I use it via Tuya to control my dehumidifier, and it has helped me a lot. The sensor is outside the device, so I can place it wherever I want to measure the humidity. This gives me better control over the room’s actual humidity. After calibration, its readings are roughly within one unit of the other thermo-hygrometers I have.

With two automations in Tuya, I set separate humidity levels at which the compatible dehumidifier turns on and off. For example, it can start at 63% and stop at 58%. This is especially useful when the dehumidifier’s automatic mode doesn’t maintain the desired humidity properly, or when you want greater accuracy. I enable the automations whenever I need them and control it manually the rest of the time.
You can’t imagine how much electricity you save this way, since the dehumidifier’s sensor is overwhelmed by the humidity because it is located inside the device and always shows a higher humidity level than the surrounding environment. The same applies in reverse. In a 30-square-meter living room, the dehumidifier may show 55% at one end, while at the other end it may be above 60%.
