Loxone tree extension12/29/2023 ![]() The UART pin needed an external pull-up resistor to make it usable for normal io. ![]() Using the teensy's interior pins, and re-purposing one of the UART pins we were able to have 40 pins usable for io. We needed 4 pins for the ethernet connection & 1 pin for the on-board LED. It was a challenge to get 40 I/O available on the teensy 2.0. Each sub board has it's own 5v 5 port switch, and a POE splitter - the whole board being run by 1 port on my POE switch. In our build we have 2 sub-boards each with 4 nodes - making a total of 8 nodes with a capacity for 320 i/o. The boards have a web interface which is really important for setting up and diagnostics as you have feedback showing which inputs or outputs are active. The software and interface to the loxone does not use any polling at all- so all the double/triple clicks work flawlessly with the loxone system. ![]() I'm not a hardware expert at all! But the system we have made is bullet proof reliable. We did consider using I2C io extension boards, but physical size is a factor and it was easier for us to make it compact using the teensy. I chose the teensy 2.0++ as it had a large number of digital IO on the board. Add to that 20 door & window sensors, plus blind controls, PIR sensors, under floor heating actuators and pumps. We have 43 light switches - but each light switch has 4 contacts - making 172 inputs just for the light switches. When specifying the server, we quickly realised we would have to find another solution for all the digital io. Two Tree connections for up to 50 devices per Tree branch. 100 compatible with other Loxone products. Such a significant reduction in cabling will further ensure smart homes are accessible to all, opening up the market to new opportunities and boosting the growth of the industry.I've nearly completed building my own home, and have used the loxone mini-server to supply the home automation. The Tree Extension forms the basis for Loxone Tree technology and the integration of devices in the smart home or commercial building: Reduces cabling by up to 80. Thanks to the future-proof design of Loxone Tree, more devices can be added when required. Philipp Schuster, UK MD of Loxone commented: “Just like a tree, the needs of homeowners will grow and change over time. Die Tree Extension bildet die Grundlage für die neue Loxone Tree Technologie. With less wiring, installation time is dramatically reduced and configuration takes just minutes – a huge improvement from time typically spent on smart home wiring. The range currently includes a Motion Sensor, Valve Actuator and Touch Switch, with more products already in development. Loxone Tree allows for completely flexible wiring on a room-by-room basis.Įach Loxone Tree Extension has two ‘branches’ allowing for up to 50 smart devices to be connected to each branch. Loxone Tree is fully compatible with all other Loxone components and its open topology means that wiring can be tailored to meet the specific requirements of each project. The Tree Extension is priced at £87 and is part of a growing range of Tree accessories for intelligently controlling lighting, heating, security and more. Loxone, says it has has simplified smart home installations with Loxone Tree, a future-proofed wiring system that reduces up to 80% of the usual cables required to connect multiple smart home accessories to its intelligent Miniserver, the ‘brain’ of Loxone Smart Homes.
