I've purchased a KC868-A32 module and its functionallity is as expected.

I try to implement an I2C communication between the KC868-A32 module and an arduino device in order to control PWD IOs of the arduino through the KC868-A32 module (i.e. through Home assistant).

Could you please provide some instructions or an example on the code for the arduino device?

Thank you in advance

Good morning everyone,
I'll start by saying that I'm completely ignorant of esp32 and it's my first experience. I have home hassistant on raspberry and I would like to show the sensors I have on the French windows.
I have 8 sensors, 2 PIRs, 2 sirens, 1 inserter, 1 keypad, 1 armored door sensor all wired. I also have 5 radio sensors and 2 radio pirs. Is the KC868-A16 model ok? Does anyone have a guide on how I can connect and configure everything to see all the various sensors on the home assistant?

Hello Kincony,

I would suggest to do something with the forum configuration. It is getting useless with the thousands of deleted spam threads and in between one or two normal forum topic.
It is getting really difficult to find and read the valuable information in the forum.

You just need to put some control to prevent spambots.

Some suggestions:
- Captcha, reCAPTCHA, Hidden captcha, etc..
- Moderate first post for each user.
- complex registration questions
- new users manual activation

Anyone any other ideas?

Is there any plan to do something against these spammers?

thanks

Hi Kincony,
I hope you are well.

I have recently purchased the KC868-A2 via AliExpress.
This is a great device with ethernet and RS485. It is a very fine unit. It joins my KC868-A4 and KC868-A8 in my systems.

This unit was purchased to interface with ModBus water meters at a remote site.
This has been progressing well until I had a problem making the RS485 work.

The board is KC868-A2-V2.4. I notice this is slightly different to the circuit diagram on the website which is made for V2.3. I am not sure if this is part of my problem as I might be testing incorrect pins?

My issue is I cannot see RS485 waveforms at the output.
In my fault finding I traced back and looked at the signal at several points:
1. P6 9H connector on the "A and B" points. No signal during transmit.
2. I checked the output of MAX13487ELSA (pin 6 and pin 7) to find no output during transmit.
3. The output of the ESP32 Pin 8 shows the ModBus command (Siglent Storage Oscilloscope).
4. I checked input of  MAX13487ELSA (pin 4 to gnd)  to see the RS485 signal coming from the ESP32 Pin 8. It is good level. The ESP32 is running latest version Tasmota 14.1.0 and the UI confirms that the ModBus signals are working (this I think means the code is correct).

I see that the Pin 2 and pin 3 of the MAX13487 are held high (measures 5.2V) and so the device should present data on the RS485 oututs Pin6 and 5. There is no signal at A &B on P6 during transmit.

Do you have anysuggestions as to what is happening? 
I am doing something incorrect or is there possibly a fault?

Many thanks for any assistance you can provide.

Hi.
I want to activate the 16-channel remote control and it is necessary to configure the buttons on the remote control as well as the settings for RF. 
The controller is linked to HOME Assistant.
I defined the RF channels in the YAML file, but I can't find where I can map the buttons of the remote.
I also don't find that the HOME ASSISTANT recognizes the remote.
Thanks for the help.

Where can I find the examples that are promised? The examples with the KC868 Arduino library do not show how to use the network port or the rf433 connections.

I mean these:

   

Hello, I bought a KC868-A8, but in my excitement I ended up connecting it directly to the USB and cell phone charger. It is visible via USB but does not record anything. At startup, it does not test the relays, it just flashes the lights quickly, but the pilot light works. I've already replaced the IC CH340C, tested the components in the USB and 12v input circuits but I can't find out what else could have burned out. I would be grateful if someone could help me. Thanks.

Hi,

I have a few issues:

1. When I install firmware versions newer than v.1.0.24, I can't set Bind Output, Function, On, Off and Toggle in the input settings. It simply doesn't exist (screenshot 1). This is v.2.2.4 (screenshot 2). In older firmware versions, this problem does not occur (screenshot 3). This is v.1.0.24 (screenshot 4). I'm not sure if this is an issue on my end or if these functions have been removed?
   
2. Will the I2C sensor support function be added in future firmware updates? I prefer the official firmware over ESPHome, and I would like to be able to connect and operate the BME280 sensor with the official firmware just like the ONEWire DS18B20 sensor (in newer firmware versions).
   
3. Is it possible to create a "virtual" button? I'm thinking of a situation like this: In my office, I have a main light connected to the output on the KC868-A16 (the button controlling this light is connected to the input) and an LED strip connected to Home Assistant via Zigbee communication. I would like to toggle the main light with a single click, toggle the LED strip with a double click, and turn off both lights with a hold on. Is this possible? It is possible to pull out the topic in Home Assistant to do automation on double click? Or maybe this can be done in the new firmware version, for example, in the input tab, where you specify which input will control which output, will be able to provide entities from Home Assistant?
   

Good Morning
I didn't find KC868-AI comunication protocol in "Software & Document" menù on your website, please, is it possible to see it;
Is this board has TCP server like KC868-H16B or KC868-COLB?
thank you
