trying to use DAC1/2 by following simple code:
can't see any changes on output nor on esp32(25/26)
dac_output_enable(DAC_CHANNEL_1);
dac_output_enable(DAC_CHANNEL_2);
dac_output_voltage(DAC_CHANNEL_1,0);
dac_output_voltage(DAC_CHANNEL_2,0);

i see no changes no matter the values, how come ?

what is the meaning for Strapping is it needed any human interact to activate it?

Hello, i'm tryng to read inputs from the PCF8574 channels. This is my code:

Hi Xu Wei,

Good day, I need assitance for two things.

1. My DHT sensor not reading temperature and the ESPHome log messages output below.

Hello everyone, we're trying to use a custom arduino script (with homespan) to control the board with apple homekit.
We managed to connect the board and homekit setting fake lightbulbs properly, but the problem is that the status leds of the outputs don't turn on.
We want to control every output (and related status leds) with homekit.
We've already checked the kc868-a16 schematic, but it doesnt' explain what pins to connect for the outputs
(we already tried pins 2 and 15, as your video for the A4 showed, and pins 1, 2, 3, 4, 5, but without results).
As your video explained (this video: https://www.youtube.com/watch?v=CkCJESr2n-U) we've uploaded the arduino script with homespan installed,
the connection works, but the pins don't correspond (for the kc868-a16)

Hi,
im currently building a house with automation. While searching I stumbled upen your system wich I really do appreciate cause it looks like exactly what I was looking for. I wanted to start with the A32 for first tests. Question is: in germany we're used to use 24VDC for automation. For the outputs it's not a problem as i will use own couple relais.
Question is:
Are the inputs tolerant to 24VDC? Or can they be if I use additional resistors? Datasheet of the EL357 says 80V is fine but I'm not sure if it is FET inputs and want to be sure before ordering.
Thank you and keep on your good work! Really like!

I have a usecase for the kc868-a6 that requires the bluetooth to work with esphome. As soon as I enable anything bluetooth related I get fatal errors and the wifi never connects to the network.
This is the code I am trying to use that appears to corrupts the esp32.

substitutions:
name: test
mac_address: C8:47:8C:E1:E2:E2

esp32_ble_tracker:

ble_client:
- mac_address: ${mac_address}
id: client0

switch:
- platform: ble_client
ble_client_id: client0
name: "enable bluetooth connection"

Any thoughts on why the esp32  does not like the bluetooth settings? After removing the bluetooth settings and reflashing I am able to connect to the controller again.
Thanks in advance.
Andy

I've defined the digital inputs and switches as in the example and also added a DS18B20 temp sensor to the I2C. But as soon as I add in yaml the Dallas configuration, the update_interval toggles the switches on and off at the interval set in the update_interval.
I saw that the I2C port is the same as the Dallas sensor but I don't know how I can connect them in a different way.

Good afternoon.
In my project, a water level sensor and a temperature sensor are connected to the KC868 A4 controller.
Please tell me which program is better to monitor the readings from the sensor. I tried to connect to Homekit, there were no problems with the temperature sensor, but I didn’t understand how to make the status bar for filling the tank with water.

Maybe tell me how best to implement control from the phone for these sensors through the 4
A4 controller?
