Finally found this thread........I have 4 fixtures and one of them keeps flashing red..... I did the factory reset...... It stop flashing but started again the next day.... Any help would be appreciated...
Mine did that too.
Do the lights turn on for a <second and then flash red? it might be only one or two leds.
It's likely dead. I would encourage you to contact ecotech. They should replace it for you. I too a video of the issue. They were very helpful
