Dear all,
I’m in trouble with a script that I’ve tried to generate on my Raspi for Home Assistant.
Target: to generate manually with a Lovelace button a GPX file that contains the track of last 8 hours of a smartphone tracked via device tracker in Home Assistant.
Code used as follows:
FILE: /config/automations.yaml
CODE:
- id: generate_gpx_file
alias: Generate GPX File
trigger:
platform: event
event_type: call_service
event_data:
domain: automation
service: trigger
service_data:
entity_id: automation.generate_gpx_file
action:
service: python_script.execute
data:
script_id: generate_gpx_script
FILE: /config/python_scripts/generate_gpx.yaml
CODE:
generate_gpx:
sequence:
- service: python_script.execute
data:
script_id: generate_gpx_script
FILE: /config/python_scripts/generate_gpx_script.py
CODE:
# Estrapola i dati dell'entità "device_tracker.smartphone"
device_tracker = hass.states.get("device_tracker.smartphone")
history = device_tracker.attributes.get("history")
# Calcola l'orario di 8 ore fa
end_time = datetime.datetime.now()
start_time = end_time - datetime.timedelta(hours=8)
# Crea il contenuto del file GPX
gpx_content = """<?xml version="1.0"?>
<gpx version="1.1" creator="Home Assistant">
<trk>
<name>Historical Track</name>
<trkseg>
{% for event in history %}
{% if event[0] >= start_time and event[0] <= end_time %}
<trkpt lat="{{ event[1][0] }}" lon="{{ event[1][1] }}">
<time>{{ event[0].timestamp() | timestamp_local }}</time>
</trkpt>
{% endif %}
{% endfor %}
</trkseg>
</trk>
</gpx>
"""
# Scrivi il contenuto nel file GPX
file_path = "/config/generated_track.gpx"
with open(file_path, "w", encoding="utf-8") as file:
file.write(gpx_content)
FILE: /config/generated_track.gpx
No code here… it’s the file that should be overwritten with proper GPX content.
Please, could you help me to understand what happens? Thanks!
