Here is the code. I tried to clean it up a bit this morning and make sure it was all working as expected. I haven't used it fully myself except for testing on my dev hub. That said i do believe the idea is fully functinoal. I will also put this under my github as well..
Here is the code

The parent app is pretty typical for this type of thing. It just calls out that it is a parent and then what it's child name space and such is to call when it goes to set it up. You an put multiple entries in there if you had different kinds of child apps.
The child app is just as the inputs i mentioned above. Then it just has a simple bit of logic that based on how you setup your set point. it will turn on/off the heater device based on either a set temp value or based on a external Thermostat.
The logic is pretty simple: On any temp change for your triggering temp sensnr it collects and calculates your temp on/off values based on your set point source and the variance values. Then If it is below the set point value - variance and the device is turned off, it turns on the heater. If it is above the setpoint+variance value and the heater is on, it turns off the heater. If neither of those conditions are correct it just ignores the change and doesn't do anything.
For dynamic set points by room you will want to use the set point source as a thermostat. This means you will need to setup a virtual thermostat for the room before hand. To make it dynamic you will want to use the built in Thermostat Scheduler app. You may need to adjust this by season yourself though or create multiple instances that you disable enable by season.
