Remember the times when people told the *current* outdoors temperature by actually looking at a thermometer rather than random weather *forecast* from their smartphone?
As a compromise, I'd settle for people reading the current temperature from the heating controller (it's got outdoors sensor).
@mgorny what about people that get local temperature by decoding aprs packets from nearest airport's weather station?..
@nm0i, above my paygrade, I'm afraid. Also, I don't have airports close by (and thank entropy for that).
