The Homematic IP control unit, often also referred to as the „Homematic IP Access Point„, is the heart of the Homematic IP smart home system. It acts as a central hub that enables communication between individual Homematic IP devices in the home and the cloud. The control unit not only connects the devices with one another but also links them to the internet, allowing them to be controlled from anywhere through the Homematic IP app.
However, there is another control unit within the Homematic ecosystem: the CCU (Central Control Unit), such as the Homematic Smart Home Central Control Unit CCU3*. This control unit is designed for the broader Homematic system and can control both Homematic and Homematic IP devices. The CCU offers more options for custom programming and local control without requiring a cloud connection.
Which Homematic IP Access Points are available?
The Homematic IP Access Points form the interface between the various wireless sensors and actuators in your Homematic IP smart home system. A distinction is made between the Homematic IP Access Point* and the Homematic IP WLAN Access Point*.
With Homematic IP Access Points, the smart home system is processed and controlled through Homematic’s servers. An internet connection is therefore required to use the full range of functions. Configuration and control take place through the Homematic IP app, which is available for Apple and Android devices. The two models differ in how they connect to the internet: either by LAN or Wi-Fi.
