I too am having issues with my Noopsyche light, but I'll tell you what worked for me so far.
FWIW, the paperwork instructions do not match what I see on the Noopsyche app.
To connect my app to the light, I had to put my light into "AP" mode by tapping the "R" button on the front of the light. Then I had to connect my phone to the Wifi network labeled "K7_Pro...". I presume this is a low power network hosted by the light. I can't recall if I ended up using my home router password or the Noopsyche factory password to make the final connection. I tried both. At this point the light is operational, synced time wise to my phone, and allowed me to select between sps, lps, or sps/lps auto mode. Unfortunately I can only connect to the light with the app if I switch to the K7_Pro... "wifi network". I'm not sure if that is proper or a bug.
