Can I turn off the night light feature?

The LED lights on the Onelink alarm not only provide a nice glow to light up your route, but they also indicate that the alarm is receiving AC power. You can adjust the brightness level of the nightlight through the Onelink app. When you disable the nighlight two LEDs will glow green on the Onelink alarm letting you know that you have AC power. If the LED is turned off, it indicates your alarm is running off of battery backup.
