Unit ToF Home Assistant Integration

Unit ToF is a high-precision laser distance measurement unit. It features an integrated VL53L0X laser distance sensor that uses Time-of-Flight (ToF) technology to accurately calculate distance by measuring the round-trip time of laser light, and is not affected by target reflectivity.

VL53L0X is supported by default in ESPHome, making it convenient to integrate with Home Assistant

• VL53L0X datasheet

You can also refer to ESPHome to check the latest configuration

Configuring the Sensor

You need to enable the I²C component in your ESPHome configuration:

# Example configuration entry for ESP32
i2c:
  sda: GPIOXX
  scl: GPIOXX
  scan: true

The GPIO pins here will vary depending on the master device used. For example, using Atom Lite as the master:

# I2C Bus on Grove Port (HY2.0-4P)
i2c:
  sda: GPIO26
  scl: GPIO32

Example configuration for Unit ToF

sensor:
  - platform: vl53l0x
    name: "VL53L0x Distance"
    address: 0x29
    update_interval: 60s
    long_range: true

After saving the configuration file, compile and upload the firmware, then you can add the device to your Home Assistant integration
