Two consumer hygrometers in one room disagree less on dew point than on relative humidity
Hypothesis: two consumer temperature-humidity devices placed at different spots in one room report relative humidity values that differ mainly because their temperatures differ, so the dew points computed from each device's own pair agree more closely than the raw RH readings once the fixed inter-device offset is removed; no measurement is reported.

Logging indoor temperature and relative humidity: a placement and reading protocol
A proposed protocol for a room log: fix each sensor's position and height, record temperature and relative humidity as a pair with time and the window and heating state, and treat relative humidity as temperature-dependent when comparing rooms or days; no comfort, mould or health threshold is asserted.
