We have designed KC868-A128 ESP32 board use for huge INPUT and OUTPUT devices for home automation DIY. it is a input module based on ESP32 chip. it have 128 channel digital input ports, every input channel use optocoupler isolation, so that can work for 1000 meter with sensors or any dry contact devices. Support work with RS485. Made For ESPHome and easily integrate to home assistant for smart home automation project DIY. You can write any code by Arduino IDE to ESP32 wifi/bluetooth/ethernet RS485 module.

new pcb v1.5 of KC868-A8, replaced USB-C with MiniUSB port.

Hi.
I need code for KC868-A8 V1.4 For MQTT Use just like in KC868-4 mqtt code what is is useles because i2C and it has only WIFI.

Ineed
1. LAN Configuration with static ip and dhcp disabled with //
2.WIFI Configuration with static ip but not in use //
3.MQTT control lines i will edit subs and bups. inputs has to buplish and outputs has to subscribe
4. example how to make output control momentary or latching.
Can somebody help me . i have tried but i need code to learn and cant find eny clear code to read and understand.

Please tell me (if it possible) how to use rs 485 port with tasmota firmware?
I've got some rs 485 devices (such as C02 sensors, wind speed and so on) and want them to receive data from. Like i receive data from tasmota sensors to my mqtt server by json strings.

I have connected to rs 485 port some of them (powered on of cource) but no data came. like nothing happens.

Is it really possible with KC868-A16 or I must search some other device?

Thank you.

if you are using CM4 8G eMMC version, installed home assistant and add-on. when you have not enough space of eMMC, you can use "movedata disk" function, that can move your data to USB disk, save your eMMC space. it's easy.

actually esp32 will convert current signal to voltage from sensor. we have tested KC868-A4 board with current source, here are some photos from board and esphome log output:

Can you give me some code to measure water with dc current analog 4-20mA using ESPHOME?

I want to know the filter value representing the water level measurement as a percentage.

I am new to esphome.

new pcb v1.2 of KC868-A8S, added 4G SIM7600 module socket on the pcb.

Goodnight,

I have a led driver that uses the tuya/smart home platform, it is connected to alexa and works only by voice command, I wanted to use a digital input to change the state of the led driver from on to off, could anyone help me?
