My “plant room” is the airing cupboard at the top of the stairs, and is considerably hotter than anywhere else in the house. So, I don’t use the RoomTemperatureZone1 reading as it’s not representative. [There’s also no room left in the cupboard for airing any washing, but that’s not important]

Instead I have 5 wireless thermometers that are continuously read by an old Pi under the stairs. This gives me a reasonably good average for the whole house. One of the bedrooms is south-facing, occupied all day, and has several heat sources, so is much warmer than the rest of the house, but is countered by a couple rooms on the north end that are naturally cooler than the others [I don’t do micro-zoning].

When there’s no solar gain going on, and the heat pump is the primary source, then the room temperatures are typically within 1 degree of the average (black line). The lounge (orange line) is usually close to the average; the room stat that controls the heating is also in the lounge.

I use this average temperature to “turn off” the heat pump when the house is deemed warm enough, overriding the room stat. (I’ve [documented the issues with my room stat](https://community.openenergymonitor.org/t/anyone-monitoring-a-new-r32-ecodan/19577/15) elsewhere)

Family members opening windows and doors as soon as the sun comes out is a challenge for any heating system. I find myself turning it off manually at the room stat, and then having to leap out of bed early the next morning when I remember I’ve not turned it back again.

It does seem daft to be heating the house in the morning on days which are going to become warm out anyway. I do have forecast temperatures in my system, so I _could_ try predicting it, but not sure it’s worthwhile. Since I’ve [just] gotten onto RHI, which will more than cover running costs, I try not to worry about it so much.
