That would defeat the object of building a Web of Things gateway. The purpose of the gateway project is to bridge non-web and non-Internet devices to the Web of Things using HTTP and WebSockets. One of the requirements being that it should still work locally without an Internet connection. The gateway therefore has to act as a web server.

You could certainly build an IoT gateway which bridged those devices to MQTT instead, and even have an MQTT cloud service which then proxies those devices to the Web of Things. But that isn’t this project.

The gateway software is not intended to run on the kind of low end hardware found in traditional home routers, but it could run on a “smart router” which has a lot more processing power and RAM.
