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.

    • Are the systems manufactured by eQ-3 compatible with one another?

      In the browser cache, the web browser temporarily stores websites and pictures. If websites are visited frequently, the data does not need to be downloaded from the Internet again. In this way, websites can be displayed faster. During the firmware update of the Homematic Central Control Unit, some data of the CCU2 that is stored temporarily in the browser cache will be updated. To avoid any problems during the update of a new firmware version we recommend to clear the browser cache after each update.

    • How secure is Homematic IP? Can it be hacked from the outside?

      Homematic IP takes the security in home control to a new level.
      Even the teach-in procedure is cryptographically secured. Unlike other radio technologies such as WLAN, Bluetooth (devices without display) or ZigBee, Z-Wave, DECT, ULE and EnOcean, it is not possible to intercept keys during installation.
      During operation, data packages are encrypted and authenticated. Therefore, we rely on generally accepted and published standards such as AES-128 and CCM/RFC3610.
      Also the communication between the Access Point and the Homematic IP cloud, as well as the connections between the app and the cloud, are securely protected by online security procedures.
      The security concept and especially the radio protocols have been tested by renowned and independent experts in the field of security. For example, the climate control solution of Homematic IP has been rated “very good” by the test lab AV-Test.

    • 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.
