  • Is it possible to use Homematic IP devices and functions with Amazon Alexa routines?

    With Alexa routines, multiple actions can be executed with a single voice command at the same time or at a specific point in time.

    In connection with Homematic IP and Alexa routines, it is currently possible to switch on several Homematic IP devices, such as switching actuators for lighting, at the same time. When switching lights via dimming actuators, the dimming value of lights can also be adjusted in percent. In addition, the activation of the eco mode in Alexa routines can be included. Further functions in connection with Alexa routines, such as the integration of shutter and blind actuators, will continue to be expanded in the future.

  • Which Homematic IP functions are available during active or inactive Internet connection?

    Set-up and control of the Homematic IP system is carried out via the free Homematic IP smartphone app in connection with the Homematic IP cloud service.

    In comparison with other systems, Homematic IP actuators offer the benefit that cloud-dependent functions like heating or time profiles as well as the communication of single devices with each other remain functional also without active Internet or cloud connection thanks to an integrated memory of the devices. Cloud-dependent functions are all rules created with the “automation” function, shutter configurations like lockout protection, storm protection, heat protection or escape function as well as the integration of voice control. They are verified in the cloud and require active Internet and cloud connection at all times. It is recommended to connect Homematic IP devices via group functions, like light and shutter groups, for example. On the one hand, the radio traffic is reduced. On the other hand, the connections created via groups remain functional also without connection to the Internet.

    When using voice command services like Amazon Alexa or Google, it is also recommended to use Homematic IP remote controls or push-buttons for controlling your devices to enable switching of your components also without active voice control. 

    The following file gives an overview of available functions with or without active Internet connection:

  • What has to be considered with regard to interferences when installing the CCU or Homematic IP Access Point?

    Every electronic device or any current-carrying conductor builds up an electromagnetic field. These fields occur in a wide variety of strengths and frequency ranges.

    This applies in particular to objects that emit radio waves:

    • WiFi routers
    • DECT stations
    • TVs
    • Computers
    • Radio speakers and radio headsets
    • Audio and video systems
    • Alarm systems
    • Mobile phones and cordless phones
    • Microwave ovens
    • Electronic ballasts for fluorescent lamps
    • Audio baby-monitors
    • etc.

    These interferences can be substantially reduced by keeping a distance as large as possible between the radio components and those potential sources of interference.

    We recommend a free installation site for the Central Control Unit or Access Point without the above-mentioned sources of interference in direct vicinity (ideally at least 1 m distance), in order to achieve an optimal wireless coverage.

  • Why is it not possible to control my Homematic IP Shutter and Blind Actuators via Google Assistant?

    The implementation of voice control systems on the market is realised via interfaces offered by the manufacturers. Depending on the provider, different functions and possibilities are supplied.

    Currently, Google Assistant unfortunately does not yet contain any voice commands for controlling shutters and blinds. As soon as the function will be provided by Google, it will be possible to control your Homematic IP components as well.

  • Is it possible to control Homematic IP devices without Homematic IP Access Point via Amazon Echo devices with integrated smart home hub?

    The integration of Homematic IP with Amazon Alexa takes place directly via the Homematic IP cloud, that is, in principle, via the Homematic IP Access Point.

    The Amazon Alexa device variant Echo Plus supports a variant of the ZigBee protocol, which directly supports Philips HUE lights. With other Amazon Alexa devices, also an additional gateway is required for Philips HUE.

    Thus, the cheapest way to set up voice control with Amazon Alexa is an Amazon Echo Dot + Homematic IP Access Point.

  • In which languages is the Homematic IP app available?

    Currently, the app is available in German, English, French, Dutch, Italian, Spanish, Polish, Russian, Danish, Finish, Swedish and Norwegian.

  • 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.

  • What does “IP” mean? Is it possible to integrate all IP devices (e.g. VoIP phone IP cameras etc.) into the system?

    All Homematic IP devices communicate via IPv6 or more precisely via UDP/IP. Using IP, all devices in the smart home can be operated within one network and be combined via corresponding applications.
    That means, that e.g. IP cameras can be integrated into the Homematic IP solution if the corresponding application supports the Homematic IP protocol. In the future, also other communication media will be supporting Homematic IP as radio technology for other devices.

  • 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.

  • For how long will the software (app) of Homematic IP be maintained?

    A regulation that ensures our customers the long-time operation is part of our Terms of Use.
    eQ-3 is known for supporting its product lines for a particularly long period of time without any compromises in terms of backward-compatibility. This is for the example the case with FS20 since more than 15 years and now 10 years with Homematic.

  • Will the Homematic IP devices be integrated into existing Homematic apps (Penzler, Orbylon, HomeDroid, Home24, Mediola, IP Symcon, Homeputer)?

    Yes, this is already possible with a majority of Homematic apps.
    The technical requirements are already in place and Homematic and Homematic IP are compatible with the CCU2.

  • Does Homematic IP support different time zones?

    Yes, different time zones are being supported. The times of the week profiles are always based on the time of the Access Point location, this means the time zone that has been configured for the Access Point.

  • Do I have to expect running costs? If yes - to what amount?

    No, there are no running costs such as server rental costs, costs for apps in the app store etc.
    It might be possible - but currently not yet planned - to extend the free app by additional services with in-app purchase possibilities.
