Looks interesting 
I use 🔥 Advanced Heating Control with schedulers for heating plans.
Schedulers have an attribute with time of next event.
In my case i think its important to also use the flow temperature for calculation. I dont switch heating off at night, i set it to eco temp. So you dont know if all water is cold or already heated up - which takes longer with more TRVs open of course.
I need it in the evening too to heat kitchen/TV room (the coldest room in house),
