KNX or Loxone or Niko Home Control?
Niko Home control:
+ : easy setup, easiest domotics system, available through easykit
– : not flexible enough, stuck with niko products
Loxone :
= centralised
+ : free software with great UI (build by loxone), lots of documentation, integratable with knx , in my opinion the apple of domotics
– : expensive, stuck with loxone products
KNX (= EIB, European Installation Bus ):
= all devices (sensors and actuators) use the same transmission method and are able to exchange data via a common bus network
= decentralised , “intelligence” of the system is spread across all of its devices with their own microprocessor
+ : domotics standard , used by many knx-certified companies, in my opinion the linux of domotics, if one device fails the rest does not
– : less documentation, lot of programming required with ETS
Terminology
- system devices : power, programming UI, …
- sensor : detect events in building and send commands like push button, movement detectors, …
- actuator : convert commands into actions like lights, blinds, everything that consumes electricity…
- star topology : lights, blinds, everything that consumes electricity…
- PL : power line (230V)
- TP : twisted pair cable for data transfer (24V)
- RF : radio frequency
- IP : ethernet
- AC/DC : AC is data voltage, DC is supply voltage
- Line coupler (area coupler) : adds a new main line and divides in areas (1( lines max)
