Control up to four mains appliances in your home or small office using an App or by voice using your Google Home or Amazon Alexa. For example, with a simple touch on your Smartphone or voice command, you could turn off the TV without getting off the couch. You can also set up multiple schedules to turn appliances on automatically at different times, ideal for turning on lights to deter thieves, or for turning on your coffee machine in the morning. A smart timer or delay is also useful to turn devices on or off. There are also two high-current USB ports to conveniently charge two USB devices without having to use up any of the mains sockets.
