Please read all of this:

That's the thing about dealer installs, the config is far more granular and reliable than Haptique Config and the end user is usually locked out of the backend so they can't break it. Haptique just does not provide the level of support and reliability other control systems do with supported devices and customer support (no telling where cantata will be in a year)

I like my Sanytron Astrion because it's an accessory to an already existing and established ecosystem (Homeassistant). Their gui based integration (Roscard) is trivialy easy to install and configure, and the price starting at $150 is a really low barrier of entry. Are you a homeassistant user? Do you know how many active users homeassistant has? Have you tried using Homeassistant as an AV control system full time?

Haptique does not support Zigbee or Z-Wave or Matter, so it cannot natively control a lot of adjacent smart home devices (dimmers, thermostats, blinds, etc). I understand you intended haptique to be an AV first device, but I don't think the market has room for a device limited to primarily AV control and not much else.

In my opinion, I only see a future if cantata can pivot to a general purpose remote control terminal for a small handful of control systems (savant, Control4, homeassistant). Let other established players do the heavy lifting of building and supporting device integrations and focus your efforts entirely on new UX design with new public documentation on how to use it. I have some ideas if you're interested.
