Presence sensor that actually works?
Discussion
I'm trying to automate the lighting in the kitchen/diner, using Home Assistant.
I've already got the lights in the hallways and bathroom automated, using Tapo motion sensors. These work great in areas that you pass through, but are rubbish if you stand or sit relatively still. The detection times out, and it rakes exaggerated movements to trigger again.
I bought an Aquara FP2 0resence sensor, and spent several hours setting up the room boundaries, furniture, exit points, etc.
It copes quite well with just one person in the room, during daylight.
With 2 people, it starts seeing "ghosts", detecting extra "people". The "off" state doesn't trigger, as it thinks there's still someone in an empty room after the real people exit.
Gets worse at night, possibly more reflections from windows when it's dark outside? Can easily see 5 or 6 people when there are only 2.
Does anyone make a sensor that actually works in a fairly reflective environment?

If 100% reliable presence sensors aren't "a thing", would it be possible to do using motion sensors at the entry point?
Maybe 2 sensors, so HA can tell the difference between entering and exiting, based on which sensor gets triggered first?
The entry point to the kitchen/diner is effectively a short corridor, could have 2 sensors scanning across the corridor.
I've found the Tapo motion sensors to be 100% for triggering motion when walking past, but completely useless at detecting the small chages when seated or standing relatively still.

Try the everything presence sensors they are basically the best you can get
Reading some reviews, comparing this one to the Aquara sensors, it seems to suffer the same problems with "ghosts". It adds a normal motion sensor, but can't do "zones".It's really quite annoying, as the Aquara works perfectly in detecting when someone enters the room, but seems to lose track if they become stationary for more than a few seconds, and registers them as a new person when they move again. Now there are 2 or more "people" in the room, so when the real person is detected correctly leaving, there's still a "ghost" presence in the room. "Off" automations fail.
I tried it again this afternoon, two people going in and out of the kitchen, often nobody actually n the room for multiple minutes.
At one point, there were 5 people shown as being in the room.
At no point during a four hour test period was the room shown as empty.
Come into the room, switch on the kettle or coffee machine, leave a "ghost" standing there. Sit down at the table with your cuppa, leave a "ghost" sitting there when you get up again.
This is despite mapping the room edges, adding the furniture, marking the exit points, running the AI learning multiple times, etc.
