The `modbus` binary sensor allows you to gather data from [Modbus](http://www.modbus.org/) coils.
|
|
|
|
## {% linkable_title Configuration %}
|
|
|
|
To use your Modbus binary sensors in your installation, add the following to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
binary_sensor:
|
|
- platform: modbus
|
|
coils:
|
|
- name: Sensor1
|
|
slave: 1
|
|
coil: 100
|
|
- name: Sensor2
|
|
slave: 1
|
|
coil: 110
|
|
```
|
|
|
|
{% configuration %}
|
|
coils:

It's possible to change the default 30 seconds scan interval for the sensor updates as shown in the [Platform options](/docs/configuration/platform_options/#scan-interval) documentation.
|
|
|
|
## {% linkable_title Full example %}
|
|
|
|
Example a sensor with a 10 seconds scan interval:
|
|
|
|
```yaml
|
|
binary_sensor:
|
|
- platform: modbus
|
|
scan_interval: 10
|
|
coils:
|
|
- name: Sensor1
|
|
slave: 1
|
|
coil: 100
|
|
- name: Sensor2
|
|
slave: 1
|
|
coil: 110
|
|
```
