I am building an off-road caravan and wish to use a simple smart switch to control the lights, etc. I found Kincony's Lesson 3 - Control relay by wall switch video on YouTube of a KC868-A4 receiving a momentary input switch that toggled the output relay on, a second momentary input toggled the relay off. It was perfect. I could have momentary switches in multiple locations to operate the same light (relay). I needed more relays, so ordered the larger A8 online.
I have zero experience with Arduino or ESP32, but I hoped to learn off the online examples. As part of that learning I discovered the A4 is different to the A8 through the addition of the PCF8574 to expand the I/O. I have managed to successfully upload the code from the Kincony - Arduino Lesson 19 on using the PCF8574, so I have the settings correct, I just can't find any code examples for making the A8 behave like the A4 example in lesson 3.
As a novice, could someone please point me in the right direction for the code to use a momentary press of a dry contact switch on an input to energise its corresponding relay, a second momentary contact on the same input to de-energise that relay again.
Obviously for all 8 inputs to control 8 relays. I would really appreciate it.

I have a Kincony KC868 A8 V3.1 board. After flashing the firmware and powering it on, the display shows "Kincony" and the yellow LED starts blinking. The board doesn't display the IP address. What's wrong with the board?

Hi Admin,

Is it possible to use LoRa for indoor connectivity?

Hello,

I'm trying to connect to two KC868-A16's yesterday. I have a MacBook Air M4, connected the devices with several cables, even tried to use two hubs to connect through USB, but the devices were not recognised. Then I tried a MacBook Air M1, then a raspberry pi 5, and finally borrowed a Windows 11 laptop. None of these devices recognised any connection to the usb port at all.
Even without USB, but connected to ethernet, the KC's didn't get an ip-address, nor was there a new AP I could wirelessly connect to (when I didn't attach the network cable).

The power light was on, I did push button 2 when connecting through USB (I also tried without).

Can I safely assume that both KC's are dead?

Thanks,
Hans

When using digital input in  IFTTT trigger action, what option do I select:
true, 
false,
rising edge, etc
to trigger the action?

How can I configure the Air quality sensor in TA? See picture

I am trying to configure my F16. But I came across your recommendation.  "4. It is recommended to use home assistant and Tuya mobile phone app at the same time. So that remote control by internet using Tuya app, local control by LAN using home assistant app"

Which installation approach will yield the recommended result?

I have here a faulty Kincony MB - I have wasted many hours reinstalling firmware at instruction of Kincony - there seems to be hardware issue with this board as it only reads from shunts 9 through 16 - no readings for shunts 1 through 8.

Please advise how to resolve this issue.

v2.2.17 improvement:
1. tuya app sensor data fixed by one decimal.
2. added new server location for tuya app.

Hi everyone,

I’m working on a setup with a Kincony KC868-A2 and a SIM7600 LTE module and I want to connect it to Home Assistant over LTE only.
At the moment I’m using Tuya Cloud, because it seems to be the only solution that officially supports LTE with this board.
My goal is to:

• Control the relays from Home Assistant
• Read inputs and sensor values (ADC, 1-Wire, etc.) remotely via LTE

Current situation:

• The device works fine in the Smart Life / Tuya app over LTE
  
• It also appears in my Tuya Developer account
  
• But in Home Assistant it shows as unsupported and I currently have no control at all
