That’s something we can address in my opinion. It’s not rocket science, we know everything about the physics involved in heating a building. We should embed that knowledge in our heat pump controllers.
But do we know the effect of strong wind?
My critical room (living room) is very exposed (3 outside walls and half the ceiling flat roof) and simple weather compensation - based simply on external temperature - just doesn’t cope when it’s windy on the exposed sides. (I estimate the OHTC is 10-15% higher than the zero wind case.) So I need 1-2degC extra on LWT to compensate.
Having said that, I’ve also found that simply drawing the blinds and (heavy) curtains reduces heat loss by a similar amount, and I don’t suppose that anybody is about to programme that into their algorithms…

Yes we do. But the effect is highly non-linear so it’s difficult to predict the heat loss resulting from wind. Small neural networks may help in this regard, I am still investigating the feasibility of that approach.
No definitely not. However at each new time interval the heatpump will see the difference between its predictions and reality, and correct for it similar to how a PID controller would work.

Remember many of these proprietary room controllers are optional, and without them the choose is pure weather compensation or fixed flow temperature.
But we also know there is zero incentives for heatpump makers to improve the control software for existing customers. And there is little incentive for them to care aboug performance outside of the standardised energy rating tests.
There are definitely incentives to do so, because you can advertise with that feature. I don’t know how other HP manufacturers handle this but Intergas provides updates via FOTA, so as long as it’s connected to wifi you’ll get all the latest updates.
