@Mañ'O'Green We actually thought about this a lot. We saw the testers struggling to hang the devices in the optimal places -- the center of the canopy. It's the hottest area (under the lights) and the area you care about the most (cola zone).
Having two "cords", one for power and one for hanging, seemed like an unnecessary mess. So we made sure the device could be self supported with the power cord provided. Feel free to hang it from the usb cable into your canopy

Hey-- and every grow is unique. The idea is that the device is flexible and you can power & position it as needed. If you need a longer cord, it's a standard microUSB for power so options for a bigger cord, battery power, or extending with a 2-prong extension are options.
I like to position mine on trellis. My personal grow is not as impressive as this Pulse user's but just another example:
