Hello

I have a 32 channel relay board to control the blinds on the house. Is it possible to set the relay to turn off after a certain time (1 minute)?

KC868-A4 smart controller , many hareware resource for you to use, you can write any code by Arduino IDE to ESP32 wifi/bluetooth module. We will supply demo code for different samples. Everyone can modify and change the code for your own smart home automation system project.

Here is resource list:
WiFi/Bluetooth*1
RS232*1
Relay Output*4
Digital Input*4
433M Transmit PCB port*1
433M Receiver PCB port*1
IR receiver*1
IR sender*1
Analog input (DC0-5V)*2
Analog input (4-20mA)*2
Analog output(DC0-10V)*2
temperature and humidity sensor port*1
Buzzer*1

Hello. I have set up a small installation with the H16B + Domoticz on a Raspberry Pi3, it works well. I would like to know if there is the possibility to include COL B to have analog inputs and manage them under Domoticz. How can I do it?

Thank you.

improvement:
1: support KC868-D8 dimmer controller.
2: Optimized TCP connection performance.

you can update from Apple Store: "KBOX-smart home" application.

improvement:
1. home assistant or MQTT server reboot, relay and input state will auto update for HA recovery (when home asssitant startup after about 2 minutes).

download the ZIP file , unzip update the bin file for KC868-H32B relay controller by USB-RS232 cable.

firmware only for KC868-H32B, not for KC868-H32L

There will be firmware for Smart dimmer with MQTT

Home assistant switches work well via ethernet MQTT but do not restore their states after HA reboot (all stay off). Firmware version is H32B_V4.24.

Good afternoon, I use KC868-H32L. Will there be an update with the MQTT connection feature? Thank you in advance))))
