How to build a DALI+KNX light controller ?
In this concept we show, howto build a powerful light controller uning our own products.
What components do we need:
RESI-PS-65W-24V: 24Vdc power supply to power all components
RESI-SW-7G: Unmanaged Gigabit Ethernet Switch to connect the controller to the BMS system, but also to offer a programming connection locally in front of the switchboard cabinet.
RESI-T4-B: Raspberry Pi 4© based LINUX controller. Here runs our logic
RESI-DALI-PS: DALI power supply for the DALI bus system.
RESI-DALI-SIO: DALI 1.0/2.0 master gateway to access and communicate with all DALI components on the DALI bus.
RESI-KNX-PS: 160mA KNX power supply for the KNX bus system.
RESI-KNX-SIO: KNX gateway to access and communicate with all KNX devices.
Last but not least some RESI KNX sensors or push button devices or all other KNX products on the market. Of course we need also some DALI lamps.
No we can also put all this devices into a wall box. e.g. 36MU wall box:
How to handle more than 64 DALI lamps on one controller ?
We can add more DALI lines. In our sample 3 lines. Due to the fact, that we connected the DALI MODBUS gateways via RS485 we have to address every DLAI master gateway with an unique UnitID and you can use up to 256*64 DALI lamps with one controller.
Again we can put everything into a 36MU wall box:
Which software should we use?
We suggest to build this solution with either NodeRED or Node.js. But you can also use python or C++.
But you can use this also together with home assistant or OpenHAB to have a nice dashboard for your user interface. You can also use professional software like CODESYS or FIN framework to communicate with the components.
