I'm thinking of using either KC868-A16S or KC868-A8S to control 24V lights/devices in a campervan via ESP32 with momentary switches and via a smartphone. Both boards indicate they handle AC current. Can they also handle DC 12v and/or 24v loads with the built in relays? If so, what is the max amps per relay and in total? What is the make/model/part number of the relay switch used on the board?

They also indicate they use DC 12V to power the board. Can they use 24V power as well?

Hello,

I am trying trying to wire in a 3 wire, 12V pir motion detector.  

I have a brown wire to constant 12v source

I have a red wire ( trigger ) going to terminal for sensor #1

And I have the blue ground going to body and to ground terminal right next to terminal #1 as per legend on metal cover .

When I short ground terminal and terminal #1 I get a response but the pir is not working as expected.  Have tried other pir devices with no luck.

What is my problem here, has to be something very easy and I just can't get there because I don't know yet how to fine tune time, distance and LUX on the pir.

Picture of wiring at terminal attached .    

By the way, check out my project at YouTube video

I'm considering the KC868-AIO - I need several water level sensors and interested in using the 4-20mah version of this (as the accuracy is better over longer distances)
https://aliexpress.com/item/1005006338737673.html

It's a two-wire sensor, but I can't find any examples of how this should be connected to the KC868-AIO?  As these work best with 24V should the KC868-AIO be powered with 24V also?

good morning I tried to load the KCS 2.2.4 firmware on the KC868_A32 rev. 1.4 board. in programming I can't connect the input to the output (bind). in the input screen I only see "reverse". I also tried to load a previous version of KCS. I saw the video on YouTube but I couldn't solve it. I also tried with different browsers. can you help me?

Hi,

running the AG PRO with the latest firmware.

1. IR Learning - KCS
If I put the firmware to learning via KCS Web frontend, the Samsung TV IR signals are not recorded. Even no beep is played.
If I use Tuya the IR is recorded.

2. IR Learining - Node Red
In addition I found a video on youtube where the Inject node was used to put IR in learning.
Now I checked the HTTP and the MQTT protocoll. There is no explanation on these protocols how to do this.

3. MQTT Problems
I enabled the MQTT to a remote MQTT server.
Using the MQTT-Explorer I can see the Topic with STATE created. So, apparently AG and MQTT server connection is ok.

BUT: STATE is always empty! Also when I send  {"get _datas" : {"value": true}} -  nothing is responded.

I was planning to use my A16 to form a security system, and while door sensors are easy enough, I'm just a touched confused over how to connect alarms, buzzers, and a motion detector...

A four-wire motion detector needs two of it's wires to be connected to a 12v power supply (I think?) and it's two alarm wires can be connected directly to one of the dry digital inputs.

I believe that I'll then need to connect the siren and alarm to the mosfet outputs via two relays, which will then also have to be connected to their own power supplies?

Am I correct in this assumption? I purchased three 12v power supplies with the board, but I'm now worried that I'll need to purchase another one just to hook everything up! Am I correct in assuming that none of them can be powered via the board's 12v power supply? Can any of them be connected to a 12v power supply in sequence. *Especially valid because an alarm shouldn't ever be sounding (drawing power from a supply) at the same time as a buzzer.

And thus far I've connected it to Home Assistant via Esphome, but because my wireless networks have been hacked before I'd rather limit the A16's exposure to potential hacking attempts. Is there any other way to connect the A16 to Home Assistant so that it doesn't need to be constantly connected via ethernet?

Dear KINCONY Team

I already know some microprocessor like as PIC, Atmega and now. I want to learn ESP32.
After learning hardware. I know KINCONY have support Apply for free sample.
I hope i can be lucky enough to get it.

I am waiting your feedback.

Thank you so much. 

hi, this morning I found H32L disconnected. the network card is turned off and has no green LEDs on. ESP32 tuya module also fails to connect. I tried changing the cable but nothing.
from the input keys the plc works correctly. I attach a screenshot, where you can see that it is not online. what could have happened?
Thank you
