esphome-hcpbridge

This is a esphome-based adaption of the HCPBridge. Credits for the initial development of the HCPBridge go to Gifford47, hkiam and all the other guys contributed.

  - platform: hcpbridge
    name: ${friendly_name}
    device_class: garage
    id: garagedoor_cover

Home Assistant

Cover

The component provides a cover component to control the garage door.

Light

The component provides a Light component to turn the light off and on. The Output is needed to control the light.

output:
  - platform: hcpbridge
    id: output_light

light:
  - platform: hcpbridge
    id: gd_light
    output: output_light
    name: Garage Door Light

Binary_Sensor

The component provides you two sensor.

• is_connected: Who indicated if there is a valid connection with the door.
• relay_state: Give the status of the option relay (Menu 30) of the HCP.

binary_sensor:
  - platform: hcpbridge
    is_connected:
      name: "HCPBridge Connected"
      id: sensor_connected
    relay_state:
      name: "Garage Door Relay state"
      id: sensor_relay
      #on_state:
      #create your automation based on Garage Door Relay state

Text_sensor

This component provide you a detailed current state of the door. This text can be changed using the substitute functionality.

text_sensor:
  - platform: hcpbridge
    id: sensor_templ_state
    name: "Garage Door State"

Button

This component allows you to add three buttons to sond commands to the door.

button:
  - platform: hcpbridge
    vent_button:
      id: button_vent
      name: "Garage Door Vent"
    impulse_button:
      id: button_impulse
      name: "Garage Door Impulse"
    half_button:
      id: button_half
      name: "Half"

Switch

This component allows you to add two switch to sond commands to the door.

switch:
  - platform: hcpbridge
    vent_switch:
      id: switch_vent
      name: "Venting"
      restore_mode: disabled
    half_switch:
      id: half_switch
      name: "Open Half"
      restore_mode: disabled

Services

Additionally, when using the cover component, you can expose the following services to the API:

• esphome.hcpbridge_go_to_close: To close the garage door
• esphome.hcpbridge_go_to_half: To move the garage door to half position
• esphome.hcpbridge_go_to_vent: To move the garage door to the vent position
• esphome.hcpbridge_go_to_open: To open the garage door
• esphome.hcpbridge_toggle: Send an Impulse command to the door

There are in the YAML and not directly in the Cover to remove the API dependency there. This give the possibility to use the Cover without the API Component for exemple only with the web_server or mqtt.

api:
  encryption:
    key: !secret api_key
  services:
    - service: go_to_open
      then:
        - lambda: |-
            id(garagedoor_cover).on_go_to_open();
    - service: go_to_close
      then:
        - lambda: |-
            id(garagedoor_cover).on_go_to_close();
    - service: go_to_half
      then:
        - lambda: |-
            id(garagedoor_cover).on_go_to_half();
    - service: go_to_vent
      then:
        - lambda: |-
            id(garagedoor_cover).on_go_to_vent();
    - service: toggle
      then:
        - cover.toggle: garagedoor_cover

Project

• HCPBridge from Tysonpower on an Hörmann Promatic 4

You can find more information on the project here: Hörmann garage door via MQTT

ToDo

• Initial working version
• Use esphome modbus component instead of own code
• Map additional functions to esphome
• Use callbacks instead of pollingComponent (Only hcpbridge is polling)
• Expert options for the HCPBridge component (GPIOs ...)
