DataGenerator

The DataGenerator application is a utility designed to generate realistic fake data for the Measurements service of the Homee System Server.

It provides a simple WinForms-based UI where users can:

• Choose between 1 and 20 devices.
• Configure each device individually or synchronize settings across all devices.
• Assign custom device numbers.
• Define the date range for the first and last measurements.
• Set measurement frequency (e.g., every 5, 10, or 15 minutes).
• Select the types of measurements each device will perform.

The application generates multiple .json files:

• DeviceNumber.json – Used to register devices in the Devices service.
• Other .json files – Contain measurement data that can be easily imported into CosmosDB for testing or simulation purposes.
