Creating custom bus schedule

[felconkwk]

Hi, I’m new to Home Assistant and could use some help. I’m trying to input a list of bus timings for a private bus stop and have it track the next upcoming bus. However, I keep getting a message saying, “there are no more buses today.” I have the code save inside the configuration.yaml file as follow. Any help will be very much appreciated. Thank you.

sensor:
  - platform: template
    sensors:
      next_bus_stop_a_debug:
        friendly_name: "Next Bus at Bus Stop A (Debug)"
        value_template: >
          {% set current_time = now().strftime('%H:%M') %}
          {% set is_weekend = now().weekday() in [5, 6] %}
          {% set bus_stop_a_weekday_schedule = "06:30, 07:30, 08:30, 09:30, 10:30, 12:00, 13:00, 14:00, 16:00, 18:00" %}
          {% set bus_stop_a_weekend_schedule = "09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 16:00, 18:00" %}
          {% set bus_times_raw = bus_stop_a_weekend_schedule if is_weekend else bus_stop_a_weekday_schedule %}
          
          {# Debugging to print the raw schedule #}
          {% set debug_schedule = "Bus times (raw): " ~ bus_times_raw %}
          
          {# Split and clean the bus times #}
          {% set times_list = bus_times_raw.split(',') %}
          {% set cleaned_times_list = times_list | map('trim') | list %}
          
          {# Convert current time to a full datetime object #}
          {% set current_time_obj = strptime(now().strftime('%Y-%m-%d ') ~ current_time, '%Y-%m-%d %H:%M') %}
          {% set debug_current_time = "Current time: " ~ current_time ~ " (datetime: " ~ current_time_obj ~ ")" %}
          
          {# Initialize next bus variable #}
          {% set next_bus = None %}
          
          {# Compare each bus time after converting to a datetime object #}
          {% for time in cleaned_times_list %}
            {% set full_bus_time_str = now().strftime('%Y-%m-%d ') ~ time %}
            {% set bus_time_obj = strptime(full_bus_time_str, '%Y-%m-%d %H:%M') %}
            {% if bus_time_obj > current_time_obj %}
              {% set next_bus = time %}
              {% break %}
            {% endif %}
          {% endfor %}
          
          {# Output debugging information and next bus #}
          {{ next_bus if next_bus else "No more buses today" }}
          Debug: {{ debug_schedule }} | {{ debug_current_time }}

For future if anyone might be interested. I think I may have found a solution to what I am trying to get. Hope this will help.
