Hello!

I have a Kincony A6 V 1.4Sp motherboard.
I collect pulses from water meters on the Digital input and process them with domoticz.
These operate with reed sensors and there is noise in them.

Can I count on firmware that handles de-bounce? I would need a value of 1000ms.

Is there any input on the device in ESPeasy where a pulse counter can be recognized via GPIO?

Thank you!

Hello,
I am planning to use about 15 KC868-HA-V21 modules behind 6-gang momentary switches throughout my whole house and connect them to the KC868-AP dimmer board. The LED strips I am using are 24V.
Can I also use this 24V supply to power the KC868-HA-V21 modules? The documentation states that it is supported, but I want to make sure it is a safe and reliable choice. Or, would it be better to use a separate 12V power supply for the modules?
Thank you for your advice!

Hello,
is possible to use DM4 with ESPHome and Tuya ? B8M works fine, but DM4 has some trouble in tuya_wifi_mcu_light_output.cpp

Here is the log:

Hello,

I am planning a project based on the KC868-A16 v3.1 (REV:1.6) board. My peripheral types include 5V digital sensors (TTL/CMOS) and low-power 5V loads.

Could you please help me with the following technical questions:

1. LO0 and LO1 with 5V: The official documentation specifies 12V/24V for the LO0 and LO1 power supply. Is it safe and functionally possible to apply a 5V external voltage to these specific channels instead?
   
2. Onboard 5V VCC Usage for LO0 and LO1: Can I use the internal 5V VCC rail from the board to power the LO0 and LO1 loads? The total load current will be under 1A, which is within the XL1509-5 regulator capacity. Are there any internal limitations preventing this?
   
3. 16 Digital Inputs with 5V logic: How can I modify all 16 Digital Inputs (INPUT1 and INPUT2) to safely and accurately read active 5V digital signals (TTL/CMOS)? What is the exact hardware modification procedure for the PCB?
   

Here is sample, KinCony F24 connect with one TS RS485 sensor, you can connect with multi TS sensors.
   

for example:

set F24 RS485 protocol = "Modbus-RTU", baud rate= 9600bps. the RS485 address should be different with TS' RS485 address.
   

TS sensor default address is 1, so set in "SENSOR" webpage:
   
   

Then it will work in monitor webpage:
   

Hello!

Recently, I bought a KC868-A16v3.
Could you please confirm whether this schematic is valid for my KC868-A16v3?

Thank you in advance for your prompt reply.

Hello, 

Glad to join the forum, there are a lot of interesting things here.

I just received my Kincony A16v3 board equipped with the display. I planned to run it directly under ESPHome. 
I flashed my YAML file, but upon reboot, it wouldn't get an IP address. I finally found the issue: it worked when I placed it right next to the Wi-Fi router. 

At best, I get a signal at 2.4 meters away. It's as if the built-in antenna isn't working. Is this normal? 

What kind of performance/behavior are you experiencing?

Thanks for your answers!
