Smart Home & Automation

Any webhook, one notification

syncfu accepts any HTTP POST on port 9868. If a system can fire a webhook — Home Assistant, Node-RED, IFTTT, Zapier, a cron job, a custom script — it can put a notification on your screen. No SDKs, no configuration files, no accounts.

Home Assistant integration

Add syncfu as a notification target in Home Assistant using rest_command:

# configuration.yaml
rest_command:
  syncfu_notify:
    url: "http://your-desktop:9868/notify"
    method: POST
    content_type: "application/json"
    payload: >
      {
        "sender": "home-assistant",
        "title": "{{ title }}",
        "body": "{{ message }}",
        "icon": "{{ icon | default('home') }}",
        "priority": "{{ priority | default('normal') }}"
      }

# automation.yaml
- alias: "Doorbell notification"
  trigger:
    - platform: state
      entity_id: binary_sensor.doorbell
      to: "on"
  action:
    - service: rest_command.syncfu_notify
      data:
        title: "Doorbell"
        message: "Someone is at the front door"
        icon: "bell"
        priority: "high"

Node-RED flows

Use an HTTP Request node to POST to syncfu from any Node-RED flow:

// Node-RED function node → HTTP Request node
msg.url = "http://your-desktop:9868/notify";
msg.method = "POST";
msg.headers = { "Content-Type": "application/json" };
msg.payload = {
    sender: "node-red",
    title: "Motion Detected",
    body: "Camera: Front yard — " + new Date().toLocaleTimeString(),
    icon: "eye",
    priority: "high",
    actions: [
        { id: "view", label: "View Camera", style: "primary" },
        { id: "dismiss", label: "Dismiss", style: "secondary" }
    ]
};
return msg;

Price drop alerts

Monitor prices on any website with a simple script. Unlike CamelCamelCamel and Keepa (which only track Amazon), this works anywhere:

#!/usr/bin/env bash
# Price watcher — run via cron every hour
TARGET_PRICE=349
CURRENT=$(curl -s "https://api.example.com/price/ps5" | jq -r .price)

if (( $(echo "$CURRENT <= $TARGET_PRICE" | bc -l) )); then
  syncfu send -t "Price Drop!" -p high -i trending-down \
    -a "buy:Buy Now:primary" -a "watch:Keep Watching:secondary" \
    "PS5 dropped to $CURRENT (target: $TARGET_PRICE)"
fi

Cloud billing alerts

# AWS spend check — daily cron
SPEND=$(aws ce get-cost-and-usage \
  --time-period Start=$(date +%Y-%m-01),End=$(date +%Y-%m-%d) \
  --granularity MONTHLY --metrics BlendedCost \
  | jq -r '.ResultsByTime[0].Total.BlendedCost.Amount' \
  | xargs printf "%.0f")
BUDGET=1000

if [ "$SPEND" -gt "$((BUDGET * 85 / 100))" ]; then
  syncfu send -t "AWS Spend Warning" -p high -i flame \
    -a "dashboard:Open Console:primary" \
    "Current spend: $SPEND ($(( SPEND * 100 / BUDGET ))% of $BUDGET budget)"
fi

Crypto and stock price alerts

import requests

# Check Bitcoin price against target
price = requests.get("https://api.coinbase.com/v2/prices/BTC-USD/spot").json()
current = float(price["data"]["amount"])
target = 100000

if current >= target:
    requests.post("http://localhost:9868/notify", json={
        "sender": "price-watcher",
        "title": f"BTC hit {current:,.0f}",
        "body": f"Bitcoin crossed your {target:,} target",
        "icon": "trending-up",
        "priority": "high",
        "actions": [
            {"id": "sell", "label": "Open Exchange", "style": "primary"},
            {"id": "hold", "label": "Hold", "style": "secondary"},
        ],
    })
