:description: Instructions for setting up a Binary Sensor Map

|
|
|
|
The ``binary_sensor_map`` sensor platform allows you to map :doc:`binary sensor </components/binary_sensor/index>`
|
|
to values. When a given binary sensor is on, the value associated with it in this platform's configuration will be published.
|
|
|
|
This sensor is **mostly used for touch** devices but could be used for any ``binary_sensor`` that publishes its ``ON`` or ``OFF`` state.
|
|
|
|
Add your binary sensors as ``channels`` to the binary sensor map. The binary sensor map then publishes a value depending
|
|
on the type of the binary sensor map and the values specified with each channel. The maximum amount of possible channels is 64.
|
|
|
|
This platform currently supports two measurement types: ``GROUP`` and ``SUM``, and others might get added later.
|
|
You need to specify which type of mapping you want with the ``type:`` configuration value:
|
|
|
|
- ``GROUP`` Each channel has its own value. The sensor publishes the average value of all active
|
|
binary sensors.

# Example configuration entry
|
|
sensor:
|
|
- platform: binary_sensor_map
|
|
id: group_0
|
|
name: 'Group Map 0'
|
|
type: GROUP
|
|
channels:
|
|
- binary_sensor: touchkey0
|
|
value: 0
|
|
- binary_sensor: touchkey1
|
|
value: 10
|
|
- binary_sensor: touchkey2
|
|
value: 20
|
|
- binary_sensor: touchkey3
|
|
value: 30

# Example binary sensors using MPR121 component
|
|
mpr121:
|
|
id: mpr121_first
|
|
address: 0x5A
|
|
|
|
binary_sensor:
|
|
- platform: mpr121
|
|
channel: 0
|
|
id: touchkey0
|
|
# ...
|
|
|
|
- ``SUM`` Each channel has its own value. The sensor publishes the sum of all active
|
|
binary sensors values.

|
|
|

Configuration variables:
|
|
------------------------
|
|
|
|
- **name** (**Required**, string): The name of the sensor.
|
|
- **type** (**Required**, string): The sensor type. Should be one of: ``GROUP``.
|
|
- **channels** (**Required**): A list of channels that are mapped to certain values.
|
|
|
|
- **binary_sensor** (**Required**): The id of the :doc:`binary sensor </components/binary_sensor/index>`
|
|
to add as a channel for this sensor.
|
|
- **value** (**Required**): The value this channel should report when its binary sensor is active.
|
|
|
|
- All other options from :ref:`Sensor <config-sensor>`.
