Quick verdict
The ZEN30 solves a real problem: you have one gang box controlling a light and a fan (or two lights), and you want independent smart control of both. The top is a dimmer, the bottom is an on/off relay. Both show up separately in Home Assistant. Practical and space-efficient.
Standout: Dimmer plus on/off relay in one gang box. Control a light and fan independently without taking up two switch spots.
