Return connection and capture status.

Begin continuous (streaming) capture into a named session.

Returns the session name used. Sampling continues in the background until :func:metashunt_stop_capture is called.

Stop recording. The device keeps measuring; the server just stops listening. The current session is finalized on disk.

Return the most recent samples from the live ring, decimated.

max_points caps the output; the adaptive decimator preserves charge and keeps spike timing. Returns decimated (t_us, cur_ma) plus a summary.

Perform a high-rate device burst read.

trigger: immediate | rising | falling | stage | key2. level: current in uA for rising/falling, or the stage index for stage. Returns up to 37,500 samples at up to 127.5 kHz, decimated for return.

Add/replace a host-side trigger watching the live stream for a crossing above above_ma and/or below below_ma (mA).

List persisted capture sessions (from .npz/.json logs).

Load a session from disk, decimate, and return its data + summary.

Load a time window [start_t_us, end_t_us] of a session on disk.

Compute aggregate statistics (count/mean/std/min/max) over a session window without transferring the full dataset.
