Node-Red-Flow - These nodes control 4 relays to control 4 applications. It also inputs temperature data and humidity data from the DHT11 sensor and gives its output on a web dashboard.
This is the web dashboard. Here we can see the humidity and temperature data and 4 switches to control the applications. This dashboard is locally hosted by node red.
This tablet is linked with node red server.
Google home nodes - These nodes help us to enable voice assistance. These are linked with the relay nodes so when we say "Ok Google, turn on switch 1" it enables the relay to trigger the relay1 on.
Room lights are linked with the google assistant and ready for voice control.
