I recently purchased a Hubitat C-7 but it appears to be dead on arrival. I plugged it into my router via the included ethernet cable, then connected power - no lights or any indication of functionality after several minutes. I submitted a warranty request yesterday but was curious if a post might provide answers/move things along.
Update: I don't have another power supply readily available but I did get to thinking that any USB port should provide the necessary 5V. Indeed, I re-connected to the router and a USB port on my PC and got a blue light, red light, no light cycle followed by blue light, stable green light. Additionally, I can find the hub via the network. So I guess the power supply is DOA.
