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:

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?

Hello,
can you please point me to a step by step guide on how to update the AK firmware to the latest version?
regards

dear admin,

I would like to connect the "Wired Water Leak Sensor" https://shop.kincony.com/products/wired-...282c&_ss=r to the KC868-A16 module and read the flood value in HomeAssistant in ESPHome.

> could you please publish the wiring diagram for the "Wired Water Leak Sensor" connection to A16?
> the sensor is connected to a digital input and is thus used as an active input in ESPHome?

regards

I would like to use mqtt + Tuya controlling via homeassistent, however, this is a challenge for me. My board is kc-868-A8. Thank you for your attention.

I have a SIM800 modem. How can I transfer data via GPRS to my home assistant server (for example MQTT) or the Tuya cloud if I do not have an Ethernet and WiFi connection.
I use firmware 2.2.7 - there you can only SIM7600

Hello
 
I wonder if it possible to use ADC A1, A2, A3 and A4 as a digital input for a switch?

I will using A6 with esphome.

Thank you

On the A8S v2 controller and A8S-EXT-V1.0 expansion module, toggle switch S1 (and LED) corresponds to relay8, toggle switch S2 corresponds to relay7, etc.
Is this a known bug and will it be fixed?

dear admin,

I am using KC868-A16 and I need to connect temperature and humidity sensors to 3 1-Wire inputs. I connected DS18B20 sensors to pins "GPIO32" and "GPIO33" and DHT22 sensor (/AM2302) to pin "GPIO14". When installing the module in HomeAssistant add-on ESPHome, DS18B20 sensors are loaded correctly, but DHT22 sensor is not found. I tried two DHT22 sensors with the same result.

This is the code in YAML
###
one_wire:
  - platform: gpio
    pin: GPIO32
    id: one_wire1
  - platform: gpio
    pin: GPIO33
    id: one_wire2
  - platform: gpio
    pin: GPIO14
    id: one_wire3
.

sensor:
  - platform: dallas_temp
    address: 0x773ce1d458ac1a28
    name: temperature1
    update_interval: 120s
    one_wire_id: one_wire1
  - platform: dallas_temp
    address: 0xfd3ce1d4432b6528
    name: temperature2
    update_interval: 120s
    one_wire_id: one_wire2

The attached image is a screenshot from the installation.
   

Please could you help me? Where am I making a mistake?

Is this the correct code to get values from DHT22?
###
- platform: dht
    model: DHT22
    one_wire_id: one_wire3
    temperature:
      name: "Temperature3"
    humidity:
      name: "Humidity3"
