Coupling of wireless devices with the System Access Point

free@home wireless devices must first be coupled with the System Access Point before they
can be used in a project. The devices exchange a security key during the coupling process.
Communication between devices is carried out encrypted after coupling and they are firmly
connected with the System Access Point. Coupled devices cannot be connected with a different
System Access Point . They must first be reset to the factory settings.
Carry out the following steps to couple one or several devices with the system.
1. Install the free@home wireless device(s).
2. Use your smartphone, tablet or PC to call up the user interface of the System Access Point
that is ready for use.
3. Switch on the mains power supply of the free@home wireless devices.
The devices are now in programming mode for 30 minutes.
4. In the user interface of the System Access Point select "System settings" > "free@home-
Wireless" > "Search".
The System Access Point consecutively scans all free@home wireless devices. Devices
that are in programming mode are integrated automatically into the system. The scanning
process ends 10 minutes after the last device has been integrated.
Integrated devices are listed in the "Device list" of the user interface.
5. Use the serial numbers to check whether all installed devices have been found.
If a device has not been found, reset it to the factory settings and start a new scanning
process.
Possible reasons for not finding devices:
The device is not in programming mode.
■
The 30-minute programming time has expired.
■
The device has already been coupled with a different system.
