Binary_Sensor - Get specific attribute

Configuration
1

Hello,

I encounter a problem to get a specific attribute (round_trip_time_avg) from a binary sensor.
Here is my configuration :

binary_sensor:

  • platform: ping
    name: Nuc01
    host: 192.168.5.5
    count: 4
    scan_interval: 60
  • platform: template
    sensors:
    ping_nuc01:
    device_class: connectivity
    entity_id:
    - binary_sensor.nuc01
    value_template: “{{ state_attr(‘binary_sensor.nuc01’, ‘round_trip_time_avg’) }}”

After restarting HA, I check in dev tool the state for the entity binary_sensor.ping_nuc01, The indicated state is “Off” which is not the expected result.

Can you tell me where is my mistake here ?

A binary sensor can only be on or off (binary). You need to use a regular (analog) template sensor to display that attribute. That template sensor will go under sensor: in your config.

Hi Tediore,

Thanks for the tips, it seems logical by the way :).
I got the expected result with this configuration :slight_smile:

#------MONITORING SECTION------#
binary_sensor:

  • platform: ping
    name: Nuc01
    host: 192.168.5.5
    count: 4
    scan_interval: 60 #30 secondes
    #–SENSOR SECTION–#
    sensor:
    #Ping sensor Latency
  • platform: template
    sensors:
    ms_nuc01:
    friendly_name: “Latence Nuc01”
    unit_of_measurement: ‘ms’
    value_template: “{{ state_attr(‘binary_sensor.nuc01’, ‘round_trip_time_avg’) }}”

By the way, when asking questions like this in the future, be sure to format your code properly. Use three backticks (```) above and below the code, otherwise we can’t see if there are indentation issues

@Tediore
Would you be so kind to assist me, I cannot get it to work and even worse I do not get any error.
The check configuration tool just keeps looping without presenting me with an error.
The binary sensor ping works without the template.

binary_sensor:
  - platform: ping
    host: 8.8.8.8
    name: "google ping"
    count: 5
    scan_interval: 30
    
  - platform: template
    sensors:
       google_ping_time_avg:
       friendly_name: "google ping time avg"
       unit_of_measurement: "ms"
       value_template: "{{ state_attr('binary_sensor.google_ping', 'round_trip_time_avg' }}"

The indentation for the template sensor is not correct:

- platform: template
    sensors:
       google_ping_time_avg:
		   friendly_name: "google ping time avg"
		   unit_of_measurement: "ms"
		   value_template: "{{ state_attr('binary_sensor.google_ping', 'round_trip_time_avg' }}"

You’re missing a closing parenthesis: ...'round_trip_time_avg') }}"
Keep in mind you have the Developer Tools - Template to test your templates.

Awesome everyone. It now works.
