Agreed. In its current state HA systems are too difficult for mainstream adoption and largely fail to offer a compelling reason for purchase and installation. Light switches and dumb sensors are still more reliable and simpler to use. My irrigation system is already programmable and has a rain sensor. My security system does what it was intended to do without fail.
I’m a gadget fan, so the novelty appeals to me - colored lights and all. My wife and guests just override the HA stuff, and the Sonos spouting weather reports only impresses me.
These companies have a tough sell ahead of them along with finding a sustainable business model.
