Smaz Decompression

Meshy can decompress incoming messages that use Smaz text compression:

• Some MeshCore clients (e.g. meshcore-open) compress outgoing messages using the Smaz algorithm and send them with an s: prefix.
• Meshy automatically detects and decompresses these messages.
• Meshy does not compress outgoing messages — for the typically short MeshCore messages, the encoding overhead negates the compression savings.

Trip Time Tracking

Every delivered message includes round-trip time (RTT) measurement:

• Timer starts when message is queued for transmission.
• Timer stops when ACK is received.
• Displayed in milliseconds next to the ✓✓ status.
• Useful for diagnosing network latency and hop delays.

SNR Visualization

Signal-to-Noise Ratio (SNR) indicates link quality:

• Green (≥0 dB) -- Excellent signal.
• Yellow (-5 to 0 dB) -- Marginal signal.
• Red (<-5 dB) -- Poor signal.

SNR is shown in:

• Path traces (color-coded labels on map).
• Neighbor lists (repeater management).
• Rx Log entries.

Cayenne LPP Telemetry

Meshy fully supports the Cayenne Low Power Payload format for sensor data:

• Digital/analog I/O.
• Temperature, humidity, pressure.
• Accelerometer, gyrometer.
• GPS coordinates.
• Battery voltage and current.
• Luminosity, presence detection.
• And 20+ other sensor types.

Telemetry is decoded automatically and displayed in human-readable format.

Packet Deduplication

Meshy maintains a rolling buffer of the last 32 received packet hashes:

• Prevents duplicate processing when packets arrive via multiple paths.
• Hash is computed from packet contents.
• Duplicates are silently dropped.
• Useful in dense mesh networks with many redundant paths.
