My experience has been different. My Sylvania Zigbee bulbs, if they don't pair perfectly out of the box, require a reset-and-re-pair process that I usually have to go through three or four times per bulb. Also, try pairing 4 bulbs on the same switch at once... you'll be lucky to get two to join. Or, try running an automation that sends more than 4 individual state updates to the Zigbee network at once... one or two lights will change. Most of the smart home apps (whether you're using the Hue app or SmartThings or whatever) need a cloud connection for some ridiculous reason to control the lights; and suffer from a chronic case of not knowing the current state of the lights. All in all, it comes across as very immature technology. It's as unreliable compared to WiFi as WiFi is compared to Ethernet.
