## About the product

4FG Smart Gas Monitor is a connected LPG cylinder monitoring system for households and commercial users that measures cylinder weight from a base placed under the cylinder and shows live gas levels in an app and web dashboard.

Key capabilities include:

- **Real-time gas level readings** that display cylinder **percentage** and **estimated kilograms** so users can check remaining gas without shaking or lifting the cylinder
- **Low-gas alerts** with **user-set thresholds**, so notifications arrive before cooking is disrupted
- **Usage analytics** that track daily consumption and refill patterns to support planning for homes, facilities, and restaurants
- **Refill ordering through a verified vendor marketplace**, including **transparent pricing**, **delivery tracking**, and **in-app payment**, plus the option to **auto-reorder** when gas drops below a threshold or require **user approval** before placing an order

Available via a **web portal** and **mobile app** (Android and iOS are mentioned on the website are still under testing).

Target users include **households**, **facilities**, **restaurants**, and **LPG vendors** that want a connected way to monitor cylinders and coordinate refills.

Notable for combining **weight-based monitoring** that works with **common existing cylinders without valve modification** and an **approved vendor marketplace** that keeps level tracking, ordering, and delivery status in one flow.
