Build your own tab with live readouts and an action button
An app extension is a web page that opens as a tab in the desktop app. Build one that watches a battery pack's weakest cell and sets its alarm threshold with an action button.

Build an extension for your own instrument
Create an agent extension in the app, stream your instrument's readings, run its action, and change the code with a stop and a start.

Connect your hardware's protocol without writing code
Extensions connect the agent to your bench's interfaces. Install one from the marketplace, configure and start it, and plot its signals live.
4 min
Find your way around the app
A tour of the desktop app in the order you meet it: Home, data sources, Explorer, tabs and panels, the timeline, traces, layouts, and the sidebar views.

Write your first notebook and chart live signals
A notebook is a markdown file with Python cells. Make one, chart a battery pack's cell voltages from live data, and open the plain file it saves.
3 min
Run bench tests with pytest and open the failure
Check live signals from pytest, read which sample broke the rule, and open the failing test's trace in the app.
2 min
Install the CLI
Install the Zelos CLI with one line, see what it does from a terminal, and start simulated data so you can follow the other guides without hardware.
3 min
Keep extensions running, and find out why one stopped
Read the extension icons, trace a stopped extension to one line in its log, fix the setting and restart it, and update or remove extensions.
3 min
Pause live data, measure a change, and compare two runs
Freeze a live view on one moment, read every panel there, measure a change, then save the run and lay it over an earlier one.
3 min
Pick the right panel for each signal
Choose a panel by the shape of the signal: a plot for a value that moves, state bands for a value that holds, a large readout, or a log.
3 min
Publish a notebook your team can read
Publish a notebook with its outputs to Zelos Cloud, add the next version, choose who can open it, and let a teammate read and copy it.
2 min
Record a trace file from your own Python script
Write a .trz trace from your own Python script, save the minutes before a fault, and open the file in Zelos.
3 min
Re-run a notebook on a new time window
Change a notebook's time window from the sidebar, run it again with Run all, and re-run only the changed cells with Run out-of-date cells.
3 min
Build a view once and reuse it on every run
Save your panels and tabs as a layout, then load it on any recorded trace to get the same view in one click.
2 min
Define your data's units and states up front
Give your signals units, types and named states once, from a file such as a DBC or from your own code, and every panel in Zelos shows them.
3 min
Run actions on your bench from the app
Find an action in Explorer, run it from an Action panel, watch the plot answer, and read a PASS or FAIL verdict. A short script stands in for the bench.
2 min
Stream your own measurements with the SDK
Stream readings from your own code into Zelos with the SDK and plot them live, on one timeline with the rest of your data.
3 min
Turn a notebook into a pass/fail test
Add rules to a notebook, see every result with the sample that proves it, and make one failing rule fail the whole run.
3 min
Write your own action in Python
Turn a Python function into a button in the app: a typed form, a result, a pass or fail verdict, and the same call from your own scripts.
