I currently have a Duofern 2-channel actuator that I use to control two lights, and a Duofern dimmer. Both work through Home Assistant (HA) control. However, I have a problem: the 2-channel actuator has additional connections for two external switches, which I use for my regular light switches. When I use the external switch, the light is toggled, but HA doesn’t recognize this change and still thinks the light is off. Since I want to use both the external switches and HA control, I wanted to ask if you see any way to query the status and integrate it into HA. I would really appreciate your help.
