When I am trying to add the zigbee HZC Smart Dimmer (D688-ZG) to Homey it turns up as a unknown Zigbee device. I have installed/added the HZC app ([HZC electric App for Homey | Homey](https://homey.app/en-gb/app/com.hzc-electric/HZC-electric/)). As it is right now I can’t include the device in any flow or automation. Any one knows if the Smart Dimmer (D688-ZG) is not supported yet? Or have any contact details to the developer? Any suggestions on how to successfully add this device to Homey are welcome! ---

Is this still a problem? I just ordered a few of these smart dimmers yesterday, would be really sad if they don’t function as expected. ---

How did this go?
