With the Homematic IP switch and meter socket (HmIP-PSM-2), connected devices can be switched on and off at any time and from anywhere. The switch socket switches almost all conventional electrical devices as desired - via Homematic IP buttons and remote controls, via voice command, directly on the device or via smartphone, whether at home or on the go. The measuring function means that no unnecessary energy is wasted, as the consumption values and costs of connected electrical devices can be viewed via the app. This makes it easy to identify energy guzzlers in the home.
