This script creates a Binary Sensor in Home Assistant, which activates during a Red Alert in specified locations. Features include:

• Customizable list of places: Edit homeCitiesTf with a comma-separated list (whitespace tolerant). It can be a single place or multiple.
• Alert window: Set to the past 5 minutes by default (modifiable in thresholdMin).

Installation:

1. Open the File Editor and navigate to configuration.yaml.
2. Copy and paste the contents of this gist into the file.
3. Reload Entities: Go to Developer Tool, select YAML tab and click REST ENTITIES AND NOTIFY SERVICES and TEMPLATE ENTITIES

Important Notes:

• It is not recommended to decrease the scan_interval to avoid the risk of being blocked by the service.
• For cities with multiple zones (e.g., Ashdod A, B, C, D), note that this script does not differentiate between these sub-areas
