HA systems like Control 4 and Crestron are very tightly controlled which is critical for them to be able to offer high reliability and end-user ease of use. Manufacturers have to write drivers between their product and each of the HA systems.
LIFX has not done that so they rely on drivers written by David Chow and while OK, they’re not great. In the HA environment it appears (to my limited understanding) that LIFX may also suffer from everything having to go through the cloud between C4 and lamps which creates a lot of lag. I assume if LIFX were to write their own driver they could eliminate that but I’m not sure.
HomeKit and similar options are still a long way from offering the control, reliability and ease of use of HA systems like C4. They may get there one day but I’m guessing that’s a long way off. OTOH, we’ve seen many people use use a HomePod or similar as an interface to C4 (and I’ve done it as well). While I prefer to simply push a button on the wall controller for a specific lighting scene, I can also say ‘hey siri, turn on scene cooking in the kitchen’.
