To enable your Control4 to play Chromecast Audio you need to buy a Chromecast Audio device and follow these steps.

  1. Setup the Chromecast Audio device as usual, join into your WLAN
  2. Connect the Chromecast Audio on any analog input of any Control4 Controller
  3. Add this modified Chromecast driver to the Project and connect in Composer the audio output to the Controller input. Its name will be shown in Composer as Chromecast Audio. nocontrol_google_chromecast_audio
  4. That’s it. Refresh Navigators and enjoy!

How to replace GT KNX dimmer and switch drivers by C4 dimmer and switch drivers

The process is identical for switch and dimmer, in this example we take a look at a dimmer driver which needs to be replaced.

  1. Make sure you have updated the driver to Version 10.6.2 or higher. Go to Driver -> Add or update Driver and select the driver file.
  2. Check version by right clicking on the driver
  3. Refresh the project in Composer by pressing F5 or File -> Refresh
  4. If the version is correct add a new KNX Dimmer driver from the online database to the project.
  5. Jump to the old driver and select in the popup window of the Property Replace with C4 Dimmer driver the new inserted KNX Dimmer driver.
  6. Press Set
  7. Jump to the new driver and see if all Properties were correct transferred.
    The driver name also is taken over, and the old driver is marked with obsolete.
  8. Buttons connected to the old driver were also transferred to the new driver
  9. Delete the old driver, AFTER you have checked Programming if there is anything to do.

myStrom devices integrated in Control4

The Swiss manufacturer myStrom has developed a attractive range of simple WiFi devices to connect to automation systems like Control4.

The device range includes:

  • Bulb for E27 mounting
  • LED Strip ballast/controller
  • Power switch for direct socket mounting
  • Button for simple task automation

Today the complete Control4 driver suite for all myStrom devices is released, find all details on the product page

Setup myStrom WiFi Switch for use with Control4

These are the steps to setup a myStrom WiFi Switch for use with Control4.

Good to know:

  • Some steps may take some seconds, make sure the phone does not go to standby. If it does the app does fail at that step. Hold your finger on the screen.
  • Once set up, the steps in Control4 are easy to take
  • App and C4 can be used in parallel


  1. Download the myStrom App
  2. Open the app
  3. Go to the menu and select Add Device
  4. Add a WiFi Switch
  5. Select to setup manually
  6. Select the WLAN of the WiFi Switch (after reset and out of the box the Switch is a accesspoint
  7. Connect and after a few popups (select the popup from myStrom App to continue) select the use of fixed IP Address
  8. Enter the WLAN key and as well the IP address settings
  9. Select the green arrow to complete your setup.
  10. Go back to the main app screen and let run everything for 10 minutes, there will be firmware updates shown. Update firmware using the app .
  11. Relax and insert the driver into Control4. See the drivers Documentation tab for next steps


Howto add conventional door intercoms into Control4 using Symetrix

This howto bases on this environment:

  • Control4 system with EA-5, OS 2.8.2
  • Control4 touch panel Wall-10 and TT7
  • Universal SIP Doorstation driver (intercom_universal_doorstation)
  • Symetrix Radius EX with 2 Line VoIP Interface Card
  • Control4 driver for Symetrix matrixes, available on this website
  • Door intercom with analog audio in/out,  contact and a relay for control (Nothing brand specific)

Task description:

Existing buildings do often have intercom systems built in which are most likely not integrate into a SIP system like Control4. Various brands and techniques, often country specific manufacturers, old installations are already present in the field. Nevertheless Control4 customers are living in such buildings and want to integrate the door communication into the Control4 system.

Analog interfaces to get/send the audio and I/O’s are often available for this kind of installations, or can be engineered with very little effort. Using these possibilities Symetrix can act as interface between that analog and the SIP world of Control4



Control4 setup

Add the appropriate driver from the library. If a doorstation interface is wished take the Universal SIP Doorstation driver, else the Universal SIP Phone and add it to the project.


Make sure to set username and password for the SIP accounts, later on we have to insert that into the Symetrix config too, so write it down. Afterwards go to Actions and press Idle State.
If a camera is present add it to the system and select it as alternative camera, select the door interface buttons to be active and insert the text that should appear on the Navigators




Go to Agents and make sure all devices are in idle state an there is a group with a number defined which we will use as group to call on a doorstation event, for example group 22


Symetrix setup

Insert the VOIP card and make sure that its recognized by the unit. Open the design on the Radius EX by double clicking on it. Two new modules appear, both named with 2 Line VoIP Interface.


Minimum configuration is to connect the 2 VoIP modules to input/output as shown above. For sure other modules can be connected, such a supermodules or other to get a smarter config…

A double click to the bigger one of the two 2 Line VoIP Interface will bring up the VoIP module interface to manually take/do calls. Insert there the group we will call on C4, in our example group number 22. Also right click the number in front (marked in red) and assign a control number, 9000 in this example. Do the same for the button Call/End with another control number 9001


To continue our setup, press Configuration Settings, a new window open with the status messages of our running VoIP configuration


Again we have to go a step further by pressing VoIP Web Admin to be launched on the preferred interface, most probably on the AV Network
A new browser window opens with the effective SIP configuration pages. First set the IP of the VoIP module to a decent one.


Jump over to the SIP settings and set the codec priority, G722 does provide the best quality


Afterwards set up the SIP accounts with username and password noted before.

CropperCapture[996]CropperCapture[997]CropperCapture[998]Once all setup is done the left side status messages should display Registered on the setup lines

Jumping back to the VoIP module interface we can try to do a call and as well to take calls. Try both ways to ensure to get audio both ways

Triggering a call on contact closure

Connect the contact lines from the 3rd party doorstation to a Control4 controller and insert a Single Contact using Composer, in Connections connect it to the hardware where the cables are connected. Using the matrix driver (well if it is not present in the project its now time to drop it in and do all settings that it runs, see the driver manual on ho to do this) we enter the 2 control numbers 9000 and 9001 as raw subscriptions


And in programming we setup up that the contact closure does send out the control numbers


If a end of call is provided by the doorstation the control number 9001 can be sent in the same style with the value 65535 to end the call

As alternative also an analog input from Symetrix can be used and trigger directly the control number.

Open the door

A single relay can be added and connected to a hardware relay, wire the cables to the doorstation relay input. To open a door with the door interface buttons simply add a task in programming which closes the relay


Don’t forget to open it after a few seconds, otherwise the door will be open forever.


How to activate and check the Control4 Directors log for debug reasons
