The signals that count

Chronic mild dehydration is linked to fatigue, headaches and kidney-stone risk. A smart AI toilet observes urine concentration and colour, voiding frequency across the day and response to activity and climate — passively, every visit.

Turning data into decisions

Passive daily readings replace guesswork with a personal hydration baseline. That is why LUXOSMT builds a personal baseline and surfaces deviations from it, with an explanation you can act on.
