How to install

From Home Assistant Web Browser

Requirements:
- ESPHome addon installed
- File editor addon installed
- Downloaded ESPHome-LM75A-Temperature-Sensor-Component github repo

1. using ESPHome Create project: my_project_name

2. using File Editor addon, go to path homeassistant/esphome/

3. upload LM75A.cpp file to the same folder as my_project_name.yaml.

4. upload LM75A.h file to the same folder as my_project_name.yaml.

5. Edit my_project.yaml file.

Add includes subsection of esphome.

esphome:
  includes:
    - LM75A.h
    - LM75A.cpp

Add I2C and sensor sections to end of file.

i2c:
  - id: bus_a
    sda: 4
    scl: 5
    scan: True
sensor:    
  - platform: custom
    lambda: |-
     auto lm75a = new LM75A();
     App.register_component(lm75a);
     return {lm75a};
    sensors:
      name: "LM75A Temperature"
      unit_of_measurement: °C
      accuracy_decimals: 1

6. on the top left corner, click Install

7. enjoy

ESPHome Command Line

1. Create project: esphome my_project.yaml wizard

2. Compile project: esphome my_project.yaml compile (this creates a project src folder)
