New slug, new wview

My nslu2 (slug) died at the end of last month. I’m not sure if it was a hardware or a software fault but I have replaced it with a very cold stand-by I had purchased for just such an occasion. I backed-up the hard-disk used by the first slug; installed Debian Lenny from scratch; and took the opportunity to install wview 5.7.1 using the Debian install script. Everything just about worked fine (couple of minor issues: htmlgen was being killed by the process monitor before it had apparently got a chance to get going; the Archive and NOAA directories had to be manually created before wview could write any data to them). I have also registered with the AWEKAS weather service and installed the iPhone template.

Slug update

Clearly I’m not a blogger at heart. I actually installed Debian on my NSLU2 on 30 March (using the cookbook at http://www.cyrius.com/debian/nslu2/install.html). Connected to a 500gb MyBook everything worked fine. I installed wview and configured it to use the in-built simulator (for testing). That worked fine too (with Apache serving up the results). Well, it worked ok for four days and then I started to get broken pipe errors from one of the radlib message queues. No matter, the concept had been proven.

Then both the Davis data logger and the wireless envoy arrived. Thus I spent yesterday updating Debian (especially openssl); replacing apache with lighttpd; and reinstalling wview to work with the Vantage Pro weather station rather than a simulator. In the first instance I’ve connected the VP2 console to the Slug. This also seemed to work as it should and I even managed to set the archive interval rate on the console via the slug command line.

So the basic setup is complete (http://slug.begbroke.org/). Next steps are to:

Retrieve historical graph data from the VP2 (seemingly easiest to do with the WeatherLink software, so must find working Windows system…);
Connect wireless envoy and put the console back where it should be.
Start customising the wview html templates.

I have a feeling I will have problems with historical data and archive intervals…

Vantage Pro2

The Davis Vantage Pro2 weather station has been in operation for just over a year. Only I can see the console and access the data on rainfall, barometric pressure, temperature, wind etc that it’s been collecting and displaying. Hopefully, that will change soon. My intention is to connect a console to a Linksys NSLU2 with (probably) Unslung and wview installed. All the bits, including the datalogger and NSLU2 are on order.
