Thanks for the link, but I'm already using 1-wire temp sensors, so I
need something which can accommodate one of those.  They do look neat
though.

Yeah, I've found that! :-)  Trouble is that it's far neater to be able
to mount them either on the ceiling, or near the floor.  What I've done
in rooms where it matters, is mount them in pairs, one at ceiling level
and one at floor level, and then take the average.  That seams to give a
reasonably accurate reading.  In some rooms I've even quaded them, and
taken the average of the four.  The beauty of 1-wire is that it's so
cheap/easy, it's not a problem doing that.

...Not that it really matters too much in my case.  It's purely for
interest that I take temperature readings, I haven't got around to
HA'ing the heating system yet (that's a job for next winter... Maybe!).
