After I stopped trying to find a template and decided to just do it on my own I managed to come up with this (attached).
I still find the editor extremely primitive, but it's workable. I got an image off the 'net, edited it to make the aspect ratio correct and then just added the sensors.
The panel is excellent. Too bad no one makes a case for it for sale. I know that place in the UK makes one, but they only seem to sell it with the monitor. If I could have purchased it separately I would have.
