Overview
A KNX controller for boards with little room. The LogicMachine5 Lite Power (LM5Lp2) is the narrowest LogicMachine5 KNX model (3 DIN; the others are 4 or 6 DIN). It has no DALI, 1-Wire, CAN FT or on-board analog/digital I/O, so the work it takes on is software: Lua scripts, schedules, scenes and protocol conversion.
- Three modules wide. One KNX/TP line and one RJ45 port, powered with 24 V DC from the terminals or via passive PoE. It fits boards where the 4 and 6 DIN models do not.
- Serial ports for Modbus. Use the RS-485 port for Modbus RTU devices, and switch the second port between RS-485 and RS-232 in software as the project needs. BACnet/IP server and Modbus RTU/TCP master are built in; Modbus slave and BACnet client use the vendor's script libraries.
- Schedules that follow the sun. Events run at a set time, at sunrise or at sunset for the site's coordinates, with holiday rules. Facility staff can edit them in the user interface, without the admin tool.
- Visualisation, Apple Home and Google Home. Web visualisation for PCs, wall screens and mobile devices, locally and remotely. Apple Home runs through an app on the controller and a QR code; Google Home goes through the vendor's LM Cloud and needs an internet connection.
- Secured, and usable offline. KNX Data Secure, KNX/IP secure routing and user-level permissions are listed in the datasheet. The controller is fully operational without internet access and sends no telemetry.
Where it fits in UAE projects
- A villa or apartment with one KNX line: sunset-driven lighting scenes, a thermostat routine written in Lua and a tablet visualisation for the owner.
- A small office or retail unit where an RS-485 meter or an air-conditioning gateway has to reach the KNX line. The vendor publishes an integration example for CoolMasterNet VRF gateways over RS-232 or TCP (on/off, mode, setpoint, fan speed).
If the project later needs DALI or a CAN FT bus, step up to the LM5p2-DW1 with two DALI lines or the LM5p2-KC with CAN FT. The rest of the range is under LogicMachine.

Installation notes
- Ventilate or cool the panel in a UAE summer: the vendor's operating range ends at +45 °C.
- The vendor does not publish CPU, RAM or object limits for this model. Confirm them with the vendor before specifying a large project or a heavy visualisation.
