  KC868-A4S for heating controll
Posted by: tadam - 11-27-2024, 01:05 PM - Forum: KC868-A4S - Replies (9)

Hello there,

I am looking for confirmation before purchase that I can use this board as I plannig to. Smile
So my plan is to use this board for central heating management. I attached a picture how does the setup looks so far.
I will use Home assistant and esphome.
As you can see I have 
- 4 24V AC valve.
- 5 temperature sensor (ds18B20)
- analog pressure sensor (SEN0257)
- leak sensor (just a basic contact sensor)
- opentherm adapter (this one)
- for network connection I will use ethernet

Do I need an additonal power supply (9-24V DC) to power my board? Or it can be power from 5V?

4x 24V AC valve: This is easy, They can go to the 4 relay. I think I will use the normaly closed terminals, in case of a board issue, the heating should not be affected. There is a separate 24V AC power supply, which only responsible for powering these valves.

5 temperature sensor (ds18B20): As far as I know these sensors has uniq id and can use the same pin, with one wire protocol. I can use the 3.3V output and ground from the board, and GPIO01 for the onewire.

analog pressure sensor (SEN0257): This sensor needs 5V can I get 5V out of this board? The output of this sensor is analog, so I can use AI1 for that.

leak sensor: This is just a digital sensor this is trivial too, it can go DI1 and ground.

opentherm adapter: This board need 3.3V, this I can get from the board. But also needs 2 free IO. Is there an IO I can repurpose in this case? There is only one free "bare" gpio left which is this case GPIO2. All other looks like has a special purpose.

I am really excited for this project and looking forward for responses. Thanks in advance.

Is there a detailed user manual available for the Kincony Server 16 that includes the I/O port numbers or addresses? I need this information to utilize the device's pins and ports more efficiently for my application.

  kcs firmware system source code
Posted by: davidbvega - 11-26-2024, 11:25 AM - Forum: Development - Replies (1)

Good morning!

I wanted to know if you have available the firmware source code that you provide for the KC868-A8-V1.6 board.

I want to extend functionalities needed for my project, but if it is possible, starting from your base.

Best regards!

  Read 12V battery charge
Posted by: darsh - 11-25-2024, 11:03 AM - Forum: KC868-A6 - Replies (7)

Hello,
I am powering the board with a solar panel connected to a charge controller and a 12V battery. I have installed the ESPHome system on the board connected to Home Assistant, and it is working perfectly.

I would like to read the battery charge level using the analog sensor A1, but I know that this sensor reads a maximum of 5V, so the 12V from the battery (13V when fully charged) needs to be reduced. For this, I tried using a voltage divider circuit with two resistors, one 200KOhm and one 100KOhm. I connected the GND and A1 terminals of the analog sensors across the 100KOhm resistor, with the GND terminal going to the negative terminal of the battery.

+12V (Battery)
      |
      |
    [R1]  200kOhm
      |
      +------ A1
      |
    [R2]  100kOhm
      |
      |
    GND (Battery -)

The configuration in ESPHome is:

Code:
sensor:
  - platform: adc
    pin: 36
    name: 'Battery Charge - Voltage'
    id: battery_charge_voltage
    accuracy_decimals: 5
    device_class: "voltage"
    state_class: "measurement"
    unit_of_measurement: "V"
    update_interval: 5s
    filters:
    - multiply: 24.6

This configuration gives me readings of values below 0, which I had to multiply by 24.6 to get battery voltage values close to what I read using a voltmeter connected to the battery terminals.

Additionally, the values read are not stable, while the voltmeter provides a rather stable value.

Can you tell me if I am making any mistakes in the configuration or in the circuit? Is there a simpler way to perform this reading?

Thank you.

Darsh

  M16 Incorrect current reading
Posted by: salvolivigni - 11-23-2024, 05:06 PM - Forum: KC868-M16 / M1 / MB / M30 - Replies (1)

Hi Admin, I recently purchased the M16 and 13 SCT013 board, I configured everything with esphome, so far everything is ok. But when I go to read the values of the specific probes, comparing them for example with a PZEM 0-16, I have values in watts very far from the real absorption, I also did a comparison with a clamp meter, and unfortunately the M16 probes all read values much higher than reality. For the voltage I solved it by modifying the file #define SENSITIVITY 525.0f, and now the voltage is correct, but unfortunately for the wattage I can't find a solution, can you help me?
