TERMOSTAT program structure for ESP8266 in C++ with multiple sensors

Is this to be an AVR (as in the title) or an ESP8266 (as in the post)?

The ESP8266 is a bit hard to write in C++ without Arduino Core. There are quite a few examples on the web for operating thermostats via ESP8266, but using Arduino Core. For example:
https://randomnerdtutorials.com/esp32-multiple-ds18b20-temperature-sensors/
https://www.instructables.com/ESP8266-and-Multiple-Temperature-Sensors-DS18b20-W/

I'll write how I do it myself, but that doesn't mean it's the only or best way .

Each sensor has a representation in the form of an object that only has knowledge of what to measure and how often. It is the controller object that decides when the sensor object (sensor) will be queried for measured values - based on this, it is the controller that makes the decision, which it communicates to the actuator object, which represents, for example, a relay. In other words, the knowledge of the reading schedule is contained in the controller object. Whether such a schedule is made in the form of an array or a structure is a secondary matter - what is important is that it is easily adjustable from the user's point of view. I would probably first define a structure defining the time intervals in conjunction with the temperatures in those intervals, and then an array of days of the week, the elements of which would be those structures. There would be one such array for each sensor, which could also in turn be an array element of length equal to the number of sensors.

When I write "array" I don't just mean specifically static [] arrays, but could also be dynamic containers e.g. std::vector, std::list, std::map etc. - it all depends on whether there will be a rigidly predetermined number of intervals or number of sensors.

In C++ struct or class are practically the same thing, so structures too can contain functions that will be responsible for reading/writing a given structure along with error detection/correction.

Old and unfinished project: https://github.com/teuthid/eq
Applies to AVR, but the sensor polling and actuator control mechanism I wrote about above is implemented.
