Connect Zigbee devices

Hey there,

I’m fairly new to the whole smart home world, so please be gentle if it’s a dumb question.

I’m currently on my way shopping all the devices I want for my new apartment.

I’m planning on running a home assistant/homebridge system to control everything through Apple HomeKit but don’t wanna be limited to Apple HomeKit products.

What I was wondering:

When I get the Aqara P1 motion sensor, do I still need a hub to connect it to Home Assistant?

Second question:

When I get a conbee II Zigbee hub, can I connect all my zigbee devices to it, or do I still need a Phillips hue hub etc.?

Looking forward for your tips!
