I've just got the OurWeather V2 kit and had had a couple of issues setting it up.
When I powered it up and connected to it via it's own internal access point the configure wifi page didn't have all the fields listed in the manual. If I remember correct it only had details to connect to my own wifi network. There were no options to set the station name, set the date/time or altitude.
Then after it rebooted and connected to my wifi I just can't get it to connect via the OurWeather page (http://www.switchdoc.com/OurWeatherPage.html). I've entered the IP address the device has connected on and then clicked the Get Current Weather button but it just sits there saying not connected. I can see the device registered on my wifi
