How can I power multiple devices simultaneously using KC868-A16?

KC868-A16 OUTPUT 12v to relay's coin, make sure your relay's coin another point is GND.

Thank you! After connecting the two GND wires to one of the input GND terminals, I can get it working now, but it's a bit backwards... When the Relay switch is ON, the output switch in home assistant is OFF, and vice-versa.  How can I change this so that when I switch on the output using esphome in home assistant, then the relay switch LED also turns on?

In the picture here, you can see that both relay switch LEDs are ON, but at the same time my corresponding output switches that link to these relays in home assistant esphome are OFF.

add "inverted: true" to your OUTPUT in yaml.
