Making errors easy to detect (and fix)

Anyone who has worked with telematics data knows that the real challenge isn’t just connecting sensors or devices. It’s keeping flows clean and reliable as they grow more complex. A missing output, a dangling branch, or an accidental duplicate can break things in subtle ways. And in the past, tracking those mistakes down felt like searching for a needle in a haystack.

That’s why our IoT Logic team built something deceptively simple but incredibly powerful: error detection that actually shows you what’s wrong, where it happens, and how to fix it.

From “flow invalid” to “here’s the problem”

Previously, if a flow was misconfigured, IoT Logic would just say “flow invalid.” Helpful? Not really. Users had to comb through every node to figure out what went wrong. Now, errors are presented differently:

• The problematic node is highlighted in red
• A tooltip explains the issue in plain terms
• All errors appear at once when you try to save, so you can correct everything in one go instead of chasing them down piecemeal

It’s the kind of change that feels small, but it makes the whole experience smoother and much more human.

Say you’re setting up a flow to monitor fuel levels. You connect your Data Source, add a condition for “sudden drop,” and create two branches: one for the alert, one for normal reporting. But in the rush of building, you leave one branch unconnected.

Before, you’d only see “invalid flow.” Now, IoT Logic tells you exactly what’s missing: “Branch has no output.” The node is lit up in red, and the tooltip nudges you toward fixing it. The same goes for more subtle issues – like accidentally wiring the same data path twice, which could cause duplicate messages.

In practice, that means no guesswork, no long debugging sessions. Just a clear path to correction. In other words: the simplicity isn’t just in building flows, it’s in fixing them too.

Simplicity that scales

IoT Logic has always been about making telematics integrations accessible without heavy coding. With error detection baked into the canvas, the platform now goes further – letting teams build with confidence, experiment freely, and ship flows that just work.

It’s not glamorous, but it’s the difference between fighting your tools and having them guide you. And when your business depends on data moving reliably from devices to dashboards, that difference is everything.
