Nuki Bridge Firmware Arduino Framework

This configuration inherits all features from the Stock Firmware and adds a Nuki Bridge component via BLE. Note that it does not support Improv via Bluetooth LE, as the BLE stack is used by the Nuki Bridge component.

Update Firmware

There are several ways to update the firmware:

• ESPHome OTA Requires ESPHome Dashboard
• HTTP OTA Latest release build, no customization
• Web Serial Latest release build, no customization

You can connect your Doorman via USB-C and click the button below to install the latest Doorman Nuki Bridge Firmware directly through Web Serial.

Firmware YAML

This is the minimal ESPHome configuration YAML file. Be sure to update the API key.

Pairing your Nuki Lock

Depending on the PCB revision, either press the FLASH or PRG button on the Doorman PCB for 5 seconds until the status LED starts flashing purple, or enable the Nuki Pairing Mode switch in Home Assistant. Then, press the button on your Nuki Lock for 5 seconds until the light ring turns on.

After a successful pairing, the status LED will remain steadily on for 3 seconds.

WARNING

If your Nuki Lock is already paired, this process will unpair it!

Unpairing your Nuki Lock

You can unpair your device using either the Nuki Unpair Device button in Home Assistant or the physical FLASH or PRG button on the Doorman PCB.

Physical Button

If your lock is already paired with Doorman, press the FLASH or PRG button on the Doorman PCB for 5 seconds until the RGB status LED starts flashing purple. Your Nuki Lock will then be unpaired. Note that the pairing mode will time out after 30 seconds.

Examples

Create a simple TC Command Binary Sensor

You can easily add additional binary sensors for any TC Command, alongside the preconfigured ones.

Controlling the internal RGB Status LED

If you want to control the onboard RGB LED with a button (for example), simply use the Light ID: doorman_rgb_status_led.

          blue: 0%

Use the External Hardware Button

If you want to use the external button to trigger automations, you can simply extend your YAML configuration.

    on_press: 
      - logger.log: "External button pressed!"

Use I²C Sensors

If you want to add sensors via the I²C bus, you can use the two available GPIO pins and add the I²C component to your configuration. You can then attach your sensors to these two I²C GPIO pins.

Advanced Examples

Home Assistant

Sending Bus commands

You can use Home Assistant actions (formerly known as services) to send commands on the bus. Either use the command to send raw commands or type, address, payload and serial_number to send commands via the command builder.

INFO

Remember to include the leading 0x when calling the action with the command property. If you omit it, you'll need to convert the HEX command to a decimal number first.

Command Builder:

service: esphome.doorman_s3_send_tc_command
data:
  type: open_door
  address: 0
  payload: 0
  serial_number: 123456

32-Bit Commands via command:

service: esphome.doorman_s3_send_tc_command_raw
data:
  command: 0x11E24080

Listening for ESPHome events

Doorman will send esphome.doorman events to Home Assistant every time a command is received.

Each event is structured as follows:

event_type: esphome.doorman
data:
  device_id: 373c62d6788cf81d322763235513310e
  command: "00001100"
  type: "open_door"
  address: "0"
  payload: "0"
  serial_number: "0"
origin: LOCAL
time_fired: "2024-08-12T12:34:13.718317+00:00"
context:
  id: 01J5399Y2PP2XS2VRYKBT3H3AV
  parent_id: null
  user_id: null

Automation Example (HEX Command):

alias: Trigger on Doorman TC Open Door Command
description: ""
trigger:
  - platform: event
    event_type: esphome.doorman
    event_data:
      command: "00001100"
condition: []
action: []
mode: single

Automation Example (Command Builder):
