The Web in an Era of Smart Devices
summary
The web today connects to smart devices using Web Bluetooth (BLE central only, HTTPS + user gesture) to change a bulb’s color and read a Polar heart‑rate belt, and Web USB to enumerate a USB‑powered board, read a temperature sensor and drive RGB LEDs from JavaScript. Progressive Web Apps plus service workers and HTTP/2 server push make one‑time or frequently used device UIs fast and offline. NFC (write “milk” to a tag), Eddystone Physical Web beacons, and the Generic Sensor API are available behind flags or in Chrome with platform caveats.
