Hello, how to wire( wire 0.5 ) a switch panel ? I use A4 with tasmota (...pin 36 39 27 14 ) k 1 k2 kcom to gnd d1 d2 d3 d4 of A4..thank you

yes, D1,D2,D3,D4 can use for switch buttons.

Good morning,
Let me explain better...I have its two-button switch.
Behind there are 5 contacts ( kc, k 1 k2 k3 k 4) and another 6 contacts ( dc gnd d1 d2 d3 d 4)... how should I connect these with the contacts d1 d2 d3 d4 of the kc868-A4?.. how and how many threads...thank you

let your ESP32 board relay output DC12v, then connect to your switch panel's D1,D2,D3,D4 , LED on switch panel will be ON/OFF by dc12v or 0V. which electronic level will ON, suggest you have a test, i am not see your switch panel photo, so i can't sure.

Thanks for the reply...I attach a copy of the back of the kincony 2-way switch...I have to connect it to the kincony kc868-a4...switch has: 5 contacts ( kc, k 1 k2 k3 k 4) and another 6 contacts ( dc gnd d1 d2 d3 d 4)... as you can see from the photo above there is the gnd of the kc868-a4 connected to the k-com of the switch.. then there is the k1 red wire of the switch connected to the a4 d2 and d1 of the kc8687-a4...and the k2 yellow wire connected to d3 of the kc868-a4

A4---GND  ---->switch  KCOM
A4---D1-------> switch  K1
A4---D2------->switch  k2
A4---D3------->switch  k3
A4---D4------->switch  k4


Ignore the switch D1 D2 D3 D4 GND and DC

Very good..now it works. Thank you, Have a nice day.
