Raspberry Pi IoT Server using Express an Sockeio to control and view state.
Three basic parts
app.js and index.html - Raspberry Pi/Arduino Communication via Xbee radios to toggle remote arduino pin
app1.js and index1.html - Raspberry Pi/Arduino Communication via Xbee radios to set state of Neopixel (RGB LED)
app2.js and index2.html - Raspberry Pi communication with relay switch directly connected to Pi... Add xbee radios or similar to put distance between Pi and remote modules
expressjs.com - serve html page to control/view state
socket.io - messages between server (app.js) and client (index.html). Keeps all versions of client insync with state of backend (in memory js object). Is the pin on the arduino high or low (relay, reed, anything open or closed).
serialport.io & npm xbee-api - listen for state of remote xbee radios - fires socket.io.emit to inform clients. Also sends state change request to remote radio.
nginx.com can be used as a reverse proxy listening on 80 and forwarding to port your app is running on (3000 in this example)
dataplicity.io or balena.io can be use to expose port 80 to the world - I use/like both. dataplicity is quicker to get up and running.

See this link to set up your radios in api mode. Then just add the two settings in pic to your router. https://www.youtube.com/watch?v=LgwM6YWz_Fw

Note: this was designed to run on Raspberry PI but could work anywhere you have node installed
cd pi
npm installnpm start
browse to localhost:3000npm run test👤 prichardsondev
