KC868-A16S ESP32 16 Channel Relay Board Released - admin - 04-17-2023
We have designed KC868-A16S (ESP32 16 channel relay board) for home automation DIYer. it can easy integrate to home assistant by ESPHome. the hardware have 16CH relay (MAX AC250V 10A) output + 16CH digital input + 4CH analog input, support RS485 + Ethernet + WiFi + Bluetooth + 4G SIM7600 or 2G SIM800L GSM module + DS3231 RTC module + manual control button panel.

hi admin can we have more tutorial on kc868-a16s thank you
RE: KC868-A16S ESP32 16 Channel Relay Board Released - admin - 05-29-2023
A16S mainly use by ESPHome for home assistant. what software or function you want to use by A16S?

hello admin i have problems with the following code can you help me thanks in advance.
when I send the command the relays do not change state
#include "Arduino.h"
#include "PCF8574.h"

#include <WiFiClient.h>

Serial.begin(115200);

// You can remove the password parameter if you want the AP to be open.
WiFi.softAP(ssid, password);
IPAddress myIP = WiFi.softAPIP();
Serial.print("AP IP address: ");
Serial.println(myIP);
server.begin();
Serial.println("Server started");

Ok admin, yes I used this piece of code in my code but I'm having trouble getting it to work.
is there? a similar pc-kc868-h32b application for the a16s?
RE: KC868-A16S ESP32 16 Channel Relay Board Released - admin - 06-06-2023
do you means PC software for A16S? use in local network? we have a PC software for A16S. but use in local network.
