I don't have hands on experience, but I read about it a lot. Yes, it is not meant for DIY, but in Germany there is a big DIY community, unfortunately that also means a lot of hands-on experience is shared in German forums and Youtube channels. The main issue is the ETS software you need to configure KNX devices. Full license is around 2k€, but if you have up to 15 KNX devices I believe there is a cheaper license. Next apartment/house i buy will probably be wired with KNX for roller shutters, heating/air conditioning and for lighting either KNX or KNX-Dali Gateway. There is an interesting channel on Youtube if you are interested: https://www.youtube.com/channel/UCnGAZMA4wzOYx_P7aXTRc7A https://www.youtube.com/channel/UCnGAZMA4wzOYx_P7aXTRc7A
