How so? It's a really obvious approach these days. Doing it this way provides a web-accessible front-end and the actual hardware may be something compact like a tablet, phone, headless SBC, etc. (whatever can provide BT and promisc. wifi basically)

The web offers a fairly universal cross-platform, network-accessible GUI that can be developed with really high-level languages which happen to offer tooling that includes an extremely-empowering degree of readily-available utility libraries. What other language or ecosystem is as easy and broadly-accessible?
