Are Zigbee hubs interoperable?

[old roost]

Hi there,
I'm a newbie with Home Assistant, migrated from Apple HomeKit a few months ago. When I was on Apple's ecosystem, I had bought Aqara M2 Hub to connect some of my Aqara stuffs that use Zigbee. It is connected to Home Assistant through the HomeKit integration.
But now, I'd like to add a new Zigbee device that is not sold by Aqara, and I don't know if I have to purchase a new hub. Is this hub interoperable with other brands?

You can always just give it a try and if it doesn't work, get a coordinator compatible with ZHA, so you can use your HA as a hub itself, rather than relying on the hub of some manufacturer who has a limited interest in supporting devices of third parties

thanks, is there a list of compatible hubs somewhere?

https://zigbee.blakadder.com/coordinators.html Is a list of good candidates

https://smlight.tech/product/slzb-06p7/ is a very popular option. The PoE makes it easy to optimize placement of the antenna

I'm personally using a DE Conbee III https://www.dresden-elektronik.de/index.php/produkt/conbee-3.html

and I also have a sonoff as backup and omnipresent threat to the other coordinator https://sonoff.tech/product/gateway-and-sensors/sonoff-zigbee-3-0-usb-dongle-plus-e/

Don't get too hung up on antenna size. As soon as you have a few non-battery devices, like outlets or light bulbs that are well distributed to form the "backbone" of your Zigbee mesh, the coordinator won't have to send anything over longer distances anymore anyways.
Different story if you're trying to connect multiple buildings into a single smart home though
