Receive fake IoT device message via AWS

[iamnwi]

Assumptions:

• Use AWS Cloud IoT Service and MQTT
• Write fake IoT device script in python
• The simulated device send message to AWS
• Our app server pull message from AWS

[iamnwi]

I set up a new project for this IoT feature. In this way, we can avoid re-deploying all components of our App every time a single component is changed. IoT feature project here: https://github.com/NYUCC2020/ExpenseTrackerIoT

What I have did:

1. Deployed a MQTT server for our APP
2. "Home Device" topic messages sent to our MQTT server will be forward to AWS IoT
3. Deployed a "Home Device" topic Subscriber that collects and processes all home device messages and then store them to our DB
4. A simple fake-device script to publish "Home Device" topic message to our MQTT server
5. Deploy this feature into K8s using Continuous Delivery(Build and Deploy whenever there're changes)

Upcoming:

1. Improve and deploy the fake-device script to the Cloud so that it publishes "Home Device" topic messages to our MQTT server periodically

Need help:

1. We need to device_id for such device that sending message to our MQTT. Now I just pick one for the fake-device. However, we need to set up a way to map device_id with user_id so that user can and only can see their device data
2. A UI to visualize the device usage data
3. A UI to let user register their device(pick device_id by themselves)
