Trying to find a way to connect and control Atomi Smart lights

I have the Atomi Smart Wall Sconces and the String lights, all connected to the Atomi Smart App.
From my understanding there is no viable integration with Homeassistant … at least not yet.
So I am wondering what the best way would be to get them connected to Homeassistant.

Since the Atomi Smart app is integrated with Google Assistant and Alexa, I am wondering, if I can set up a routine in Homeassistant to call Google or Alexa to drive the lights (brightness, color, on and off, etc) for each of the lamp groups. Right now they are controlled with a Zwave dimmer, which does not do anything but turning on and off.

Thanks for some ideas
