Show documentation available on device at wifistepper.com

[cmf]

It would be useful to have the documentation that's available on the web UI on the device also available at wifistepper.com. In particular, the details of the power supply requirements (e.g. barrel size and whether it's centre positive) are only available there as far as I can see, and are not mentioned in the getting started video either. As a relative electronics newbie that took some figuring out. Having those details available on the device doesn't make a lot of sense, since you have to connect the device to power to see them :-).
