Potential configuration pitfalls

[oscgonfer]

Opening this issue to document potential configuration pitfalls (to cascade into issues later on)

1. Device role: ideally CLIENT, CLIENT_MUTE or SENSOR -> test use cases. Can there be other roles (eg ROUTER)?
2. Data packets: avoid sending data packets to phone only for Smart Citizen use case. We always want to make sure data reaches our server either via MQTT or mesh.
3. RTC: measurements can take place even without timestamp as it will be assigned on the node that received it (if a node has timestamp, probably has uplink too). A node without timestamp, however, shouldn't be allowed to uplink non-timestamped points, unless we have a timestamp on ingestion
