I set up a tp-link smart plug and plugged in a lamp with a 3 way bulb...50-100-150w (incandescent). I turned it on the 150w position. Set it up to come on M-F at 5:40am. I tested it numerous times as I had problems at first. Had to install the latest app software before it would use the schedule setting. Every evening I'd ask my husband if it came on. Every evening he said "no"
He finally asked me if I considered it might be burned out. I hadn't. It was a new bulb. He said when you turn on a 3-way bulb it comes on gradually...50, then 100 and then 150w. If I had it set to 150 and it was coming on at 150 (vs ramping up) that could have blown out the bulb. Sure enough, it was burned out. It might mention this in the user manual but "I don't need no stinkin' manual" (or maybe I DO! lol) Anyway, just a FYI
