Already have the Home assistant green connected and still setting up, but im torn between using the ZBT-2 antennae for zigbee or thread. The real question im here for is, If i buy 2 ZBT-2 anntenne, can i run both simultaniously? like one for thread, the other for zigbee. or is the limitation on the home assistant green not the antennae. thanks again!
