MeshMonitor v3.4.4 enhances the Channel Database feature with priority-based ordering and name validation for server-side decryption.
Drag-and-Drop Priority Ordering
Channel Database entries can now be reordered using drag-and-drop. This controls the decryption priority - when multiple channels could potentially decrypt a packet, only the first matching channel in sort order will be used.
Why This Matters
- If multiple channels share the same PSK, the order determines which channel name is associated with decrypted packets
- Higher-priority channels (earlier in the list) are tried first during decryption
- Reduces unnecessary decryption attempts by trying likely channels first
Enforce Name Validation
A new Enforce Name Validation option ensures that a channel only decrypts packets that have a matching channel hash. This is useful when:
- Multiple channels share the same PSK (e.g., default keys)
- You want packets attributed to the correct channel name
- You're monitoring networks where channel naming conventions matter
Note: If the sending device doesn't include channel hash information in packets, enabling this option may prevent decryption even with a valid PSK.
