esphome-LM75

Basic esphome support for LM75.

The LM75 is a 2-wire digital temperature sensor with an analog-to-digital converter and I2C interface. The LM75 provides readings with accuracy of +/-2°C from -25°C to 100°C and +/- 3°C from -55°C to 125°C.

The I²C Bus is required to be set up in your configuration for this sensor to work.

Inspired by esphome-PCT2075 and tmp102 implementations.

Support only reading temperature!

Instalation

Configure external compoenet:

external_components:
  - source: github://btomala/esphome-LM75@v1
    components: [ lm75 ]

And addit to the sensors section:

sensor:
  - platform: lm75
    id: temperature
    name: "Board temperature measurement"
    update_interval: 60s
    address: 0x48

Configuration variables:

• name (Required, string): The name for the temperature sensor.
• update_interval (Optional, Time): The interval to check the sensor. Defaults to 60s.
• address (Optional, int): The I²C address of the sensor. Defaults to 0x48.
• id (Optional, ID): Set the ID of this sensor for use in lambdas.
• All other options from Sensor.

TODO

Support for:

• setting up configuration
• hysteresis
• over-temperature output (O.S.)
