Arghhhhh! you did a post whilst I was writing!!!!
I'm planning to build a small stevenson screen to set up in the back
yard. Original idea was to use motion on a pi to see hat the pup is up
to and also diplay temperature and humidity in the video stream from
motion. It turns out motion will only display date time etc and I can't
ad text from a second source. So my idea is to set up a dynamic web page
which updates tmp. an hum.periodically and is available just by typing
in ip:port_no. Maybe later figure out how to embed video on the webpage.
