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
coils:
- name: Sensor1
hub: hub1
slave: 1
coil: 100
- name: Sensor2
hub: hub1
slave: 1
coil: 110
Configuration Variables
- coils
(map | list)(Required)
The array contains a list of coils 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).
- coil
(integer)(Required)
Coil number.
- 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:
