If anyone is interested, I created an addon and integration that work together to control Cync dimmer switches. I only have dimmer switches, but I think the addon should work with non-dimming switches and cync light bulbs as well, although I have never tested them. The integration creates a light entity for each room you have set up in your Cync app. The addon monitors the state of these switches and updates the HA state. I use Google Assistant text commands to control the light switches, so you will need to connect your Cync account to Google Home. I recommend creating a whole new google account for this purpose. Here’s a link to the integration and addon:
