Honest numbers
Most listings say “high accuracy” and stop there. ThermoSense states ±0.5°F and ±3% RH, and includes a card so you can verify it yourself with an ice bath. If your unit is outside spec, we replace it.
Calibrated sensor, verified against an ice-point reference.
Dry / comfortable / humid — readable without knowing the numbers.
Nursery, basement, living room. No hub, no pairing.

Checked all three against an ice bath and a calibrated hygrometer. Two were within 0.4°F, one was 0.8°F off. Good enough for a house. The comfort icon is genuinely useful.
Works as described. The numbers are smaller than I expected and the viewing angle is narrow — from the side it washes out. For the price for three, it’s acceptable.
Finally confirmed the basement is six degrees colder than the living room. That explained a lot about our heating bill. Magnet is strong enough for the fridge.
Two are perfect. The third reads 2% higher humidity than the others when sitting side by side. Support replaced it without much fuss, so I’m not too bothered.
Questions
The questions our support team answers most about this product.
It is factory-calibrated and not user-adjustable. The included card walks you through an ice-point check: 32°F in an ice bath should read 32.0 ±0.5°F.
Yes. Press the button once for the 24-hour minimum and maximum, twice to clear.
Below 30% RH you get static and dry air; above 60% you risk condensation and mould. The comfort icon flags both ends.
