Climate

Keep every room just right. Temperature and humidity sensors, air quality monitors that spot a stuffy room before you do, and a smart radiator valve so you only heat the rooms you're actually using.

Before you buy

Heat room by room. Pair a room sensor with a radiator valve so each room heats only when it needs to.
CO2 over 1,000 ppm? Time to open a window. A CO2 monitor spots a stuffy room before you start to feel it.
Watch for damp. Humidity that stays above 60% in bathrooms and bedrooms invites mould, so air them early.
