I have a smart home and it works great, but it all runs locally. ZigBee for most devices, because it is an encrypted local mesh communication protocol. The things that use wifi have no internet connection. Home Assistant is open source and runs everything locally. If a vendor of any products doesn't support their ZigBee hub anymore I don't care. Home Assistant is my ZigBee Hub. If any cloud service is shut off I don't care, because nothing is in the cloud. If you build new KNX is great. It works with Home Assistant and it's just a bus system. You program it once and it works for decades.
