Telemetry That Keeps Its Shape
A codec that reads the shape of sensor streams · zpe-iot 0.1.1 · PyPI · github.com/Zer0pa/ZPE-IoT
An accelerometer on a robot arm traces a smooth curve. A GPS tag follows a path. A pressure sensor rises and falls on a schedule. General compressors don't see any of that — they treat sensor data as bytes.
ZPE-IoT reads the shape underneath: 6.83× mean compression across ten real sensor datasets, ten wins out of ten against zstd's 2.87×. DS-12 stays on the page too — zstd 5957× to our 120× — disclosed and named.

Sensor streams carry a shape. general-purpose codecs see only bytes — they don't read it.
Sensor data has a shape. a codec can read it.
Sensor telemetry moves through MQTT, Kafka, or SparkplugB and gets squeezed by zstd or gzip on the way. Lossless baselines see bytes — not the smooth curve of an accelerometer, the arc of a GPS path, or the rhythm of pressure.
ZPE-IoT reads the signal type — accelerometer, GPS, pressure, voltage — and encodes around its shape. The codec is bounded-lossy: it keeps what matters in a smooth trajectory and discards the rest. 6.83× mean compression across ten real sensor datasets. Ten wins out of ten against zstd's 2.87× baseline.
Ten datasets carry the wins. DS-12 sits beside them.
The codec commits what it can read. DS-12 proves the limit.
ZPE-IoT commits deterministic encode/decode tests for the codec surface — not broker transport or downstream IoT-stack behaviour. DT-03 verifies 10,000-seed determinism, DT-11 verifies cross-platform parity, and DT-09 holds 0.031 ms native encode latency.
DS-12 is a different question. On that dataset a competitor codec reads the shape better: zstd reaches 5957× and ZPE-IoT reaches 120×. The win surface stays DS-01..DS-10, with DS-12 disclosed outside it on every page that reports the numbers.
DS-12 is a transparent competitor win — zstd 5957.82× against ZPE-IoT 120.47×. DS-11 is blocked. PyPI 0.1.1 sits stale pending the next release. No production MQTT, Kafka, or SparkplugB bridge is claimed yet — only the codec itself ships.
WHEN TELEMETRY keeps its shape.
The ambition is sensor transport that understands what it carries. An engineer running a fleet of accelerometers, GPS tags, and pressure cells should get encoding that reads the stream rather than guessing at the bytes. DS-11, a production broker bridge, and a clean release stand between today and that fleet.
