Hi guys,

I just got an A16 board. I read the design review (https://www.kincony.com/esp32-board-16-c...dware.html) but I didn't really find any proper solution to connect RX / TX UART TTL pins to the board (for my R503 fingerprint sensor). 

Could someone please help me how to connect that sensor / use UART with that board?

Thanks and best regards!
Stefan

I just purchased KC868-A6V3 Board.
On connecting the unit I tried connecting using wifi hotspot.
I did not find the hotspot I was expecting instead a "Hidden network" appeared in Wifi network list.
I was unable to connect to this 
I thought that perhaps unit had shipped unconfigured as I purchased from Aliexpress.
I then tried flashing using KCS_A6V3__v3.19.0 firmware but got the same result.
Firmware tool indicated successful installation.
I then tried setting up using ESPhome in HA using your supplied YAML file and that worked OK , unit comes online  , relays are able to be used.
I tried again using KCS firmware but still same result and Hidden network appeared again in Wifi list.
I tried connecting using SSID of ALR-0070077FE024 and passkey supplied in ESPhome YAML file which got me to the message "unable to connect to this network"
I then went back to ESPhome configuration and it works again and appears online , relays work
This proves that the hardware works but I really want to use the Lora functionality to control some water controllers I have.
Also the LCD display has never displayed anything , - why
Any assistance you can supply is much appreciated

Hi, as i wrote previously in another thread i'm quite new on this modules so sorry if i write something already discussed.
I'm recently facing the need to update the firmware of my B16s because i see new feature that i want to try. The problem is that i'm not finding any way to preserve the configuration (Network settings, IFTTT settings, custom Protocols and so on) so i could be able to load the new firmware but don't spend too much time reconfiguring manually all the stuffs.

Is there something i'm missing to backup the module configurations?

Thanks in advance.
Kind regards

New user here!  I have not yet purchased the ALR, but am looking at purchasing for several remote sensors and the gateway.  In reviewing the documentation and the youtube videos, it seems the individual pins are pre-defined sensors like the DHT.  Is there a way to create a custom analog and/or digital sensor on the ALR?  For example, if I have a High/Low signal?

I am teaching Embedded Systems and IoT courses in Electrical Engineering and Computer Science at the Polytechnic Institute of Bragança, Portugal. It would be interesting to include Kincony products in the course curriculum. Students usually apply the products used in academia in future developments of their professional careers. 
Thank you.

Since I installed Esp home on my kc868-a16v3, I can't access anymore by using kincony http://192.168.1.200  http://192.168.1.4,  http://192.168.1.225,...
I can only use Homeassistant to manage it.

Please can I ask you some help to find the way to have esphome folder on kincony ?

This is the acual acces to kincony I have by HA

Hello,

I have C868-A6 and KC868-HAv2 module,
with the latest Kincony firmware, but I can't find on IFTTT tab how to set action with MODBUS-HA protocol.
It possible to setup with this configuration?

Digital inputs works well.

Hi I am from the Philippines, I have purchased the SIM7600E 4G+GPS module and I am having some trouble with the module because it is stuck with the LED being turned on. I am using a sim card that is 5G with 4G fallback since as of the moment I don't have any access to a old 4G sim card.

I have watched the Kincony youtube video on how to properly insert the sim card and also installed all the necessary drivers needed for the uart tool. How do I fix this?

Hi,

On the KC868-A6 board, there are no directly accessible GPIOs like on the KC868-A6 v3.
Is it possible to reuse or repurpose some GPIOs without soldering or desoldering components?
I was considering IO13 from the internal serial port (P17 interface), but I’m unsure because the CPU schematic shows IO13 as not connected (marked with a red cross).
Are there any other GPIOs that might be available?

Thanks in advance for your help.
