The TOP FAQs

In the FAQ section, you will find answers to your questions about eQ-3, our products and technologies.

    • Which protocol does Homematic use?

      The Homematic protocol has been developed by eQ-3 exclusively for applications in smart homes and buildings. The development is based on more than 20 years of experience. Technically, the Homematic protocol is a bidirectional radio protocol. That means, that every receiver is able to confirm a command to the transmitter.

    • How many Homematic devices can I use in my installation?

      It should be considered that the Homematic system has been specified and developed for a “normal” family house. For installations in larger buildings, we recommend e.g. a cooperation with our partner Contronics.

      The system limits per Homematic Central Control Unit CCU2 are specified as follows:

      • 400 radio channels and
      • 127 wired devices in addition.

      Please observe the following:
      The number of wireless devices depends on the number of channels of all used devices!

      Example:

      • Homematic Wireless Switch Actuator 1 channel has one channel at 400 devices
      • Homematic Wireless Switch Actuator 4 channels has four channels at 100 devices  

      Usually, different devices are used within one installation. From our experience, the maximum number of wireless devices that can be operated trouble-free by the CCU2 within one installation is therefore between 100 and 120 devices.

    • Where can I buy eQ-3 products?

      eQ-3 products like Homematic, Homematic IP and MAX! are distributed by numerous partners. This applies to partners in mail-order business such as the German companies ELV and Conrad Elektronik as well as retailers, installers, system integrators or OEMs, who integrate eQ-3 products into their own solutions.
