Helix-Platform/Sandbox ? reverse-engineered prompt

Build me a Helix Sandbox style backend for smart environment and IoT projects, with an easy setup and a simple web dashboard for installing, configuring, and managing the main components. I want it to help people spin up a working sandbox for things like context management, data collection, and historical storage, so they can test smart city or smart building ideas without needing a huge infrastructure.

It should support the common IoT flows I’d expect here, like exposing and managing context data with NGSI LD style APIs, and working with devices and sensors over protocols like MQTT, CoAP, and HTTP. Make it feel practical for a proof of concept or MVP, so it runs well on limited resources and can be deployed in different environments.

Please include a clean way to start and stop the services, basic docs for setup and common tasks, and a few example requests so I can quickly see how to use it. If you need current docs for any of the related components, look them up online.
