Hello,

 am trying to use a 2.4 Gz USB keyboard on the device and its just now shgowing up.  I have tried all 4 ports and re-bvooted device each attempt with no luck. Most R Pi 4s have 2 blue USB and 2 black but mine are all black.  I have looked ubder Settings >System>Hardware>All HARDWARE and there are no ebtries indicating an USB ports and definitely nothing looking like a wireless keyboard.  Tje CM4 is wells seated, not a connection issue.  My keyboard works on a windows PC and an Android TV box perfectly, its not the issue.

Any ideas please?

Thank you,
Mark Young

I have a  KC868-A16 would it be possible to control a standard computer fan 12v that has PWM ? i know there are some GPIO ports, im assuming i have to configure one of these as PWM, how do i find out which ones they represent on the actual board? The next question is how do i monitor the RPM form the fan and where do i connect and configure it ?

I'm new to this HW, so maybe I'm missing something.

I have a remote 433mhz that I "learned" on the Web UI.

When I transmit the signal, it is being sent around 5 times, triggering the receiving device to turn on and off and on again etc.
Basically, the device (ventilator) beeps when it gets a signal, and I'm hearing around 5 beeps.

Is there any way to configure this behavior?

Or should I flash the device with a different fimware? Can I just flash esphome on it - and hope to fix this somehow that way?

Current firmware: v2.2.4

Buenas tardes 

Quiero usar las entradas y al mismo tiempo una pantalla  oled i2c, pero no logro usarlo en conjunto correctamente, veo el código de ejemplo de entradas y ahí viene esto:

PC8574. pc8564(0x22,4,15)

Y en el código de ejemplo de OLED viene lo siguiente :

U8G2_SSD1306_128X64_NONAME_F_SW_I2C u8g2(U8G2_R0, 15, 4, U8X8_PIN_NONE);//SCL IO15 SDA IO4

y el error que hace es que siempre manda indicar que la entrada se activo cuando junto tanto un codigo como el otro 

Agradecería su apoyo

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.
