Loxone Tree

Tree devices can be wired in almost any form: star, line, tree or daisy chain may be combined freely, only the ring is not permitted. As a result a Tree branch does not have to be routed back to a central point but can follow the actual path of the installation.

Loxone states that cabling effort can be reduced by up to 80 percent compared to classic star wiring. That is the core idea of Tree: fewer cables to the distribution board, more flexibility for expansion and modification.

Tree connects to the Miniserver via the Tree Extension. It provides two Tree branches, each of which can connect up to 50 Tree devices. The maximum cable length is up to 500 metres per branch.

The cabling uses Cat5 or better, alternatively the Loxone Tree Cable. Data and device power run together over the twisted pair, similar to how KNX TP combines bus and auxiliary power, but in the proprietary Loxone protocol.

Tree is a closed system: it only works with Loxone devices on a Loxone Miniserver, and there is no per-device addressing like the physical address in KNX. Devices are taught into Loxone Config and managed there as inputs and outputs.

Anyone importing an existing Loxone project into venfree finds the Tree structure again as part of the peripherals. Viewed neutrally, Tree is the Loxone counterpart to KNX Twisted Pair: same purpose, different technology and not an open standard.
