GaugeLens AI — Demo video

In Lagos, the inverter keeps the lights on, but nobody's watching it. AI can read its display, but it can be wrong with total confidence. GaugeLens turns a phone video or photos of a digital display, such as an electricity meter, water meter, inverter, or multimeter, into readings you can check. SAM 3.1 finds and tracks each display. Muse Spark reads the digits and identifies the equipment from its printed label. Physics rules then test the readings: energy never goes down, real power can't exceed apparent power, and flow can't exceed the limit on the label. When a reading breaks a rule, SAM 3.1 boxes the digits; they're read again, and the correction is accepted only if it fixes the rule. If a reading can't be proven, it's marked for review rather than guessed. An agent answers questions with cited evidence, and every step is visible in a trace. GaugeLens never touches equipment: it proposes a safe check, and a person approves or rejects it.
