live data from the GW1000. You don't even need to do anything to the GW1000...other than it needs to be on the network. You don't use the "Customized" server option. That is the power of the API method of data acquisition. Much better than getting data from WU API and better than getting data from AmbientWeather.net API. Because those web connections require the Internet to be up...there is delay in data and that data is not Live in the sense that you are getting minutes old data.
