If you ever need a language buddy, let me know.
There is also a Learn Dutch discord that is fairly active.
Duolingo sucks ass for learning languages. Dutchpod101 is pretty good, but the best is a combination of dutch books + listening like dhtchpod101 or some simple news podcasts or so.
KNX.
Everything is decentrally programmed, and you can do extra automations and stuff from home assistant, but KNX devices are wired (generally) and will always Just Work™. More expensive that the cheaper retrofit options, but if you factor in manual overrides or getting the “better” wireless smart devices it is comparable. They generally also have a manual override at the panel. For core functions like lights, HVAC, roll shutters or blinds, etc… That is honestly the best option (unless you want every light to be an RGB light for some reason, then you still need smart bulbs)
