# System

- [Version & Status](https://docs.encedo.com/hem-api/reference/api-reference/system/version-and-status.md): Two endpoints to gather general information about the device.
- [Checkin](https://docs.encedo.com/hem-api/reference/api-reference/system/checkin.md): Those endpoints perform check-in procedures, a'ka firmware verification and setup of RTC based on trusted data.
- [Configuration](https://docs.encedo.com/hem-api/reference/api-reference/system/configuration.md): These operations allow the read and update of the device configuration. This section includes Secure Enclave provisioning (on Encedo PPA only and during manufacture only).
- [Upgrade](https://docs.encedo.com/hem-api/reference/api-reference/system/upgrade.md)
- [Firmware](https://docs.encedo.com/hem-api/reference/api-reference/system/upgrade/firmware.md): These operations allow the device firmware to be upgraded by uploading a new firmware image over API. This includes integrity and signature validation allowing only a legitimate firmware to be install
- [Low level USB mode](https://docs.encedo.com/hem-api/reference/api-reference/system/upgrade/firmware/low-level-usb-mode.md)
- [Management app](https://docs.encedo.com/hem-api/reference/api-reference/system/upgrade/management-app.md): These operations (on Encedo PPA only) allow the build-in management application to be upgraded. This includes integrity and signature validation allowing only a legitimate application to be installed.
- [Reboot](https://docs.encedo.com/hem-api/reference/api-reference/system/reboot.md): This operation reboots the device, effectively invalidating all issued access tokens (JWT\_TOKEN).
- [Shutdown](https://docs.encedo.com/hem-api/reference/api-reference/system/shutdown.md): This operation shutdown the device, effectively stopping API and securing the chip in a safe state.
- [Self-test](https://docs.encedo.com/hem-api/reference/api-reference/system/self-test.md): This operation performs an internal full self-test of the device's critical components, including cryptography primitives, random number generator and key repository integrity.
