Just a quick post to say I've been toying with keeping track of temperatures in the garden and polytunnel. I recently found a neat way of following these with a data dashboard and something called dweets - like tweets for the Internet of Things. I've blogged about some of the polytunnel temperatures before but had previously done all of the analysis offline.
I've managed to got a simple dashboard set up very quickly and have hooked it into the website under the Notes section as Forest Garden Weather Dashboard or you can go straight to it here. The local sensors only update every 5 min so you have to wait a while for some of the graphs to develop but it also combines a local weather feed too so there is some much quicker information. It uses the excellent Freeboard, which is free as the name suggests. It opens a new browser tab as the dashboard gets more informative the longer it is open.
If anyone is interested in the details of getting the sensors set up and everything talking together let me know and I'll post more information. In the meantime here is a snapshot, enough to know that it's cold outside!
Edit - I've updated the image and the link after Andy's comment. Thanks Andy.
