In conjunction with the Homematic IP contact interface, potential-free buttons can be integrated into the Homematic IP system with little effort. This means that conventional buttons can be flexibly retrofitted with Homematic IP functions and devices in order to intelligently control lights or roller shutters, for example. Thanks to the compact housing, the contact interface can be flexibly installed in a flush-mounted box. Existing switches or switch series can continue to be used without any additional installation effort. Switches and magnetic contacts can also be linked to the contact interface using the free Homematic IP smartphone app to enable convenient wireless communication. The long-lasting, replaceable lithium battery has a lifespan of up to 2 years - there is no need to connect the device to the power supply.
