Homematic IP is expanding its smart home portfolio with the new Access Point 2. But what are the differences between the compact entry point and the powerful Home Control Unit? Taking a look at the key differences reveals which device is best suited to which application.
Getting started made easy with the Access Point 2
The Access Point 2 is the simplest way to set up a Homematic IP smart home, making it ideal for flats and smaller houses. It can be set up quickly via the app: simply connect the router and scan the QR code. All devices communicate securely via radio, and registration is not required. Up to 120 components can be integrated and the range can be extended by adding up to three additional access points. Certain components also enable direct linking, ensuring they function and communicate reliably with each other when used with Access Point 2, even without an internet connection.
Home Control Unit: maximum flexibility and future-proof
The Home Control Unit goes far beyond the cloud-based solution: it can integrate up to 350 Homematic IP devices. Automations run locally, meaning the system also works without an internet connection. The Home Control Unit also offers energy monitoring and measurement data acquisition, as well as an EEBUS interface for integrating heat pumps, wall boxes and air conditioning systems — a decisive advantage for future-proofing your smart home infrastructure.
