Can I plug any electrical device to the Wiser Plug?

Most household appliances can be used with a smart plug, as long as they are rated for max 3kW. We do not recommend plugging medical devices or other critical household appliances like a fridge or a freezer. For heaters, only connect heaters that have an internal thermostat, overheat protection and a built-in safety trip switch. Make sure the appliances are not covered or obstructed in any way. If remote access or internet connectivity is lost, ensure that somebody can access your home to turn devices off.
