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.

Usage

Example esphome configuration

esphome:
  name: hcpbridge
  libraries:
    - emelianov/modbus-esp8266 # Required for communication with the modbus
  platformio_options:
    board_build.f_cpu: 240000000L
    board_build.flash_mode: qio
    monitor_speed: 9600
    monitor_filters: esp32_exception_decoder
    lib_ldf_mode: deep+
    # board_build.f_flash: 40000000L

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.

Additional Components

Information like the current position or the state of the option relay (Menu 30) can be added using Templates. Check out the example_hcpbridge.yaml for some implementations.

Services

Additionally, when using the cover component, you can use the following services:

• 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

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
• Expert options for the HCPBridge component (GPIOs ...)
