ondotori-ble

Unofficial alpha

This project is independent of T&D Corporation. It supports selected published advertisement layouts and does not yet cover every T&D BLE mode.

ondotori-ble receives current-value manufacturer advertisements from T&D Ondotori data loggers. Its public surface consists of immutable readings, pure packet decoders, synchronous and asynchronous one-shot reads, and a managed async stream for servers.

from ondotori_ble import read_all

for reading in read_all(duration=75):
    print(reading.serial_number, reading.measurements)

Deliberately narrow scope

The library reads BLE broadcasts only. It does not change logger settings, pair, download stored recordings, access WebStorage, or communicate over sub-GHz radio, optical, USB, LAN, or a base-unit bridge. It contains no CLI.

Current support

Device or family	Result
TR41, TR42, TR45	Published temperature decoder
TR41A, TR42A	Published temperature decoder
TR43A, TR32B	Published temperature/humidity decoder
Observed family C3	Raw packet with model deliberately unassigned
Other RTR500B, TR-7wb, TR7A, and TR7A2 BLE layouts	Retained raw until verified
RTR models without a trailing B	Outside the BLE boundary

Evidence and decoding are separate

Every Reading reports protocol provenance through evidence:

Value	Meaning
published	The mapping and conversion appear in a public T&D source.
observed	A byte pattern was independently observed but is not fully identified.
unknown	No verified interpretation is assigned.

reading.is_decoded independently reports whether typed measurements were produced. An observed or recognized packet can therefore remain raw-only.

Start with the quick start, review the exact protocol boundary, and use the reliability guide for long-running services.
