Eh not really if you’re actually using mesh networked smart home devices that run on zigbee/thread/wave/matter or whatever you’re using some kind of controller with one of those radios in it. Using your phone as the only controller basically means you’d only be able to control/talk to those devices when your phone is on and at home, so forget any kind of automations if you’re not around. If you already have a controller, it’s most certainly networked so having a matter radio in your phone is basically pointless.
