I bought a 5 pack of xiaomi temp sensors from Ali express... They were like $5 each? They're Bluetooth but you can bridge to HA using an esp32 with esphome. Really cheap way to get some resolution on how and where and when the house is heating/cooling.
I was surprised at how poorly I understood how to manage the temp of my home. Knowing really is half the battle.
