Hi,
The I2C conector on the KC868-6 has a 3.3v pin for power. I have a PN532 RFID reader that I want to connect to the I2C bus, however the PN532 needs 5 volts. Can an I2C device with 5V logic level be connected safely to the I2C bus?
Thanks in advance for your answer.

Could you let me get a sample ESPHome yaml file to obtain sensor data from DS18B20 and ADC 1 ~ 4?

My board is KC868-A4 Rev. is 1.2.4

Hello Kincony Team,
My name is Bart, and I am currently in the exciting process of building my new home. I am very interested in integrating smart home technology throughout and am seriously considering Kincony as the primary manufacturer for these devices, with a particular focus on wired Ethernet-connected devices, not Tuya.
As I am in the early stages of designing the complete electronic and electric wiring from scratch, having the opportunity to test some of your products firsthand would be incredibly beneficial. My preference is to explore your wired Ethernet options for robust and reliable connectivity.
Based on the "Apply For Free Sample of KinCony Product" page, I would like to request a sample to evaluate. While my current situation doesn't perfectly align with the listed conditions, I believe it could potentially fall under category B - "Start a Project." My project is the complete smart integration of my new home, and testing your wired Ethernet devices would be a crucial first step in this endeavor. I plan to thoroughly document my integration process and potentially share my experiences with the wider community as my project progresses, focusing on the benefits and implementation of a wired smart home system.
Would it be possible to receive a sample of a wired Ethernet-connected Kincony product suitable for smart home integration for testing in this context? I am particularly interested in exploring devices that do not rely on the Tuya platform.
Thank you for considering my request. I look forward to hearing from you.
Sincerely,
Bart

Hello everyone,

Could you please let us know when the T64M and T128M will be released?
Thank you for your feedback.
Have a great day.

   
Hi. I have bought your A16v3 and install your KCSv3 on it. I am making a Door entrance and alarm system for my shop/house using your A16v3 board with Home Assistant. For now I test with one door and one buzzer, later I add more door window sensor.

I am trying two different digital output setting for one buzzer. Meaning I connect two digital output wire to one buzzer as shown in picture above.

I use DO1 for alarm sound. When night time and shop is closed, if someone open the door, the buzzer will turn on continuous.

I use DO2 for notification beep sound during the day, when shop is opened and customer open the door it will play a short beep. Because I want a short beep, i set it to delay with 3x100ms.

When I connect the board as shown in picture above, the KCSv3 become buggy. It become slow to load, freeze or crash and not responding to click. And when it on the buzzer in IFTT or Home Assistant automation, it doesn't follow my setting as above, it just on for two or three seconds then it off. I have to factory reset the board to make it ok again. If I connect only one digital output to my buzzer, it work OK. 

So does this mean I cannot connect two digital output to one load? I have to use two or more buzzer and connect separately for each different type of programming?

In A16v3, can I use usb type-c to Rj45 adapter to connect Ethernet cable?

I am planning to use the a32 pro for a project 
But before buying the board is there a cheaper version with less io that I can use to test if the board is something for us to work with.   So same functionality as the a32 pro but less io

Hello,

I recently bought KC868-A16 unit and just installed that in my electric box. I supplied 12V, connected the USB cable and tried to program it with ESPHOME firmware.

The problem I'm facing is that the unit is not showing up as COM port in Windows. Steps I took to enter the programming mode I guess should be:
1. connect USB-C to the computer
2. press and hold S2
3. connect 12V power

This should make the unit switching to upload, shouldn't it?

I tried also alternative path. I connected the unit through ethernet (on WiFi there is no custom KC868-like network so I guess maybe through ethernet it should work). The unit got assigned an IP address (checked it on the router) and can be pinged properly.

When trying to open http://units-ip/ page nothing shows up. I also guess there should be some standard firmware UI accessible under this address, shouldn't it?

How do I proceed? Please support.

I am really new to working with ESP32.
My goal is to use the device to count Pulse from electricity meters.

I understand ESP has a pulse counter sensor 
https://esphome.io/components/sensor/pulse_counter.html

Quote:On the ESP32, this sensor is even highly accurate because it’s using the hardware pulse counter peripheral on the ESP32. However, due to the use of the pulse counter peripheral, a maximum of 8 channels can be used!
