Serial Bridge for Bentel Kyo32G Alarm System.

ESPhome for BENTEL KYO32G

Serial Bridge for Bentel Kyo32G Alarm Central, based on ESP8266 Board and ESPHome Open Source Firmware. Thanks to @dario81 for initial porting to ESPHome.

Hardware Connections

As board I used a WeMos D1 Mini (https://it.aliexpress.com/item/32651747570.html) but any board based on ESP8266 should be fine.

In order to connect to the serial port of the Kyo32 Unit I recommend a connector based on MAX3232 chip, like this https://it.aliexpress.com/item/32722395554.html This connector should be connected to the classic TX/RX of the ESP board and to the power supply (GND, 5V) on WeMos.

The WeMos can be powered with USB directly from the 12V output of the control unit by connecting any 12V->USB converter.

Which I recommend because in this way, even in case of power failure, the ESP is powered by the battery of the control unit.

Firmware Preparation

The file espkyogate_configuration.yaml is already present in this repo. I suggest you start from this.

Set your WiFi ssid and password in wifi section.

Set uart settings in base depending on the board you use, example file is for Wemos D1 mini. Finally edit binary_sensors you want to see on your Home Assistant as configured in the example file.

Build and Upload Firmware

With ESPHome

This way is the easiest, just copy the files from this repository to the esphome folder, edit the espkyogate_configuration.yaml file as above, upload and see if everything works from the logs. You should see something similar.

From esphome command line

python3 -m esphome espkyogate_configuration.yaml compile python3 -m esphome espkyogate_configuration.yaml run

Check logs

See logs with this command python3 -m esphome espkyogate_configuration.yaml logs

Output should be the same as above.

Usage

If everything went well now you should find a new device in Home Assistant, called espkyogate. Previously configured sensors will be automatically created and associated to the device.

Avaiable Services

These methods will be available in the services

Area Arm

service: esphome.espkyogate_arm_area
data:
  arm_type: 1 (total arm) - 2 (partially arm)
  area: <area_number>
  specific_area: 1 (arm <area_number> and disarm others) - 0 (arm only <area_number> without changing the others)

Area Disarm

service: esphome.espkyogate_disarm_area
data:
  area: <area_number>
  specific_area: 1 (disarm all areas) - 0 (disarm only <area_number> without changing the others)

Reset Alarm Memory

service: esphome.espkyogate_reset_alarms
data: {}

Activate Output

If an output is configured as 'Remote Command' (Comando Remoto) you can Activate or Deactivate

service: esphome.espkyogate_activate_output
data:
  output_number: <output_number>

Deactivate Output

If an output is configured as 'Remote Command' (Comando Remoto) you can Activate or Deactivate

service: esphome.espkyogate_deactivate_output
data:
  output_number: <output_number>

Arm more than one area

If you want to arm several areas at the same time you have to call the same service several times, introducing a delay between one call and the next. Below is an example of a script that arms two areas.

alias: Bentel Arma Fuori Casa
sequence:
  - service: esphome.espkyogate_arm_area
    data:
      area: 1
      arm_type: 1
      specific_area: 1
  - wait_template: ''
    timeout: '00:00:05'
  - service: esphome.espkyogate_arm_area
    data:
      area: 2
      arm_type: 1
      specific_area: 1
  - wait_template: ''
    timeout: '00:00:05'
  - service: esphome.espkyogate_arm_area
    data:
      area: 3
      arm_type: 1
      specific_area: 1
mode: single

Troubleshooting - FAQ

Ff you have any problems, make the following checks:

• Check that the cables are connected correctly
• Check the 232 converter is properly powered
• Try to reverse TX and RX
• Verify that the central unit has firmware 2.13

Diagnostics Service

For diagnostics you can enable additional software logs through this service. If necessary, contact me with an extract of the logs so that I can help you better.

service: esphome.espkyogate_debug_command
data:
