Tree to Air Bridge

The Tree to Air Bridge is used to integrate various devices that are equipped with the Loxone Air wireless technology. It is connected via the Tree interface and features a compact design with integrated antenna. Due to the limitation of 50 devices per Tree branch, up to 49 Air devices can be paired to the Tree to Air Bridge.

It can be used, for example, in areas where the wireless range of an Air Base Extension is no longer sufficient, but where connection to a Tree Branch is possible.

The Tree to Air Bridge is installed in a suitable enclosure.

Connect the power supply and Tree communication wires.

For best signal performance, make sure that the device is not in close range of metal objects.

Then follow the pairing procedure

Pairing Air Devices

Up to 49 Air devices can be paired with a Tree to Air Bridge. Any additional Tree devices on the Tree branch in use reduce the number of possible Air devices. The maximum total number of Tree and Air devices including Tree to Air Bridge on one branch is always 50 devices.

Like the Air Base Extension, the Tree to Air Bridge does not work as a repeater. If Air devices are to communicate with the system via the Tree to Air Bridge, they must be paired with it.
