Four further thoughts on Josh:
The game changer moment will be when Josh allows for room to room intercom, so one can call and speak back and forth with someone in another room utilizing the in room mic/speakers (same with door station).
They seem to be in the midst of a pricing structure shift, where licensing will be based on number of rooms total in your C4 project, not number of mics at play. So you get dinged for rooms you have no intent to control with voice and would never actually have a mic there to begin with (i.e. maybe wine room, master closet, hallway, etc). Pricing is going up on Jan. 1.
Crestron does have a more advanced integration into their touchscreens and remotes, but both require the user to button press. It's a question of if a future C4 Neeo "Gen.2" or T4 has the hardware capability to offer an always-on mic listening function for a wake-word.
At the moment it seems to me that Josh is a bit like pay radio. Certainly a luxury nice to have service, but the market won't bear their expected price point. SiriusXM I think started out by trying to charge $25+/month for service and now it's a fraction of that. It's tough to compete when competition is free (yes, even if Google/Amazon/Apple free comes at a cost of privacy, and reliability).
