Home Assistant energy checker

Check an entity's Energy role, device class, state class, and unit against Home Assistant rules. Results stay local and still require recorder checks.

NFS firewall planner

Plan source-scoped NFSv3 or NFSv4 host-firewall listeners for firewalld, UFW, or nftables. Verified helper ports are required for NFSv3.
