There's no description how basic LED works.

Sorry if there is, but I couldn't find out how LED works when there's no problem.
I had same problem of what jacintosh says here. ("http://www.reasnow.com/forum/index.php?topic=2639.msg6681#msg6681")
It was PS4 cable issue but I misunderstood for a while because the LED looks green. I checked this. "https://www.reasnow.com/download/ReaSnowApp/Warning%20and%20Solution.pdf"
I thought I had to buy a new one. But I realised LED is breathing and was actually yellow in the end, which a color a user can change in App.
Like... he thinks LED color is green in the topic above. sigh...

if the LED is breathing, it means S1 is working well.
if the LED is flashing red, it means S1 is working well but you need to run our APP to add a config to S1.
for others, please check the "warnings and solution" document.
