Well, if you ever get round to making your garden monitor a web interface, I'd love to see it! That website you've got is awesome!! What are you doing with all that information? You could literally write weather prediction software with such extensive info (depending on how long you've been logging it for I guess).
You could probably also sell it, if you found the right person.
Have you considered using prettier graphing software? Something sleeker and more modern :33
And finally, what other awesome projects are you working on? I've considered setting up a weather monitoring system myself, so maybe you've done something else I'd love to try
