An ESPHome custom component for controlling a Novy Pureline Pro extractor hood over Bluetooth Low Energy (BLE) via an ESP32.

This integration is based on reverse-engineering the communication between the official mobile app and the extractor hood.

https://github.com/bwynants/hass-purelinepro is similar, but is a HA integration

Tested with Novy Pureline Pro and Novy Cloud extractor

To discover the MAC address, service UUIDs, and iBeacon UUIDs, use the following ESPHome configuration:

esp32_ble_tracker:
  on_ble_advertise:
    - then:

logger:
  level: VERY_VERBOSE

Check the ESPHome logs to identify the MAC address associated with your Pureline Pro extractor hood.

external_components:
  - source:
      type: git
      url: https://github.com/bwynants/purelinepro
      ref: main
    components: [purelinepro]

Place the component in your ESPHome components/ directory:

external_components:
  - source:
      type: local
      path: components

esp32_ble_tracker:
  scan_parameters:
    interval: 1100ms
    window: 1100ms
    active: false

Replace the MAC address with your device's address:

ble_client:
  - mac_address: "00:00:00:00:00:00"
    id: purelinepro_ble_id

purelinepro:
  - id: novydampkap
    ble_client_id: purelinepro_ble_id

• Recirculate: Toggles between normal and recirculate mode.
• Enabled: Enables/disables BLE connection (disable to pair with another device).

switch:
  - platform: purelinepro
    purelinepro_id: novydampkap
    recirculate:
      name: Recirculate
    enabled:
      name: Enabled

Single light (combines white/ambient), supports color and brightness control.

light:
  - platform: purelinepro
    purelinepro_id: novydampkap
    name: "Extractor Light"
    id: extractor_light
    restore_mode: RESTORE_DEFAULT_OFF

Useful remote-like actions:

• power: simulates power of remote
• delayed_off: if clicked it sets the fan to 25% and puts it off after 5 minutes
• set_default_light: sets default light for ambi or white, if ambi or white mode is not active it does nothing....
• ambi_light: start ambi light mode
• white_light: start white light mode
• set_default_speed: sets default speed
• reset_grease: resets grease filter timer

button:
  - platform: purelinepro
    purelinepro_id: novydampkap
    power:
      name: "Power Toggle"
    delayed_off:
      name: "Delayed Off"
    reset_grease:
      name: "Reset Grease"
    set_default_light:
      name: "Set Default Light"
    set_default_speed:
      name: "Set Default Speed"
    ambi_light:
      name: "Ambi Light"
    white_light:
      name: "White Light"

fan:
  - platform: purelinepro
    purelinepro_id: novydampkap
    name: "Extractor Fan"
    id: extractor_fan
    restore_mode: RESTORE_DEFAULT_OFF

Monitor extractor hood status and usage:

• off_timer: when in cooldown mode, this gives how long remaining before off
• boost_timer: when in boost mode (fan +75%) this is the remaing time before the fan speed gets lowered
• grease_timer: remainig time before grease filter needs cleaning
• operating_hours_led: total hours the leds where on
• operating_hours_fan: total hours the fan was on

sensor:
  - platform: purelinepro
    purelinepro_id: novydampkap
    off_timer:
      name: Off Timer
    boost_timer:
      name: Boost Timer
    grease_timer:
      name: Grease Timer
    operating_hours_led:
      name: LED Hours
    operating_hours_fan:
      name: Fan Hours

• cleangrease: Indicates when the grease filter needs cleaning.

binary_sensor:
  - platform: purelinepro
    purelinepro_id: novydampkap
    cleangrease:
      name: Clean Grease
      disabled_by_default: false

• When using light_transition for smooth transitions in Bubble Card sliders, the light crashes because too many requests are sent in a short time.
