Display YouTube Subscriber Count on Ulanzi AWTRIX Smart Clock

Description

Overview:
This n8n workflow fetches the subscriber count of a specific YouTube channel using the YouTube Data API and displays the compacted count on an AWTRIX 3 / Ulanzi Smart Clock via its local HTTP API.

💡 You can run this every hour (or adjust the schedule), and it pushes a custom notification with a YouTube-style icon to your AWTRIX screen.

🔧 Setup Instructions:
1. 🧩 Requirements
A working AWTRIX 3 (e.g., Ulanzi Smart Clock) on the same local network.
A valid YouTube Data API v3 key.
A channel ID for the YouTube channel you want to track.
Upload a YouTube-style icon to your AWTRIX before running this flow:
Go to AWTRIX Icon Gallery
Search for a YouTube icon or upload your own
Get the corresponding icon ID (e.g., 26963)

2. 🧠 How It Works
Triggers every hour
Makes a GET request to YouTube API to fetch subscriberCount
Formats the number using compact notation (e.g., 1.2M)
Sends a POST request to AWTRIX at your specified local IP with the count and icon

3. 🔧 Required Replacements:
