I can't say that I am 70% satisfied. A look at the device's logs shows that when there is no presence of a person at all, things are better and it shows greater consistency. However, when there is the presence of a relatively still or sleeping person, things get confused and it shows Presence of a person-Absence-Presence, etc., every few seconds or a few minutes. Check the logs of different rooms. I don't know if it's due to the placement that has been done at 2.5 meters (outside specifications and instructions) because lower, e.g., at 1.8 - 2.0 m, would look bad and raise questions about whether it is a spy camera! Anyway, it is a cheap sensor, we can't expect much, and if combined to work with another in the same room or in other rooms or, for example, together with door sensors or locks and other such devices, routines or scenes can be created that will require the cooperation of 2-3 parameters to do something, e.g., to turn on a light or trigger an alarm, etc., and this can save you from false activations. That's how I work it, and something happens! Also, I have set the maximum sensitivity. In conclusion, the positive is that when you are there, it activates, especially when you move, but the negative is that it may not activate when you are there in inactivity, e.g., watching TV or sleeping, and show that you are absent. They are very good at "there is no presence" - as long as you are indeed not there, but they are not when you are there, and sometimes it shows you as present and sometimes as absent.
