Simulator for Smart Factory Lighting

Overview

The simulator is programmed in Node-Red environment. To run the environment, you need to install Node-Red (basically a nodeJS-based programming tool) and import the simulator_flow.json.

Steps

1. Install Node-Red by following this installation guide.
2. Start Node-Red:

node-red

3. Open the Node-Red editor by visiting http://127.0.0.1:1880/ in your browser.
4. On the top-right drop-down menu, select Import, and upload simulator_flow.json to import it.
5. Deploy the simulator flow by selecting Deploy.
6. The status endpoint is http://localhost:1880/was/rl/status, and you can also interact with the simulated environment via this Postman Collection. Example response:

{
  "Z1Level": 396.3840986447821,
  "Z2Level": 473.1920493223911,
  "Z1Light": false,
  "Z2Light": true,
  "Z1Blinds": true,
  "Z2Blinds": false,
  "Sunshine": 640.1482750972317,
  "TotalEnergyCost": 15,
  "EnergyCost": 0,
  "Hour": 1.5000000000000002
}

7. To send and action to the environment, POST the action as json payload to http://localhost:1880/was/rl/action For example, to switch on the Z1 Lights:

{

  "Z1Light": true

}

The response will confirm your action and provide a cost:

{

  "Z1Light": true,
  "cost": 100
}

The simulator increments the time (Hour) by 0.1h every second and computes the new state of the environment. To keep things simple (intially), the Sunshine value hovers around 600..650. If you want to play with this, look at lines 11..20 in the "Update environment" node.
