Where you'd use it
Freezer and fridge safety monitoring
Run the 1 metre probe into a chest freezer or fridge to get an alert the moment the temperature drifts outside a safe food-storage range.
Heating system flow tracking
Clip the probe to a hot water cylinder or heating pipe to feed real flow temperature into a heating automation rather than relying on a room thermostat alone.
Aquarium heater control
Submerge the probe in a fish tank and pair it with a Shelly relay so a heater switches on automatically once the reading drops below your set point.
