Where you'd use it
Condensation and damp early warning
Place in a bathroom or bedroom prone to condensation so a humidity spike triggers an alert or an extractor fan automation before mould gets a chance to start.
Loft or wardrobe damp check
Monitor a loft space or built-in wardrobe where rising damp isn't obvious day to day, catching problems over WiFi before they're visible.
Long-life monitoring for spare rooms
Use in a spare room or holiday let where a battery lasting up to 18 months is more practical than a mains-powered sensor that needs wiring in.
