How Low does the Temperature Drop During the Night?

One of my grandsons is staying with me at the moment and he has a raspberry pi.

He is in the process of designing a smart home system.

I started off with a Raspberry Pi for my home automation system - Installed Home Assistant on it. A very capable package with support of loads of different sensors. Setting it up is a bit of a steep learning curve. One thing I did find out very quickly - SD cards will die fairly quickly if you are logging a lot of data. I was having to replace mine every couple of months (did that under warranty).

Current setup is a NanoPi running HA and a fanless/headless box for data storage - It is soon to be changed for a combined HA host & data storage unit (just waiting for some esp32 modules to turn up).

So how low does your house temperature drop during the night?

At the moment, with <5°C overnight temperatures, we're dropping from 20°C when the heating goes off at 2130 to 16-17°C prior to the heating coming back on again at 0700: (black line is the thermostat's measured temperature)



We went away a few weeks back, during another cold spell, and had the heating off throughout and noticed that it didn't drop as far as 15°C despite no heating for many days - the curve just flattened out, rose a bit during the day, and then settled back down again so there's a certain equilibrium to be found as the heat loss decreases.

Last night outside temp 0, heating went off at 9.45 pm (21.5) bedroom.

8.15 am heating back on, this morning room temp (17.0) bedroom.

Lowest I've noticed in any of the main rooms is 15C.

However, we have a small ensuite (on 2nd bedroom) which used to be a toilet inside the garage. It was so cold in there when we moved in in Feb this year, we stored wine & beer in it as it saved fridge space. Last night I registered 8.4C in there, while the rest of the house (bungalow) was around 19C

The previous owners had installed a wall mounted fan heater (useless) and obviously didn't bother with proper insulation. Fortunately, we've installed a glass radiator/towel rail which I'll set to 8C overnight to avoid any frozen pipe disasters.

One of my spare bedrooms (never heated) dropped to 7C last night

Kitchen was 5c when I woke up this am. Window was left on latch though. lounge was 11c. We are having problems trying to get rooms up to a decent temperature with our new boiler. It does not help that we are in a small bungalow( built into a hill side that is open to the elements) that has many air vents under the floors. 

When we have high winds it is freezing in here hence we are desperately trying to find somewhere warmer to live.

My top floor, studio flat never drops below 17°C at night, no matter what the temperature is outside. Great for my gas bill but, as a teuchter, I prefer to sleep in a cold room.

What is it like during the summer? Does it drop to 17°C at night, or remains at 37°C

Drops around 1.5 to 2 degrees at present (with outside temps around 1 to 3 degrees at coldest ). Late 80s property on south coast double glazed with good loft insulation and cavity wall insulation (really noticed the difference when that was done a few years ago).  Last nights Hive graph below

Saturday morning temp in reception room dropped to 17C. Was 20C in the evening. With UFH, heating switches on at 2.30am, to get rooms to programmed temp for morning.

Detached house with 3 levels.

Ground Floor goes down to 14C, when not heated. Reception is on middle level.
