🛴 E‑Roller Auto-Power-Off Script (Home Assistant)

This automation ensures that your electric scooter charging outlet is safely turned off once charging has completed – based on power consumption. It also notifies you immediately when charging is done.

⚙️ What It Does

The automation continuously monitors the power draw of the scooter’s outlet. If the draw drops below 17W for more than 5 minutes, it:

• Turns off the power outlet (e.g., Shelly, Zigbee plug, etc.)
• Logs the event to the Home Assistant Logbook
• Sends a push notification to your phone
• Works even after Home Assistant restarts
