Weather station uplink

Wed Nov 06, 2013 11:02 pm

Hi folks, I have an idea for a project and wanted to see if Raspberry Pi might be the best way to get it done.

My parents live on a farm, and they have a weather station (uploading to http://www.wunderground.com/weatherstat ... =KCALOMPO9 if you're curious). Up until Monday, they used a desktop PC to capture the data from the weather station for their records and to upload to Wunderground. Then, the poor thing went kablooie.

We could get another desktop pretty cheap to replace it, but I'm concerned about recurring hard drive failure for a device that will be always on and always writing (they've had 2 HDs fail in the past 3 years). They didn't use the desktop for anything else that a cheap tablet couldn't replace, and they have a laptop besides. It's important to them that a replacement keep a smallish form factor and be very quiet. It feels like a Raspberry Pi use case made in heaven.

What I'm looking for is something that will run their Weather Station software (probably http://www.wviewweather.com/) and upload it to Wunderground and back it up onto Dropbox or something. I don't doubt Raspberry Pi can do this, but I'd like to know if we should use it. Will this be more stable and more reliable than a crappy $200 Dell?

Depends on the weather station

http://www.raspberrypi.org/phpBB3/viewt ... 37&t=14777 this might be of some use.

We've used the Fine Offset WH108[01] but the USB link would hang periodically, not much use. So intercepting the TX from the sensors and interpreting them and storing them.

If you've a different station, you might need a different solution. I remember seeing a post here re the Davis Vantage also IIRC.

Hi,

I have done this for a Peet U800 weather station here:

http://www.raspberrypi.org/phpBB3/viewt ... 2&p=381562

This sends to CWOP, but wunderground could be done fairly easily.

If you're able to cut some PHP and the mod the shell script/cron job, you may be able to drive the Serial/COM port to the Davis logger interface (assuming you have a serial version and not the USB version).

When I can afford a Davis setup, I'll no doubt write the code to poll it. Until then I offer this as a suggestion.

Good luck!

Regards, Darren

Thank you both for your help and responses. I ordered my Raspberry Pi a few days ago, so we'll see how this goes. The current plan is to just install Raspbian and wview, which says it supports Debian Wheezy on armel architecture. If that doesn't work, I may need to get a bit more creative.

I've been using a Pi Model B, WH1081 and PYWWS, 12v 175Ah Battery, 190W of solar panels and an Optus WiFi Broadband modem since March this year at our property with no mains power. Still going strong. Going to replace the B with an A shortly to save even more power.

And I have another model B similar setup but on mains power and a WH3081 at home.

Great fun project to get involved in, and quite cheap.

FYI! wview is not in the official repositories, though it is likely someone has configured it to install/run !

Debian Wheezy is for ARMv7 whereas the Pi is ARMv6 architecture, hence why the RPF recommend their Debian based Raspbian Wheezy which is ARMHF
Pi Forum Search and Google yields answers to many questions

I can't seem to find a wview build for armhf. Is there one floating around?

FWIW, I am running the latest Raspbian build (20 Dec).
Tnx.
