How does ayControl communicate with my devices?

ayControl uses WLAN and LAN to exchange information with connected devices.

The following facts show the advantages of this solution:

  • mobile devices are usually equipped with an built-in WLAN
  • most homes are equipped with WLAN
  • many devices have a possibility to be connected via LAN
  • the connection between WLAN and LAN is virtually always present
What is a “controllable device or system”?

Any piece of technical equipment that has the possibility to send and receive data from a network is seen as a controllable device or system by ayControl. This is often possible with an extra component: KNX bus with KNX/IP gateway, an IP interface for DMX, etc. The data between the system and the network can also be exchanged via an extra transceiver, e.g. IR Trans for devices with infrared remote control. Of course, the device itself may happen to have a network port over which the data can be exchanged.

How can I control my KNX bus system with ayControl in only a few steps?

There are just seven steps to control you KNX bus system with the ayControl on your mobile device:

  • download ayControl 3 from the Apple App Store/ Google Play Store
  • download the ayControl Editor from the download page, install it and start it
  • create a new ayControl project
  • create a new KNX connection and import and prepare the group addresses
  • create control elements and bind them with the group addresses
  • create a profile structure (floor, room, layout) and place the control elements
  • transfer the project to your mobile device

Now you can turn on or off the lights for the first time with your iPhone, iPad, iPod touch or Android smartphone or tablet.

If you have any problems with any of these steps, you can find more detailed video instructions in our video academy

Another important part is the superior support for every of our customers, offered by our employees and our retail partners.

Bus systems and their mobile control need a variety of different components. In order for them to work properly, the configuration needs a lot of knowledge and experience, which is offered by our KNX experts and retail partners.

Can the ayControl communicate with the SIP based IP door station?

Yes. Not only that it is possible to speak with the visitor and to open the door, it is also possible to display a video stream from the door station. When the visitor calls from the door station, a pop-up window is opened and the video stream is displayed.

Furthermore, you can connect IP-cameras. This way you can always keep an eye on your home/building. One or more IP-cameras can be easily embedded offering you security and information.

Can the design be changed?

Yes. The graphical user interface of ayControl was created by professional designers and it’s adjusted for easy handling and recognition.

How does the control of multimedia devices over ayControl work?

The control takes course directly over a IR gateway, e.g. IR Trans Ethernet or SC LAN IR-I/O which converts commands from LAN to infrared.

It is simply configurated by creating a user interface. The commands for the multimedia remote control are recorded directly by the learning mode integrated in  ayControl. This way it is not necessary to search for the raw IR commands and the configuration takes only a few minutes.

Why do I get the “configuration could not be loaded” error?

You have probably exceeded the limit of the allowed elements. As described in the App Store/Play Store and on the, the ayControl iPhone/iPad/Android base app only spports up to six elements (including control elements and labels).  Would you like to work with bigger projects? No problem, ayControl also supports projects with hundreds of EIB/KNX elements. Here you can find information about ayControl upgrade possibilities and where you can get them.

How many devices can be connected at the same time?

Normally, the number of connected devices is not limited, but this can depend on the converter between KNX-Bus and IP network (the gateway) and the protocol that is being used:

  • KNX/IP routers in local WLAN support any number of devices but only few (mostly one) over the internet
  • KNX/IP interfaces offer only one connection in most of the cases
Does my PC need to be on all the time?

No, the ayControl communicates directly with the KNX bus and needs no server. A PC is needed only at the beginning for the configuration and setup of the ayControl. This way the costs of the equipment acquisition, maintenance and energy are reduce.

This page lists all the details about the technical requirements

How does the logging system work?

The protocol or the logging system records the send/receive activities that can help our support team to resolve a problem. Depending on the level the detail amount varies: “Error” is the most general and “Debug” the most detailed protocol. The logging should be off when it’s not needed since it affects the speed of the application.

The setup for the logging system can be found in the system-wide setup under the “ayControl” entry

How do I create and send a log file?

In order to create and send a log file you need to go activate the logging in the system-wide setup and set the level to “debug” if not indicated otherwise by our support team or your sales partner. After you have activated the logging go to the app and repeat the steps that led to an error. In the following steps there are slight differences between ayControl 2 and ayControl 3:

ayControl 2: 

In the room overview  tap on the “View log” and a new window will pop up. Tap on the action button in the upper left corner of this window and select “Send log by E-Mail”.

ayControl 3: 

In the room overview tap on the settings button in the lower left corner and a new window

will pop up. In the new window tap on the “Log” option in the list and the log window will appear displaying all the log data. In the upper right corner of the log window tap on the email icon.

Please describe the problem shortly in the email and send it – our support team is already listed as the receiver of the email.

How does the EIB/KNX bus control over a network work?

The KNX standard defines the method of sending the packets over the network. This method is called „KNXnet/IP“. Programs on all devices that can be connected with a network (smartphones, tablets, PCs, netbooks…) are able to communicate with a bus. ayControl implements this standard and is therefore compatible with all of the KNXnet/IP products.

How can I extend an existing EIB/KNX bus system with the ayControl?

ayControl can be integrated into an existing EIB/KNX system any time.
ayControl is the mobile extension for the installed wall panels and therefore offers a comfortable upgrade of your EIB/KNX bus system.
With the ayControl you can experience all the advantages of an EIB/KNX controlled home con a completely new, mobile level. The comfort you enjoyed before is now brought to a higher level since now you can move around your house/office while controlling the KNX system.

What is the iseo Designer 2?

iseo Designer 2 is a previous ayControl configuration software for the ayControl versions 2.1 and lower.
