i am using kc868-a64 board controlling for lights and  smoke detectors. i also have 1 separate esp32 dev board which is controlling my ac through IR and ld2410 sensor for presence detection. 

kc868-a64 communicating through  Rj-45 and esp32 dev communicating through wifi they both working really nice under home assistant, 

now i want to connect kc868-a64 and esp32 through rs-485 for sending my IR data and getting ld2410 readings from esp32 dev kit to home assistant. how to send ir data and receive sensors reading    through rs-485 from esp32 dev kit to kc868-a64

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.
