Guide - XTRAFIT Fitness Studio Sensor

[N1c093]

Hello everyone,

I’ve just created a custom REST sensor for monitoring the occupancy of fitness studios of the german fitness studio XTRAFIT directly within Home Assistant.

This setup allows you to track the occupancy of your selected gym as a percentage. The API is queried every 5 minutes and the sensor directly calculates the occupancy using a simple template.

Configuration

- sensor:
  - platform: rest
    name: Fitnessstudio Auslastung
    resource: https://exerp.xtrafit.de/api/centers/capacity
    method: GET
    scan_interval: 300
    json_attributes_path: "$.capacityInfos[?(@.centerId==YOUR_CENTER_ID)]"
    json_attributes:
      - centerId
      - currentlyCheckedInCount
      - maximumAllowedCheckedIn
      - numberOfAvailableSpots
      - webName
    value_template: >-
      {% set center = value_json.capacityInfos | selectattr('centerId', 'eq', YOUR_CENTER_ID) | list | first %}
      {% if center and center.maximumAllowedCheckedIn | int > 0 %}
        {{ (center.currentlyCheckedInCount | int / center.maximumAllowedCheckedIn | int * 100) | round(0) }}
      {% else %}
        0
      {% endif %}
    unit_of_measurement: "%"
    icon: mdi:weight-lifter

How to change your location

1. Replace YOUR_CENTER_ID with the ID of your desired gym.
2. You can find the available IDs here: https://exerp.xtrafit.de/api/centers/capacity.

Example: Wiesbaden Hauptbahnhof (ID: 260)

- sensor:
  - platform: rest
    name: Fitnessstudio Auslastung Wiesbaden
    resource: https://exerp.xtrafit.de/api/centers/capacity
    method: GET
    scan_interval: 300
    json_attributes_path: "$.capacityInfos[?(@.centerId==260)]"
    json_attributes:
      - centerId
      - currentlyCheckedInCount
      - maximumAllowedCheckedIn
      - numberOfAvailableSpots
      - webName
    value_template: >-
      {% set center = value_json.capacityInfos | selectattr('centerId', 'eq', 260) | list | first %}
      {% if center and center.maximumAllowedCheckedIn | int > 0 %}
        {{ (center.currentlyCheckedInCount | int / center.maximumAllowedCheckedIn | int * 100) | round(0) }}
      {% else %}
        0
      {% endif %}
    unit_of_measurement: "%"
    icon: mdi:weight-lifter
