Thanks much for your patience, I had a chance to look at your account / Pi and I think I see what the issue is.
Your Pi is running the 4.9 Linux kernel, and webiopi (which is a software we use to control/monitor the GPIO pins on Raspberry Pi) only works on the 4.4 kernel that's part of stock Raspbian Jessie currently.
You can see your kernel version by running the command
uname -a on your pi.
We are planning to update webiopi (we actually hired the developer at our company ), so when Jessie moves to something newer than 4.4 we'll be there to support it.
In the meantime, if you don't have specific need for the 4.9 kernel, you can downgrade to 4.4 or do a fresh Jessie install, which should include 4.4. Either way I suspect you'll have much better luck creating this widget without the 'Unreachable' state.
