The modbus binary sensor allows you to gather data from Modbus coils.
{% linkable_title 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 %} coils: description: The array contains a list of coils to read from. required: true type: [map, list] keys: name: description: Name of the sensor. required: true type: string hub: description: The name of the hub. required: false default: default type: string slave: description: The number of the slave (Optional for TCP and UDP Modbus). required: true type: integer coil: description: Coil number. required: true type: integer {% endconfiguration %}
It's possible to change the default 30 seconds scan interval for the sensor updates as shown in the Platform options documentation.
