How have you got your central heating/hot water programmed?

Here's a plot from the Hive app:

The heating is turned off so the boiler runtime is zero. As it was a lovely day I had all the windows open and spent the day outside. If the heating program was still enabled it would have fired up the boiler at certain scheduled times below 19C, in the morning and particularly after 8pm.

It's interesting to see the thermal gain from the sun as it moves around the house and when all the windows are closed keeping the heat in.

In the winter I don't want the house to get too cold overnight. In the summer I don't care how cool it gets overnight as I know it'll warm up as soon as the sun rises.

I have a Bosch smart boiler and smart thermostats in every room. I was randomly awake at 3am a while back and noticed the slight noise of the boiler working. Turns out the room on the downstairs north side of the house was dipping below the 13C at times at night, so the boiler was firing up (and heating the upstairs bathroom, which is the non-regulated radiator in our house).

Heating has been set to away mode for the summer now.

This is basically us as well. We have a minimum temp at all hours. We also found that it could trigger the boiler to fire up on a particularly cold night even now. So we now turn it off, well technically its on but it would need to basically snow now to get the boiler to fire up.
The house warms quickly with solar gain this time of year, so we actually want it to drop as low as possible overnight. Its never realistically going to get that cold, and if by some freak it did, we can manually turn it on for an hour to warm up.

Starting the house at 18 degrees at 7am means it is more likely to get a lot warmer than if its starting at 13 degrees.

Ideally I would want to set the temps by month. So I could for example set 13 for Oct to March and 6 minimum from April to Sept
 
Same as many of you.

The kitchen only gets full sun in the morning as an oak tree blocks the SW light. So it can dip well below turn on threshold on the trv. Particularly at night before the sun comes out.

As others said I don't want/need this to trigger the boiler at any time so the "all off" button is on.

Is just not needed. Technically you should just be able to leave tado etc on all year round. But it just doesn't play out like that
 
Tado app looks loads better than the Hive app. I'm going to install the Hive TRVs to most rads before this winter, meant to be a pain to setup but determined not to heat empty rooms this winter
