Unit NCIR Home Assistant Integration

This tutorial describes how to integrate the Unit NCIR single-point infrared thermometer sensor into Home Assistant to achieve non-contact temperature monitoring.

Preparation

• ESPHome supports MLX90614: MLX90614 datasheet
• Latest configuration reference: MLX90614 Non-Contact Infrared Thermometer

Note

Unit NCIR is a standalone sensor platform and requires an additional main controller (such as Atom series, Stamp series, Stick series, Core/Basic series, etc.) to be integrated into Home Assistant.

Modify Configuration

The I²C component needs to be enabled in the ESPHome configuration:

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

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

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

Unit NCIR Configuration Example:

sensor:
  - platform: mlx90614
    ambient:
      name: Ambient
    object:
      name: Object
    update_interval: 10s
