In the Best Buy guide it states “You can group Nexa Smoke Alarms into a network of up to twelve devices, creating a mesh of sensors that all activate when one detects smoke. The great thing about this Nexa sensor setup is that the device closest to the smoke will emit a different siren sound, helping you quickly locate the fire or smoke source.”  
I have 3 devices. Can anyone tell me how to set them up in a mesh network? Do you simply pair each one with Homey? Or is there something else which needs to be done?
