Hi everyone,
I'm using a KC868-A16, and I have an RF remote control that operates at 12V using a 12V battery.
My goal is to use the KC868-A16 to simulate a button press on the RF remote, so I can trigger it from Home Assistant.
I’ve opened the remote and soldered two wires to the button I want to control. I know that:

• The button is normally at 12V
  
• Pressing the button pulls it to GND
  

• Am I doing this the right way?
  
• where to connect the 2 wires on the KC868?
  
• Do I need to do anything else to ensure safety or reliability?
  

Is it possible to connect an analog sensor with a 4-20mA output to the KC868-A16? Some say only 0-5V and some say both. If so, how please? Thanks.

Hi
have the M30  V2.4.10
One clamp is in postive direction one in negative installed, but have always positive power at display.
I can not get negative power. What can this be?

First of im a newbie so please dont be hard on me. I purchased a B16M with Tuya it arrived yesterday. It came with no instructions but it seemed quite straight forward to connect up. Two terminals marked 12v I powered it up opened the Tuya app and hey presto it found it and installed it.

Once installed all the inputs and outputs were greyed out and no matter what I did. So I started hunting for instructions. Found the forum but couldnt post (but thats another story) found the ESP32 YAML File for home assistant installed that via ESPHome from my home assistant. That worked too but I was still unable to control the relays from HA even though the buttons moved on my HA nothing was happening on the board.

Now when I try to connect via usb the unit connects then disconnect connects then disconnect as if its drawing too much current and dropping out.

Ive since spoken via we chat and discovered there are some more 12v inputs (I suspect these drive the relays) connected these up but now I am just unable to connect to the unit.

Unfortunately Im at work now so unable to try any suggestions until this evening when I get home, but I would be grateful for any help that might point me in the right direction please. Ideally I need to get this back on Tuya.

Thanks Peter

Hi, I have the board in subject, with a newest firmware than the 1.0.19 (I test 2.2.2 - 2.2.10- 2.2.12) the "Input" page show only the two columns and i cannot associate te input to the output.

Can you please help me with this?

Thank you

I do repair and install electronics. I plan to expand my business to IoT. My first project is to create an automation system in my apartment.
KC868-A4 ESP32 seems  interesting for thd beginning.

I want to connect the temperature sensors ds18b20.
How many sensors can be connected to the S1 conector?
 Do I need to connect an additional resistor to the 4,7K?

Which inputs are best used to read pulses. (KC868-A  V1.6) 
For example, from a water sensor. 0-5V range? 
I think A1-A2 or S3-S4? 
How to correctly write a configuration for such an input?

Hi,

Can you tell me what type of antenna I would have to buy if I wanted to position one away from the G1?  Are all the three supplied antenna the same?

Thanks,
