Honeywell, Legrand, Haier, Xinhe Chuang, Schneider and control4, which smart home system is better integrated?

Honeywell's smart home is better in security and air conditioning, but it is more expensive. Xinhe Chuang is a little worse than them, but the price is much more affordable. In other respects, through infrared or radio frequency wireless communication, home functions are quite well integrated. Rogland has a great advantage in intelligent lighting, but other things are average, with strong overall power, but poor equipment control. Siemens, Schneider and ABB are almost the same, all following EIB bus. These three product lines are long and have great advantages in the panel, which is easy to unify the style with the whole home. Haier is pure deception. The advantages of Control4 are wireless Zigbee protocol communication and home theater control, but Zigbee protocol has not been widely used, and its stability needs to be verified. If the owner pursues stability, he can choose several EIB buses, and Siemens is also good. If the owner pursues a better intelligent experience, he can choose Honeywell, Control4 and Xinhe Chuang.
