Monitor Temperatures and Act on Excursions

We log fridge temperatures on a clipboard and nobody notices when one is wrong. Build me a temperature monitoring app. Keep units as records with their location, what they hold, the acceptable minimum and maximum, and the reading frequency required. When a reading is entered on a phone, check it against that unit range immediately and, if it is out, create an excursion record capturing the reading, the time it was detected, the duration until it returned to range, the action taken and any decision about the product affected. Show readings per unit over time as a trend rather than only as a list. Add an AI agent that reviews the readings and tells me which units are drifting toward their limits and likely to fail soon, which have the most excursions, and where a pattern suggests a door left open rather than an equipment fault. Automate three things: a reminder when a reading is due, an immediate alert on an out-of-range reading, and a scheduled weekly report of excursions and units trending badly. Two logins: staff who take readings, and a manager who sees trends and closes excursions.
