It receives `LOCATE` commands via [ntfy](https://ntfy.sh) push notifications and replies with the device's current GPS coordinates and battery level. + +The app has no background service of its own — it uses the ntfy Android app as a trigger via Broadcast Intents. + +## How It Works + +``` +Server ntfy.sh Phone + | | | + |-- POST "LOCATE" to topic ---->| | + | |-- Push notification -------->| + | | | ntfy app broadcasts intent + | | | NtfyReceiver catches it + | | | WorkManager starts LocationWorker + | | | Gets GPS + battery level + | |<-- POST location ------------| + |<-- Subscribe / poll --------- | | + | | | +``` + +1. The **ntfy app** (installed separately) subscribes to a topic and receives push messages. +2. When a message arrives, ntfy broadcasts an Android Intent (`io.heckel.ntfy.MESSAGE_RECEIVED`). +3. **Helios Tracker** listens for this broadcast, filters for the configured topic, and checks if the message is `LOCATE`. +4. A `WorkManager` job gets the current location (WiFi/cell-based, ~100m accuracy) and battery level. +5. The result is sent back via HTTP POST to a configurable ntfy reply topic. + +## Server-Side Usage + +### Send a LOCATE command + +```bash +# Simple curl — send "LOCATE" to your listen topic +curl -d "LOCATE" https://ntfy.sh/YOUR_LISTEN_TOPIC +``` + +### Wait for the response + +```bash +# Subscribe and wait for the next message on the reply topic (blocking) +curl -s "https://ntfy.sh/YOUR_REPLY_TOPIC/json?poll=1&since=30s" +``` + +### Full example: locate and get response + +```bash +#!/bin/bash +LISTEN_TOPIC="my-device-locate" +REPLY_TOPIC="my-device-reply" + +# Subscribe in background, wait for one message +curl -s -m 60 "https://ntfy.sh/$REPLY_TOPIC/json?since=now&poll=0" > /tmp/location.json & +LISTENER=$! + +sleep 1 + +# Send LOCATE command +curl -s -d "LOCATE" "https://ntfy.sh/$LISTEN_TOPIC" +echo "LOCATE sent, waiting for response..." + +# Wait for the listener +wait $LISTENER + +# Parse the response +cat /tmp/location.json | jq -r '.message' +# Output: Lat: 52.5200, Lon: 13.4050, Battery: 72% +``` + +### Python example + +```python +import requests +import json +import time +import threading + +LISTEN_TOPIC = "my-device-locate" +REPLY_TOPIC = "my-device-reply" + +result = {} + +def listen(): + r = requests.get( + f"https://ntfy.sh/{REPLY_TOPIC}/json", + params={"since": "now", "poll": "0"}, + stream=True, timeout=60 + ) + for line in r.iter_lines(): + if line: + msg = json.loads(line) + if msg.get("event") == "message": + result["location"] = msg["message"] + return + +# Start listener +t = threading.Thread(target=listen) +t.start() +time.sleep(1) + +# Send LOCATE +requests.post(f"https://ntfy.sh/{LISTEN_TOPIC}", data="LOCATE") +print("LOCATE sent, waiting...") + +t.join(timeout=60) +print(result.get("location", "No response")) +# Output: Lat: 52.5200, Lon: 13.4050, Battery: 72% +``` + +### Home Assistant example (REST command) + +```yaml +# configuration.yaml +rest_command: + locate_phone: + url: "https://ntfy.sh/my-device-locate" + method: POST + payload: "LOCATE" +``` + +### Node-RED example + +Send a `msg.payload = "LOCATE"` to an **HTTP Request** node configured as POST to `https://ntfy.sh/YOUR_LISTEN_TOPIC`.
