## Summary

This project contains a system in which Node-RED is used to turn any Windows-based PC on and off using

python and a TCP connection. To do this, the following systems are needed:

- Smart Home Agent (Alexa, Google Home)

- [Windows Task Scheduler](https://docs.microsoft.com/en-us/windows/win32/taskschd/task-scheduler-start-page)

- [Node-RED](https://nodered.org/)

## Architecture

The system works by using a Raspberry Pi as the central control system running NodeRed in Docker. This Raspberry Pi then

communicates with other Smart Home devices such as alexa and then the Windows PC running the Sleep on LAN script. The

architecture of the system is shown below:

![System Architecture](docs/System%20Architecture.png)

The Task Scheduler in Windows is used to run the Python script, which is waiting for a TCP socket connection and then

once it receives the correct command, it will put the computer to sleep. Task Scheduler is used because it

allows the python script to run and handle starting it on boot.

## Node Red Flows

Inside Node-RED, there is the following flow which uses both Telegram and Alexa Nodes; the reason is for this is that.

The desk where the computer is connected has its own smart plug for the monitors. When the PC is turned off and on,

the monitors also need to be turned on and off.

![Node-RED Flow](./docs/NodeRED%20Flow.png)

The PC is registered as an Alexa device using the node-red-contrib-alexa-home-skill node, which feeds a function for

the turnOn and off requests. This then sends the appropriate command to the sleep on LAN script as well as the wake on

LAN node provided by Node-RED.

## Software Requirements

The following pieces of software are required for the system to work:

- [Node-RED](https://nodered.org/)

- [node-red-contrib-telegrambot](https://flows.nodered.org/node/node-red-contrib-telegrambot)

- [node-red-contrib-alexa-cakebaked](https://flows.nodered.org/node/node-red-contrib-alexa-cakebaked)

- [Windows Task Scheduler](https://docs.microsoft.com/en-us/windows/win32/taskschd/task-scheduler-start-page)
