iot-device-simulator

Google Cloud Platform IoT Device Simulator

The following GCP components/services are involved:

Compute Engine (f1-micro machine type)
IoT Core service
PubSub service

Prerequisites

GCP user account with necessary permissions
gcloud command installed and properly configured

Getting Up and Running

Open a terminal at the project root:

Set environment variables in .env file (see .env.example).
Run ./gcp-init.sh --confirm to perform GCP infrastructure initial setup.
Run ./create-iot-device.sh with optional device ID argument, e.g.:
```
$ ./create-iot-device.sh my-device
```
by default GCP_DEVICE_ID value from .env file is used.
Run ./run-iot-device.sh with optional device ID argument, e.g.:
```
$ ./run-iot-device.sh -d my-device
```
by default GCP_DEVICE_ID value from .env file is used.

To be able to run device simulator in a background mode an extra optional argument -b can be added:
```
$ ./run-iot-device.sh -d my-device -b
```
You can run multiple instances of the device with different device ids.
```
$ ./run-iot-device.sh -d my-device-1 -b
$ ./run-iot-device.sh -d my-device-2 -b
```

TODO

Add ability to run fake iot device in a background
Use Docker containers to ship python code
Use API calls instead of using gcloud (someday)
Create Web application to manage fake iot devices (someday)
