What’s the advantage of the zigbees? I can get both bulbs, wifi and zigbee for ~5 bucks.

I tried reading a lot of articles/ posts. This is all confusing. Some write zigbee is better with battery because wifi lamps need to stay connected with wifi. But the zigbee lamps need to stay connected with zigbee (however they communicate. must be waves as well) as well, does it consume less power? What’s the range of these hubs? Wifi is available everywhere. Do I need multiple hubs?

I want to connect them to home assistant, so arguments like zigbee can be better automated should fall short as well, right? I already have one wifi lamp which is automated enough for my taste. What shall I more automate than turn off at x and turn on at y.

And I haven’t even read properly into zwave or matter.

Any advice would be greatly appreciated!
