Frequently asked questions
Does a hygrometer detect mould?
No. It shows humidity conditions; it cannot diagnose mould or its cause.
Do I need a smart humidity meter?
For occasional room checks, a basic display often suffices. App-connected meters are useful if you need trends and alerts.

Humidity readings are a clue—not a diagnosis
Take readings in representative places away from radiators, direct sunlight or showers. Check patterns over time. Persistent damp, leaks or mould require investigation of the cause; a hygrometer alone cannot establish it.
