Wyze Motion help?

I have about three Wyze  Motion sensors that I would like to use for smart home automation. For example whenever the front door opens if there's no motion on any of the motion detectors it turns on a couple of lights as in that would be somebody walking in the door and no one else is home, or when I'm in bed and I get out of bed in the middle of the night my bedroom lights turned on real dim for a sort of nightlight then they turn off when it doesn't detect motion. 

I've placed them about six or 7 feet high, more closer to seven maybe 7 1/2, and they do work but they don't seem to work reliably. For example I have one in the kitchen and when I walk in the kitchen I want the lights under the cabinet to turn on. It Unless I sit there and keep moving intentionally in front of it. Same thing with the living room when I walk to the door when I'm inside and open the door the lights will turn on because The living room motion detector detected no motion but I just walked in front of it, and said I have to intentionally wave directly in front of it. And I've tried messing with the sensitivity settings that doesn't seem to do anything. 

Am I the only one or is this happening with everybody? If these could work reliably that would be amazing. And yes I'm talking about in the Wyze app When I'm looking directly at the sensor updates
