if you just want to add ds18b20 and IR transmitters in every room, the easiest way is put "AG Pro"  or KC868-AG to every room, it use by wifi, easy to place anywhere, IR and RF inside, it can use home assistant and Tuya app for IR&RF at the same time. ESP32 also include temperature sensor. if you want use DS18B20, in the box have extend free GPIO, you can solder DS18B20 on PCB, then the "AG Pro" can send IR&RF signal and monitor temperature.
