As Russ has sent me back my old Eee 701, I decided to set it up for the weather station. I had to install the FreeWX-Wi 1.02 beta to get the outside temperature (and humidity and pressure) probe to work, but now it's passing data just fine. I've put the sticker on my home page, but all the data's here.
I think I'm going to see about getting the data from the TED-5000 uploaded somehow, as the Google are giving up on Powermeter.
Having got that working, we sat and watched The Mechanic.
