v0.2.0 - IoT hub introduced

What's Changed

Major, breaking changes across the board to reduce resource utilization and add capabilities.

To upgrade, we strongly recommend you backup databases and completely re-image device to use these features. Database structures have changed, so do not restore the databases without first altering the structure--we recommend you start with a blank slate.

Highlights

We went away from InfluxDB in favor of a SQLite database. This will allow us to avoid the Docker overhead. We found we were not utilizing the Flux language, querying capabilities, and didn't have a use case to need the big-data querying engine.

We went away from Node-RED in a Docker environment and now install Node-RED as a service. The primary motivation here was having system-level access to execute commands from the Node-RED UI, which we intend to be the primary method for users to interact with their device. We wanted to be able to do things like set the system time, create hotspot AP, change WiFi settings, read system-level settings, and more. This was an instance where Docker's isolation system was holding us back.

For our IoT Hub, we went with ThingsBoard after evaluating many options both open-source and closed-source. We are very excited about ThingsBoard's open source nature and ability to provision devices, collect and process data, provide visualizations, and export data for downstream consumption. Anyone can install ThingsBoard by using the Community Edition, using their PaaS Cloud offering, and/or professional edition.
