we have designed KC868-E16P ESP32 home automation extend relay module. PCB with manual control buttons. it’s based on ESP32 , Ethernet POE + RS485 + 4CH analog input + 16CH digital input and 16CH digital output by 16A OMRON relay. Support ESPHome for home assistant and Tasmota firmware and "KCS: tuya app for home automation DIY.
 

Hi everyone,
I ask a silly thing: what maximum voltage can the 8 inputs (clean contacts) of the KC868-A8 board have? 12v? 220v?
The doubt arises from the fact that, when powered, with the tester, I measure 12v between the common and input 1 or input 2 or input 3 etc. etc.

Thanks
Pier

Hello. 
Anybody else having issues to read meter (KC868-Meter-1PV-RS485) data with KC868-COLB using Kincony Smart Board controller software?
Steps taken:
1. connected the Meter to COLB. Wire B to 12, wire A to 11
2. no other sensors or devices are connected to COLB, only the meter
3. successfully connected to COLB with Kincony SCB_V1.0.410.504
4. Enabled Autoreport
5. Opened the EMeter page
6. Set meter ID number
7. Clicked the Read button

After waiting about 1 minute all fields (kWH, V, A, kW, Q, Hz) are still 0.
Changed the meter to another one (replaced the meter ID in Kincony SCB_V1.0.410.504 ) but the result is the same. Cannot read meter data.

Any help will be appreciated. Thank you.

Can you please help me with MQTT setup for the KC868-A8S board? It's already configured but I still cannot operate from Home Assistant. I believe it UID issue.
Thank you.

we have designed KC868-AG Pro by ESP32 + Tuya + Zigbee 3.0 module, it's easy to use ESPHome for home assistant. Now you can use home assistant and Tuya app at the same time. You can define RF buttons and IR buttons to control TV or air conditioner by IR signal. KinCony AG Pro also is a Zigbee3.0 gateway.
 



There are different use way for KC868-AG Pro smart controller.

1. download "KCS" firmware to ESP32 chip. You can use IR receiver/sender, RF receiver/sender with ESP32.

2. config ESPHome work with home assistant, the config ymal file as same as KC868-AG's yaml file, you can download from KinCony's forum.

3. use Tuya mobile phone app directly, remote control IR and RF device by internet.

4. download Zigbee3.0 coordinator firmware to Zigbee module (from factory we have already downloaded), work as Zigbee3.0 gateway. it support tasmota zigbee, support work as ZHA in home assistant.

if you want to update Zigbee coordinator firmware for Zigbee module, you can use Jlink download by JTAG on PCB pins.

KC868-AG Por can connect with extend IR cable, just connect to "P9" green terminal on PCB. extend IR signal from Tuya module. if you want to extend IR signal from ESP32. just set the resistance RJ10 and RJ11 value.

RJ10=0 ohm RJ11=NC extend IR cable signal from Tuya module.
RJ10=NC RJ11=0 ohm extend IR cable signal from ESP32 module.

LED indicator and button:

on the bottom of box, there is RESET button for config Tuya module. HOLD on will reset Tuya module, then you can begin pair with your Tuya mobile phone app.

Red LED: power
Yellow LED: Tuya module state
Green LED: Zigbee state
