Greetings, Please advise as to what pins to use for a DHT22 Temp/Humidity sensor as well as an SCD40 Temp/Humidity/CO2 sensor.

Appreciated.

I find no infos how the SD card works.
Is it just to safe log files?
To read the log files I must remove the card or is there any other way to access the datas?

Hello,

I am building a new house and will like to create a smart system for all the lights and wall plugs in the house that includes many ESP32 sensors (humidity, temperature, magnetic, movement etc...) that could be used by home assistant in automation.
Also I am in a budget since there are many expanses with the new house and I will like to see if I can use the following setup:
1. Two KC868-A16v3 ESP32-S3 16 channel GPIO module that comunicate between eachother.
2. Each board will be used to controll a KC868-E16v2 relay board or a contactor. (Not sure which one will be the better option)
3. One board will be use for lights and the other board will be used for wall power outlets.
4  Also LEDs will be used in the house that need to be able to dim if needed.
5. I would like for the light switches to work also without HA but also to have a backup plan to make them work. (Ex to connect them also teleruptor so that it will work even if the A16 or A32 boards will be turned off or burned.)
6. Could perhaps A32 board be a better option for controlling the lights?


Can you please confirm if the board mentioned above are the correct ones or maybe could you please suggest a better architecture that I could use to design the the electrical grid of the house?

Really appreciate of help on this matter,
Erazer

Hi,
I try to use an analog input to trigger an output by IFTTT.
Doesnt work, I tryd all kinds of settings.
Monitor shows input when I put 3,3 Volts on analog input but I can not manage to get an output triggered

What do I wrong?
My goal is to get more than 16 inputs using the analog inputs for a switched voltage.

Hi,

I read that the A16 board requires 1,5A power supply.
However, what is the minimal power consumption of the board?

My requirements are implementable with the ESP32 in deep sleep mode most of the time.
It would be good to implement high availability.
So, for the ESP32, I could implement a USV with a small lithium battery.
How about the periphery?
How much power does it need?
Is it possible to switch of the periphery (I/O pins, USB port, Network)via software? 

Thank you

Can I use the product for this use case:

- recieve RS232 signals from external source for open/close of the relay
- attach OLED screen and configure display myself
- read signal from distance sensor (ultrasonic analog / laser digital)
- read temperature to adjust ultrasonic measurement (hot/cold air)
- send measurements to server via HTTPS over LAN

Hi all,

Thanks to join your forum.

I'm preparing a home installation based on HOME ASSISTANT using KC868 with rapsberry.

I need multiple power distribution boxes in different buildings based on :

One main power box ( with KC868)
3 remote connection power boxes. (with relays and analog input )

So, could you help me on which  communication hardware and protocol  I can use ? ( cables CAT 6 are dispached between each boxes.).

Hope my explaination are clear .

Great thanks

Daniel

The water level sensor is malfunctioning and has three terminals: two for 12 volts (one positive and one negative) and one for data. The new locally available sensor, however, has only two terminals: one for 12 volts positive and one for the data point. I will attach pictures for reference. My question is: should I connect the positive terminal to the 12-volt power source and the data terminal to the data point on the board? Is this the correct approach?

Does anybody know wich firmware I must use for the KC868-A16v3 Board?
I loaded   KCS_KC868_A16_V2.2.12.zip  with USB and now the board does not work anymore.
Was it the wrong firmware?

KinCony B16 ESP32 smart controller based on ESP32-S3-WROOM-1U (N16R8) wifi chip. Support 16 channel relay output, 7 channel 1-wire GPIOs, 4 channel ADS1115 16bit analog input ports. One SD card using SPI bus. B16 include DS3231 high precision RTC clock chip. LCD display will show wifi and ethernet IP address and Tuya connection state. B16 have I2C bus extender and RS485 port. You can write any code by Arduino IDE / MicroPython / ESP-IDF development tool to ESP32 module. We will supply Arduino / ESP-IDF demo code for different samples. Everyone can modify and change the code for your own smart home automation system project. it support use by ESPHome for home assistant or tasmota firmware for smart home automation DIY. B16 use KCS v3 firmware, it support home assistant auto discovery function by MQTT, so without write any config code (zero code) for home assistant. KCS v3 support KinCony cloud service (official shop customer free 2 years), remote monitor and control device by webpage in anywhere. KCS v3 support KinCony board integrate to Loxone Miniserver. Support Apple HomeKit for Siri.
