You can also dim the light via the Link2Home Pro app (Free). Control your home atmosphere via app control or voice. Using the Link2Home Pro app, you can set up precise timers that can be customised by days of the week. Set up countdown timers too. You can group multiple lights together to control one room, one house, or control each light individually. Fully integrated with Amazon Alexa and Google Assistant.
