Hi, I just received my WiFi Logger 2 SD and new Vantage Pro2+. I previously had an Oregon Scientific station for about 7 years logging via usb to a Pi.
I have the WiFi Logger set up ok.
Mine has an SD Card slot - so I popped a spare 16GB card in there. However I wondered if this is used at all yet with the firmware - there is no mention of it in the manual or web config.
