Replay
Play back what this device recorded, including what the cloud holds for it. Pick a time window, tick channels, press play.
On the scrubber:
- faint bands show where data exists
- the brighter segment is what the charts show
- the dot is the playhead
The status row below shows window (how much history is loaded) and showing
(how much of it the charts draw). Zooming changes showing, not what is loaded.
The time control starts at All history, showing the last hour. Pick a recording, a date or a quick range (Last 5m, …) to move. A relative range keeps following the newest data until you pick a fixed one.
Finding channels
Press / (or ⌘F) anywhere on the screen to search channels. Chips below the search narrow the list. Each chip shows how many channels it would leave; a chip at zero is disabled.
| Facet | Choices |
|---|---|
| kind | all · signals · cameras · 3d |
| activity | in window (has data in the loaded window; the default) · all |
| source | one chip per source prefix, e.g. mav, daqmx |
| unit | one chip per unit suffix, e.g. deg, rpm |
Filters combine. Picking several sources or units shows channels matching any of them. clear (n) resets them. Filters last only for this session.
Unit chips read the unit from the channel name
(/arm/joint/position_deg → deg). A channel with no unit at the end of its
path appears under no unit chip, whatever unit it was given.
The header's Find moments… box is different: it searches camera footage by description and pins each match on the scrubber.

When the screen opens empty
Right after launch, history can take a moment to load. The screen retries on
its own and shows retrying (3 of 10); Try again starts another round. It
shows No history yet only once the device confirms it is healthy and holds
nothing. An unpaired device shows a local chip: real history, nothing synced
to the cloud yet.
