[MS#2 AQ] Discovery

[glossyio]

Story

As a developer, I want to review software libraries, examples, and projects that currently exist, so that I can understand what's possible and what's already been developed that we can utilize.

Definition of done

• Create a comprehensive list of projects and applications that may be applicable
• Come back with an approach for implementing the MVP AQ metrics
• Document potential future possibilities
• Update docs with payloads (potential)

References

• See Pimoroni/enviroplus-python User Projects

roscoe81/enviro-monitor

https://github.com/roscoe81/enviro-monitor

Comparisons relative to the base pimoroni/enviroplus-python repo

Pros/Good

• Implements internal logging capability for internal compensation
• Implements and utilizes mqtt communications
• Improved Gas sensor metrics: compensates for temp, humidity, air pressure; also has time-based drift (requires altitude config input)
• Implements a Noise Measurement setup for the microphone
• OLED Display updates

Cons/Missing

• Single, large Python file is going to require slicing and dicing
• Many components are related to third party systems such as Lufdaten and Home Manager, which we will not be using

tijmenvandenbrink/enviroplus_exporter

https://github.com/tijmenvandenbrink/enviroplus_exporter

Comparisons relative to the base pimoroni/enviroplus-python repo

Pros/relevant

• Builds a Docker container; having everything containerized would avoid system dependencies! Pass-through for senors using --device switch

Cons/irrelevant

• Prometheus is a very cool addition, but we won't have need for this since we're using ThingsBoard
• InfluxDB [Cloud] used to record measurements; although enticing, we are storing values in SQLite in Node-RED
• Code mostly in-line with base, pimoroni repo
