change messages to use MQTT-SN #15
Description
Story
To adopt a more standard communication format, I should convert all external facing messaging to MQTT-SN, a industry staple.
Background
I wanted to adopt a particular format to standard my messages and stumbled upon MQTT. There is a lot of support for MQTT in the IoT industry (openhab, AWS/Azure IoT hubs etc all work with MQTT formats). The -SN variant is for Sensor Nodes and supports communication over non TCP stacks (such as RF).
Acceptance Criteria
- That each possible externally facing message (e.g. serial msg on Arduino) passes an MQTT-SN validator
