@TomWS,
I have a running thread about my unit in the Projects section. It's one of the "saved" projects so it should be near the top.
By widget do you mean physical sensor, or software component, or both?
The indoor base station Mega receives the outdoor transmission and is serially connected to a Spark Photon. From there it's a wireless connection to the Internet. The Photon uses the "publish" feature to upload JSON data to Freeboard, a free tool that I use to visualize the data.
Did that answer your question?
