Sonoff Motion Sensor Review: PIR or radar sensor, which once is better

This video compares the new Sonoff radar presence sensor and the older PIR motion sensor. As it turns out one is better at sensing human presence and the other is sensing motion. But let's see how they perform in particular indoor scenarios.

I just wanted to compliment you on your great video! You showed me exactly what I wanted to see, and I had watched at least 10 videos before this one that did not show any testing at all! Definitely subscribing :)

Excellent report with lots of serious scenarios: great job !

Super nice and deep review.
1 - @02:16 - yes and that is the reason why you create a helper in HA, a timer. Set it for i.e. 5min. PIR starts timer, when time starts, light turns ON. After 30s PIR will go off but you still have light ON due to timer. There is no way you will not move during 5min. Next time PIR detects movement it restarts the timer and again you have 5min. That is how I do with all my PIRs.
2 - Also I realized that Zigbee PIR sensors are much slower than ESPnow PIR sensors.
3 - each PIR sensor that is battery operated goes to UNCONDITIONAL sleep after reporting motion. This is how these sensors save the power. No motion within this time wakes up the sensor. Otherwise they would die few days on these small batteries. Some sensors have this time adjustable, some not.

Thank you for the review!
Ideas for testing.
1) While being on WC, if the sensor reacts on somebody's presence behind the door or wall.
2) If it is able to detect motion through a wall if it is intended (e.g. if I place a sensor in WC direction to the bathroom and want to react to somebody's presence in the bathroom).
3) If placed on balcony, if ONLY reacts on human presence, e.g. does not react on wet cloths, that might be placed there.
Thanks!

I believe the presence sensor maxes out at 4-5 meters or something like that on high sensitivity and less in medium sensitivity? So one probably needs to keep that in mind when placing those.

Hi Varga! The only issue with my sensors Sonoff SNZB-03 is that if I work in front of them for 6 - 8 minutes sometimes PIR does not detect me even I am moving. Sensor getting stuck in a detected state or not re-triggering an automation within the refractory period. Did you try to walk in coridor for 8 minutes to see if SNZB-06P detect you every time?

Is the light sensor usable within ewelink app? Do the default dim and bright light triggers in scenes make it practical for every day application?

Hi, could you please tell me what is the detection angle of the sonoff presence sensor ?

[TR]

Hi All,
Can this presence sensor be used without a power supply and if so, how long do they last ?

[user]

I wonder how it will work out a garage?

[theattorney]

It appears the sonoff exposes two sensors to zha, a motion sensor and a presence sensor.

I have bought 2 devices and I have placed them in the bathroom, my intention is to turn lights and sockets on and off but I have problems, I have placed them in different areas with different sensitivities and in all cases I have had false positives. Why can this happen to me?
