Reliable Zigbee communication depends on a strong Zigbee network.
If you only have a limited number of battery powered Zigbee devices that are within direct reach (a few meters) of your Homey, then that should work.
If those devices are spread throughout your home and need to overcome greater distances or obstacles (like walls), then you would typically need to add mains powered devices (like a smart plug or smart bulb), that act as Zigbee routers. They extend the Zigbee network and allow other Zigbee devices to communicate to Homey through them.

If the bulbs are connected to the Hue hub, then that hub uses a separate Zigbee network that cannot be merged with Homey’s Zigbee network. Connecting those bulbs directly with Homey would indeed extend Homey’s Zigbee network (assuming those bulbs are router devices).
I am not a Hue user myself, so I don’t know if you would lose functionality. You would need to switch to the Hue community app: Philips Hue, without the bridge | Homey which would normally offer the most functionality compared to adding the bulbs as a generic Zigbee device (the other option)
Note that pair devices to Homey can only be done one at a time. You cannot add a whole group of bulbs in one go.
There are separate topics on this forum for Aqara devices as well as for the FP300 sensor. You might want to check those out.
