开源的真正力量在于它可以像搭积木一样工作。例如，可视化需要数据，而这些数据需要被储存在某个地方，这些数据也需要被运输。

有很多工具可以使用，例如Eclipse Mosquitto，一个实现了消息队列遥测传输协议（MQTT）的开源消息代理；以及InfluxDB，一个时间序列数据库。所有这些都在Linux上运行，协同工作以构建令人惊叹的交互式工业界面。

再加上易于配置的仪表盘工具，如Grafana或Chronograf；它们都是可扩展的，并且可以从大量使用它们的社区中获得可用的贡献。也许对HMI平台重要的演变是引入了Linux，它提供了一个重要的画布来创建一个多样化和高功能的界面。

那么，如何开始? “如果你已经使用Linux和浏览器实现设备，那么你就可以马上开始了，不需要其他硬件。”万可公司Linux 和 IIoT 应用工程师Jesse Cox说，“安装Node-RED，并开始用一个简单的基于浏览器的集成开发环境（IDE）构建界面。导入仪表板节点以将组件添加到Web用户界面(UI)，你将惊讶于构建交互式UI的速度之快。如果你的HMI有一个浏览器，那么你可以把它指向你的Node-RED实例，然后你可能不会再以同样的方式看待闭源HMI解决方案了。”
