Smart devices management (Home, Home Assistant, philips hue, openHAB, ...)
Much like Google Assistant or Siri, ot would be nice if we could use vocal commands like "Turn off bedroom lights" or "Set living room lights to green" through a Philips Hue Bridge hub. Technically the app doesn't need to manually pair with Philips Hue Bridge itself, this can be done through a third party app like the Home App (by Dominik on F-Droid) and all Dicio would do is send commands to the Home App to do its changes. Obviously this would require some third party integration from the Home App though
Integrating http://openhab.org in some manner might be an easier, more maintainable, and more general solution to the problem of smart device management. I admit that I know little about management of such devices for I've none of them (yet!), but a framework for their disparate methods of interaction is probably best.
