Hola es posisble conectarse con varios antenas o varios moviles ?

Funciona de coordinador zigbee y se conecta a los dispositivos de este tipo y a otros hubs zigbee de tu red. Debe estar conectado a un PC para gestionar los dispositivos.

is there a commitment that this is upgradeable to support the thread standard

That I do not know. Minus my Google Home Speakers, I don't have any THREAD devices and don't have any immediate or even potentially immediate plans/goals/interest to make the switch. Sorry that I can't be more help. - Chris
