I recently bought a house that i’m renovating and i’m looking into the option to use domotics.
The electricity is wired in a star topology, so all switches and lights are returning to the main board.
I’m also planning to use 24V impulse switches.
Until now, I have a basic Openhab2 setup with a Rpi3, Razberry2 Z-Wave controller and a Fibaro dimmer switch.
This works greats but I also read that once you scale it up, it tends to fail sometimes. The radiation of all those components is also something that concerns me.
And since I will have all my wires in the main board, I would like a wired solution.
The needs at this point are dimming/switching lights and controlling blinds. And all of the components have to fit on a DIN rail.
I would also like the components to behave like the Fibaro switches. Meaning that when my RPI3 breaks, I still want to control everything manually.
From what I read KNX would be a great solution for this but is too expensive.
At this point I was looking at PLC’s and maybe DMX for lighting.
Are the things I want to do even possible with PLC ? And could someone explain me a bit how a basic setup would look like and what pros and cons there are ?
I also looked around for DMX but I can’t find any DIN modules for that. Ideally in that situation I would want “dumb” lights wired to a DMX DIN module that I can control.
But if dimming and switching is possible with PLC I would like to stick to that.
