    ble_client_id: ble_client0
    check_crc: false

Atorch J7-C requires a disabled CRC check

atorch_dl24:
  - id: atorch0
    ble_client_id: ble_client0
    check_crc: false

Atorch DT3010

Supported but untested devices

Atorch AT24
Atorch AT3010
Atorch DT24
Atorch DT24PW (requires a disabled CRC check)
Atorch UD18
Atorch UD18-L

Atorch KM001

Requirements

ESPHome 2023.7.0 or higher.
Generic ESP32 (f.e. ESP32 NodeMCU or D1 Mini ESP32)

Installation

Use the esp32-dc-meter-example.yaml as proof of concept:

# Install esphome
pip3 install esphome

# Clone this external component
git clone https://github.com/syssi/esphome-atorch-dl24.git
cd esphome-atorch-dl24

# Create a secret.yaml containing some setup specific secrets
cat > secrets.yaml <<EOF
dl24_mac_address: MY_DL24_MAC_ADDRESS

wifi_ssid: MY_WIFI_SSID
wifi_password: MY_WIFI_PASSWORD

mqtt_host: MY_MQTT_HOST
mqtt_username: MY_MQTT_USERNAME
mqtt_password: MY_MQTT_PASSWORD
EOF

# Validate the configuration, create a binary, upload it, and start logs
esphome run esp32-dc-meter-example.yaml
