Hello everyone. According to schematics of KC868-A16, P-MOSFETS are used in DO circuits. Is there any
a)  KC868-A16 alternaatives with another schematics
b) possibility to orded specific boards whith N-MOSFETS schematics 
In all other aspects this board perfectly siuts my needs and I'm looking for opportnity to use it but the MOSFETS type in DO is extremly important in my case.

I have an e16t controller. Since the purchase, I have been using tuya (factory firmware). I recently decided to try a smart home based on the Home assistant. The Home assistant is installed on Raspberry pi5.
I found a post on the forum that you can install a new configuration file on the e16t (via esphome), which will allow you to control the relay via tuya and home assistant.
I did everything according to the scheme, and I ran into such a problem that esphome does not see the connected e16t device via usb. I used the cable from the e16t kit, I also tried to use another cable, but with no result.

After that I tried to connect e16t to PC (windows), but PC cannot detect e16t. The driver for the ch340c is installed.
Nothing happens when connected to a PC.

Can you tell me how to solve this problem?

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?

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.
