Josh Nano is mic only and doesn't have any speakers. It can hear you but can't reply (by voice) to you unless you pair it with the Josh Core which must be connected to your audio equipment. A typical setup is the Josh Core connected to a distributed multi-room audio system via audio matrix switch(s) and Josh Nanos in each room.Currently, I have a Micro in two rooms and plan to add a third one. I have no need for the Core as there is no legacy stuff to integrate or need audio I/o. I am just not sure what the use case is. My media room is getting finished, and want to make up my mind to go to another Micro or Core/One/Nano before starting the rack wiring.
Cheers
An alternative to this is the Sonos integration. Josh can be setup to use Sonos speakers to talk to you. You can route the audio from Josh Micros to Sonos speakers too.
You can do one of these three:
1- You can get another Josh Micro
2- You can get another Josh Micro and 3 Sonos One SL wireless speakers (one for each room with Josh Micro). The only benefit of this setup is louder and clearer audio replies from Josh through Sonos speakers. (plus Sonos audio apps).
3- If you have the following, you can get another Josh Nano and Josh Core.
3a- An audio matrix switch serving audio to multiple rooms including the rooms with Josh Micro and Nanos.
3b- Your audio matrix switch needs to be one from the Josh Ai integration list so it can switch inputs and outputs.
I am still not sure what Josh One is for.
