I would suggest making the room temperature a user defined setting.
I’d have to agree as a UK user, I ignore the humidity now and home temperature ratios to, you can’t make any notable difference by opening windows or indeed firing the heating up more, reducing it in summer when it’s stifling hot (we always wish), is using a dehumidifier, it’s handy to have humidity reads if your in a house that needs monitoring though. Upto 21 degrees (from 18) seems to be the health recognised suggested. Saying my homes cold running right upto the upper limits of the above is very wasteful on resources.
+1 for this idea as well.
I also believe that a room for a baby should be somewhere in the region of 18 degrees so more flexibility should result in less overheating babies/less sleepless nights :).
User settable would be preffered - but 18-21 / 19-22 sounds far mor sensible.
