Setup HomeKit Bridge

More info

  1. Configure your proServ with the corresponding ETS product database. (Product database may be downloaded here – section more info). Test the configuration using our iKnix2 app.
  2. Connect your realKNX Server to the network (or restart it, if it was already connected)
  3. Wait 5 minutes
  4. Start the realKNX application (available on iOS AppStore)
  5. Create your home (clicking on the + at the upper right corner)
  6. Click on the new entry and add a device (clicking again on the + at the upper right corner)
  7. Select the entry “KNX HomeKit Bridge” (If you do not see this entry please refer to the troubleshooting section)
  8. Select the “manual pairing” by clicking on the text link at the button of the page
  9. Enter the pairing code 111-22-333
  10. When pairing is done select the flash back to your home – you should see all rooms and functions now. Test Siri now 🙂

If you modify the ETS configuration, restart the realKNX server after downloading the product database. Wait 4-5 minutes, start the realKNX app and select your home. All modifications are updated also for HomeKit, a new pairing is not necessary.

The realKNX app is only used to sort the functions in the appropriate rooms. Siri is working even if no app is open.

How to find the right words for Siri

Autre manière de dire ‘allumer’: ‘ouvrir’, ‘mette en route’, ‘met en marche’

More info

Siri has to be enabled in the settings of the iDevice. The chosen language should correspond to the language used in the ETS parameter.

Siri allows to control and to query KNX devices. Siri knows with the chosen words if it should look in the internet or within HomeKit for the answer.

  • Device specific voice commands, e.g.  “Switch on the ceiling lamp in the living room” or “Set the blind in the kitchen to 35%” or “Set the thermostat in Peter’s room to 21 degrees”
  • Group voice commands, e.g. “Switch off the lamps in the living room” or “switch off the living room”.  This is possible without having defined scenes on the basis of KNX. In the latter example, all switches will be turned off, not only lights.
  • Voice commands – relative operation, e.g. “Increase the brightness in the living room by 10%” or “increase the temperature in the kitchen by 1 degree”. These commands will use the actual value as basis and will add the asked value to define the new setpoint.
  • Voice commands  – state queries, e.g. “What is the pool temperature” -> Answer: “The pool temperature is 23.5 ° Celsius”.
  • Voice commands  – check the entire installation, e.g. “Are the lights on in the house?” -> Answer: “Three lamps are switched on, the others are off”
  • Siri supports many languages (35+ )

The words that are used to communicate with Siri are defined in the ETS parameters of the proServ product database.

  • Do not use abbreviations
  • Best words are unique single words
  • You may always check the spelling of the words when you open the iKnix2 app

Automation functions and remote connect with HomeKit

More info

  • Automation support – when configuring an iOS10 iPad or AppleTV (3rd or 4th generation) as a stationary device in the house, automation commands can be triggered. Read more at Apple support Automate and remotely access your HomeKit accessories
  • Geofencing support – geofencing is a virtual perimeter for a real-world geographic area. Leaving or entering the perimeter can be used as trigger for automation, e.g. Trigger “Switch on lights” when entering home.
  • RemoteConnect is supported – without configuration of VPN or port forwarding – you are simply connected to the installation with or without Wifi (only possible with stationary Apple TV or iPad)
  • Push information may be sent for binary infos (1 Bit state in ETS product database). This has to be enabled by selecting the alarm in “Home” application

Troubleshooting HomeKit

More info

Known HomeKit issues

More info

  • You need to have at lease iOS9 (better iOS10) running on the devices
  • HomeKit Bridge works with a limit of 99 functions. The first 99 functions will be imported. If you need to unselect a function please add #h to the function name! To reach lower update times in the HomeKit apps, define a minimum of functions for the Bridge.
  • If you are using special characters in the zone names (rooms) or function names these will be omitted. Please use complete words for better Siri understanding
  • Unfortunately the update time of the origninal “Home” app is very long. We recommend to use our “iKnix2” app to control the installation.
  • A rather fast and nice HomeKit app is “Eve”. The only issue we have found is that the state of binary values is shown reversed
  • In the actual version 1.2.4 of our HomeKit package the following proServ functions are not supported:
    • RGB (except RGB single objects function followed by a dimmer or switch function)
    • shutter without feedback
    • KNX scenes (use AUX 1Byte instead)
    • Controls
