This grow light's built-in timer needs to be turned on again any time that the power is cut (power surge, smart plug, etc). It also needs its timer to be set at the exact hour when you want it to begin.
I had a spare smart plug that would make it easier to schedule and solve my lights staying off any time the power went out. However, I needed the grow light to stay on after the power was cut. Twist tie? Nope. Velcro? Nope. Dollarama hook that won't hold anything over a few grams on my wall? BINGO
This button is very pushed down now.
I have this model. I assume that the button is pushed down all the time?
Yep! It's always on, then the smart plug controls whether it gets power or not.
