Thanks nattfoedd - I'll look into it. However as a newbie programmer I suspect I'm not quite at the level to implement this myself. Has anyone written python code that interacts with this site that I could look at?

I've built the weather station and wanted to post my data to a website. Tinkerforge have python code to do this using xively. However when I try to create an xively account I've been put on a waiting list. Is there any alternative that a newbie pythoner would be able to implement? Many thanks!

Problem solved - many thanks borg!

A very new python programmer here who has built the Tinkerforge weather station connected to a Raspberry Pi. I am starting to tinker with the Tinkerforge code and want to implement the is_backlight_on function for the LCD. I more often than not get a timeout error when I call this function; sometimes it works but mostly not. Any help would be appreciated for a newbie!
