Is the SpotCable for the Spot Protect wifi sensors a common cable? Do I really need to buy one or do I already have a suitable one?
In short, no it is not. It is a standard USB end on the computer side and an auxiliary plug (headphone or speaker) on the end which plugs into your WiFi sensor. While not technically “proprietary” it is a very uncommon USB cable type.
