Review on KNONEW Outdoor Christmas String Lights: 1000 LED 403ft 🎄 with 8 Modes & Timer for Home Xmas Wedding Party Decorations by Djkutt Mack

It saves the last function setting as long as the function selector is on and you turn it off with the remote control. The default power on state is with the light on and COMBINATION mode selected. So attaching them to a wall switch or Wi-Fi switch will result in the most annoying flashing lights when you turn on the device. You will need to use the remote control or the function selector to navigate to 8 = PERMANENTLY ON, which should be the default mode and is the default mode for some other vendors' lamps. Otherwise, that's a lot of little lights for my big attic. It's possible to leave it plugged in if you keep the remote handy, but if the power goes out you'll have a flashing light show when power is restored. The neighbors will be entertained by your luxury home.
