Hello,

I have no success to read data from RS485 port (orange one). I use NODE-RED for building flows.

To make sure that it is not issue in any configuration I used USB->RS485 adapter and I had success to read data.

There are two serial available when execute

1. /dev/ttyS0
   
2. /dev/ttyAMA0
   

1. get the MQTT feedback message from every puch button.

2. create "automation" for buttons in home assistant.

Dear kincony Custmer support,
I bought 4 pieces of this module to connect them to varies function
1. External for learn the remote control of garage gate motor to open close by mobile app the same application for all.
2. Another to control reception 3 Air conditions remote control + home appliances of living room:-
DVD
VIDEO
OUTDOOR AMPLIFIER
PROJECTOR
HOME THEATER
SATELLITE RECIEVER
BLURAY
SMART TV
APPLE TV 

All in the same room and all work with remote control
Bearing in mind the 3 AC split AC are the same remote and code for all 3 unit and i need to control each separate from mobile app.
3. Master bedroom AC, TV, Satelite reciever, shutter motor using Wifi SONOFF
4. Multi purpose room Bluray 4 K, smart TV, XBox, home theater reciever.
Please send me clear procedures and you tube videos for installation and vsries programing related toeach function above..
Thanks in advance
Ahmed

I also noticed sometimes UART is disabled in kernel. The enable it you need to check in /boot/config.txt the line enable_uart

If it's set to 0 like follow

enable_uart=0
You need to change to 1 as follow

enable_uart=1
And reboot of course!

sudo raspi-config
   
make sure disable Linux UART console

Hi all,

i am pretty new to ESP32 and programming with Arduion IDE. I have purchased a KC868-A8-V1.4 board and now i wanted to do the Realy programming according to the instruction from your site KC868-A8 programming
Correct type of board is selected NodeMCU-32S and the pins in pins_arduino.h are changed to 4 + 5, PCF8574 library V2.3.1 from Renzo Mischianti is installed.
The problem i am facing is that the PCF8574 throws all the time "error" instead of "OK" and therefore the relays are not working.

In order to test whether the board has a hardware problem, I have also tried once the TASMATO accoring to the video Tasmato KC868-A8, this has worked without any problems. So the hardware is ok.

Do you know what i am doing wrong that the PCF8574 throws the error?

Any help would be appreaciated

Hello
I have also some problem to receive complete string (I'm ususing ararat synapse library in lazarus)
In your debug software works all ok and I check also with other program and all works correctly, I would know if the received string could contain some special Char because if I send this string   "5E0123C001000000000000000000000000000000000000000000000000000000000000000000000000000000FF" (to read digital input for example) I receiv only this
string   "5E0123C011000000000000000000000000000000000000000000000000000000000000000000000000000000FF"
while the correct (and complete) string should be this "5E0123C011000000000000000000000000000000000000000000000000000000000000000000000000000000FF00000000000000000101010001010101
I don't understand why I don't receive the last part of string (00000000000000000101010001010101)

thank you in advance
