Make switches and pushbuttons smart in no time at all.
So your house or flat is finished and nothing's missing - or is it? Often, smart applications in the home are not planned from the outset, but then you decide you need them after all. But you don't want to replace the expensive switches or pushbuttons with smart ones - and that's understandable! But how about making your already installed pushbuttons and switches smart without having to replace anything? The Homematic IP contact interface - 1-channel also makes your already installed switch smart and allows you to control your Homematic IP devices.
