EPIC: NFC/RFID integration

[mplogas]

In order to track spools (and to prepare for a Spoolman integration) additional spool information such as vendor, material, color etc could be stored on an RFID/NFC sticker that is added to the spool and read once the spool is weighted. Requires some changes to the JSON de/serialization, MQTT client and 3D models

information that needs to be stored on the tag:

• spool id
• manufacturer (name or id) - for UI
• material (name or id) - for UI
• spool weight in grams

information that could be stored on the tag

• name (needs to be size limited!) - for UI
• color
• purchase date / first scan date?

considerations

• spool id and spool weight aren't changing -> tag sector 0, block 1 & 2
• material and manufacturer -> tag sector 1, all data blocks
• name -> tag sector 2, all data blocks
• color as hex ->tag sector 3, block 0
• date -> tag sector 3, block 1
• with a simple REST interface (or a connection to Spoolman) all non-essential data could be pulled via spoolid/tagid
