Entity Categories

Home Assistant added entity categorization in 2021.11. Once we implement devices (#13 (closed)), we can mark entities as primary, config, or diagnostic. (See HA developer docs for details.)

Since this is a publish-only project (at the moment), we will probably only use primary entities and diagnostic.

It is unclear if a device can be entirely diagnostic entities. Many plugins (Adaptec HBA, IPMI, lm-sensors, Uptime) typically are just diagnostic data. Hopefully it works 🤞
