Digi IoT Device Simulator review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

For developers working with Digi Remote Manager, Digi IoT Device Simulator is a desktop command-line application for creating simulated device fleets without physical devices. It runs on Windows, macOS, and Linux, and supports Digi ConnectCore-based devices. Its role is focused: it lets teams exercise device behavior in Digi Remote Manager rather than offering a general-purpose simulator for unrelated platforms.

Simulation controls cover firmware-update successes and errors, maintenance windows, scheduled or random disconnections and reconnections, data sampling and uploads, and device-request behavior. The tool also provides interactive simulated device file systems. Python supports custom request handling and generated data, while samples and reusable templates can serve as a starting point for custom simulations. That combination suits development and validation workflows where device behavior needs to vary, but the target environment remains Digi Remote Manager.

Digi distributes the application as a downloadable package and it is classified as free. According to the simulator documentation, the default maximum is 200 simulated devices; larger simulations require contacting a Digi sales representative. The narrow platform fit and documented scale boundary make it most suitable for teams already building around Digi devices and Remote Manager. Teams needing a simulator for other device ecosystems, or fleets beyond the default limit without a sales discussion, should consider alternatives aligned with those requirements.

Digi IoT Device Simulator pros and cons

• Where it wins
  • Simulates device fleets without physical hardware
  • Configures firmware outcomes, maintenance windows, and connectivity changes
  • Supports Python custom code, reusable templates, and simulated file systems
• Where it doesn't
  • Focused on Digi Remote Manager and Digi ConnectCore-based devices
  • The documented default limit is 200 simulated devices
  • Larger simulations require contacting Digi sales
