KC868-E16T Tuya ESP32 Relay Module Released

[admin]

We have designed KC868-E16T with Tuya module and ESP32, the 8 channel removable relay board can work with ESPHome for home assistant, it also can use by Tuya mobile phone application for remote control by internet if you download firmware to ESP32. This board also is open source. you can download schematic diagram from KinCony's webpage and ardunio IDE demo source code for this board use by Tuya IoT platform.

How is the feedback for the switches, whether it is touch or momentary ?
how connection switches feedback ?  to know relay is on or off

[admin]

support use momentary switch type.
if you want switch LED to show relay state, you can feedback dc12v from every relay output to switch panel's "Dx" terminal, when relay1 is ON, 12v will feedback to switch panel's D1, so LED1 on the panel will be ON.

please draw how connect switches feedback led with out relay i see output relay 220vac how i connect it 12vdc

if relay is output ac220v, every channel output need a 12v small power supply for feedback dc12v to switch panel.

here is sample for E16T relay1 output diagram, ac220v-->dc12v feedback to wall switch panel's LED
   
there is also have a video tour about the relay state feedback to wall switch
