The modbus sensor allows you to gather data from Modbus registers.
To use your Modbus sensors in your installation, add the following to your configuration.yaml file:
# Example configuration.yml entry
sensor:
platform: modbus
registers:
- name: Sensor1
unit_of_measurement: °C
slave: 1
register: 100
- name: Sensor2
unit_of_measurement: mg
slave: 1
register: 110
count: 2
- name: Sensor3
unit_of_measurement: °C
slave: 1
register: 120
register_type: input
data_type: float
scale: 0.01
offset: -273.16
precision: 2
Configuration variables:
- registers array (Required): The array contains a list of relevant registers to read from.
- name (Required): Name of the sensor.
- slave (Required): The number of the slave (Optional for tcp and upd Modbus).
- register (Required): Register number.
- register_type (Optional): Modbus register type (holding, input), default holding
- unit_of_measurement (Optional): Unit to attach to value.
- count (Optional): Number of registers to read.
- scale (Optional): Scale factor (output = scale * value + offset), default 1
- offset (Optional): Final offset (output = scale * value + offset), default 0
- precision (Optional): Number of valid decimals, default 0
- data_type (Optional): Response representation (int, float). If float selected, value will be converted to IEEE 754 floating point format. default int
