Loxone Tree vs Air: choosing your wiring topology
Tree and Air are two ways to connect Loxone devices to the same Miniserver — one wired, one wireless. Here's how to decide, and when to mix both.
How to choose per project
Map the building phase
New build or renovation with open walls favors Tree; a finished retrofit favors Air.
Plan the Tree branches
Tree runs as a branching structure from the Miniserver, not a star like KNX — plan cable runs accordingly.
Identify hard-to-wire points
Use Air for sensors and switches where pulling a new cable isn't practical.
Mix on one Miniserver
Tree and Air devices run together on the same Miniserver — combine them per room as needed.
Tree vs Air at a glance
Power + data together
Tree's 4-wire cable carries both power and data to every device on the branch.
Tree: single 4-wire cable
One cable feeds power and data to Tree devices in a branching (not star) topology from the Miniserver.
Air: battery wireless
Air sensors and switches pair wirelessly and run on batteries — no cabling to pull.
Best fit by scenario
Tree suits new builds and open-wall renovations; Air suits finished retrofits and hard-to-reach points.
Local logic on the Miniserver
All automation logic runs locally on the Miniserver, without depending on the cloud for core functions.
Configured in Loxone Config
Both Tree and Air devices are set up in Loxone Config, the free PC tool with visual function-block programming.

Frequently asked questions
What's the difference between Loxone Tree and Air?
Tree is a wired bus: one 4-wire cable carries power and data to devices in a branching topology from the Miniserver. Air is a wireless, battery-powered product line for sensors and switches, paired without any cabling.
Can I use Tree and Air on the same Miniserver?
Yes. Tree and Air are both connected to and managed by the same Miniserver, so you can mix wired and wireless devices room by room based on what each point needs.
Is Loxone Tree wired in a star or a tree topology?
Tree, not star — the cable branches out from the Miniserver like a tree structure, unlike KNX, which follows its own topology rules.
When should I choose Air instead of Tree?
Air fits finished spaces and renovations where pulling a new cable isn't practical — it's the wireless, battery-powered option for sensors and switches at hard-to-wire points.
How is a Loxone system configured?
With Loxone Config, a free PC program for visual programming using function blocks — used to set up both Tree and Air devices connected to the Miniserver.
