I have a programmable thermostat at home and being the indulgent human I am I have a rule set that the house starts to warm up at 5am so that when I get out of bed it is warm and not cold 😀
Of course that sounds good in theory but what proof is there that the thermostat actually delivers ;).
I setup a temperature logger to test how effective this actually was and I must admit was pleasantly surprised. Over night temperatures stayed at 21.3°C but as soon as 5am came around temperatures went up to 21.9°C enough that I feel much better getting out of bed in the morning.
