Hello, I am new in this KNX system form and I would appreciate some helping hands. We got KNX installed and programmed in our house. Normally I am always get myself involved in the construction etc but I realized that with KNX I am depending on the electrician and his program to do any changes or adding new lights. This is not quite what we had in mind and in case he will win the lottery and move to an Island far away I want to know what I can do to get control over my own system. I saw that you can by KNX programs and I presume they help me with programming and controlling my KNX system. In our case it is all programmed already so my question is; ,, do I need any project file on USB from my electrician to be able to manipulad the KNX''? And which program do I need to buy to be able to program our KNX by myself? Thanks in advance for any help.
