Zigbee is a communication protocol. The way your bulb reacts to a powercycle is up to a bulb. Mine remember last settings for example.

Rooster326@programming.dev 3 days agoDoes Zigbee have the same issues that other smart bulbs do with loss of Internet connection, and voltage drops/brown outs/black outs?
They all turn on the full brightness
4 AM my voltage drops from 120 to 110 - literally not even noticable and every light in my home turns on. Happened with Hue more than a few times and I got rid of every single bulb. I ain’t got sleep to lose.

Well zigbee has nothing to do with internet, the bulb just communicates locally to your hub. You can then connect that to your own local Homeassistant for example. What the bulb does with viltage drops is on the manufacturer I guess

No. They aren’t controlled via Internet (they can be, but it’s not vital). You have Zigbee switches that control them through radio. Or you control them with your Zigbee controller which is hooked up to your network, but works locally so even if your Internet is down it works on LAN.
Depends on the brand. Some do this. Most do out of the box but you can go into the settings of your Zigbee controller and disable that. I’d read reviews first.
Also Phillips Hue is actually a Zigbee bulb, which can be used with non-Hue Zigbee controllers. If I’m reading right this setting can be configured. community.hueessentials.com/t/…/720
