💡 Features

Customer

1. A customer can submit new meter readings, which consists of four parts:
   • Submission date (e.g. 2022-11-05, default value: today)
   • Electricity meter reading - Day (e.g. 100 kWh)
   • Electricity meter reading - Night (e.g. 250 kWh)
   • Gas meter reading (e.g. 800 kWh)
2. A customer can view and pay the latest unpaid bill with energy credit.
3. A customer can top up the credit with a valid EVC*.

Admin

iGSE admin account: there is only one pre-defined GSE admin account (due to requirement), which has a login name “[email protected]” and a default password “gse@energy”.

1. Admin can set the price per kWh (or unit cost) for the electricity (day/night) and gas.
2. Admin can access meter readings submitted by all customers.
3. Admin can view the energy statistics– show the average gas and electricity consumption (in kWh) per day for all customers based on their latest billing period.

System

• Integration of QR code scanning for easy registration and verification of energy vouchers.
• REST API endpoints to provide open access to energy consumption data and statistics.
• Robust error handling mechanisms for providing meaningful error messages.
