Modbus Binary Sensor
The modbus binary sensor allows you to gather data from Modbus coils.
Configuration
To use your Modbus binary sensors in your installation, add the following to your configuration.yaml file:
# Example configuration.yaml entry
binary_sensor:
- platform: modbus
inputs:
- name: Sensor1
hub: hub1
slave: 1
address: 100
- name: Sensor2
hub: hub1
slave: 1
address: 110
input_type: discrete_input
Configuration Variables
- inputs
(map | list)(Required)
The array contains a list of coils and discrete inputs to read from.
- name
(string)(Required)
Name of the sensor.
- hub
-
(string)(Optional)
The name of the hub.
Default value:
default
- slave
(integer)(Required)
The number of the slave (Optional for TCP and UDP Modbus).
- address
(integer)(Required)
Coil or discrete input Modbus address.
- input_type
(string)(Optional)
Modbus input type (coil, discrete_input), default coil.
- device_class
-
(device_class)(Optional)
The type/class of the binary sensor to set the icon in the frontend.
Default value:
None
It’s possible to change the default 30 seconds scan interval for the sensor updates as shown in the Platform options documentation.
Full example
Example a sensor with a 10 seconds scan interval:
