No one wants to be the maintenance worker who has to hike through half a mile of damp hallways just to check the pressure gauge on a valve somewhere. LiLz makes it possible to keep an eye on such inconvenient physical interfaces remotely with a clever and practical application of machine learning.

The Japanese (specifically Okinawan) startup has been around for a little while — in fact our colleagues at TC JP have written them up. But despite the seemingly obvious value of its service, it hasn’t quite hit the big time yet. LiLz participated in CES as part of the country’s trade group, along with a bunch more companies listed here.

LiLz’s device looks a bit like a chubby tablet without a screen. It’s essentially a camera, light and processing and communications chips packed in with a big battery — enough power to last up to three years.

You mount the device so it can see the gauge or dial in question. After confirming picture and signal, you configure it in the app to interpret what it’s pointed at; it can read circular, semicircular and linear gauges, digital and rolling or analog digit displays, or things like colored warning lights.

Once it’s set up, it’ll send readings live or at intervals to a central dashboard, or make them available via API so they can be queried or recorded elsewhere. The data goes out via LTE or Bluetooth.
