Greetings from KNX n00b, but experienced system engineer, linux enthusiast…
Let me summarise my question as short as possible:
Recently I purchased “smart home” apartment which is 7 years old, I can see 3 KNX related modules in the electrical cabinet: Merten instabus EIB universal dimmer REG-K/4x230/250W, switch actuator REG-K/8x230/10 with man.mode and power supply 160mA.
(houses in this community come with some sort of central server device as GIRA or similar, and control the home via tablet, but apartments do not have it)
I was thinking of low cost solution such as KNX USB interface with raspberry pi with openHAB, knxd for binding.
Is it possible to connect knx usb device to this existing KNX components (mentioned above)?
Now, I would manage to setup these components, but then what? Since I don’t have any documentation, don’t know any physical address…how to configure knx.things and other files…
The apartment has 10 wall units to control AC + lights.
3 of them have screen to control AC temperature, set Auto mode, read the current room temperature + lights and dimmer.
7 of them are just light control.
What do you recommend, what is your opinion, should I try to locate the company that did the KNX installation or is there any hope for DIY project in this situation?
thanks in advance!
