BT Near frustration

[coyote1]

I'm trying to utilize Tasker to do the following: when any paired Bluetooth comes within range of the Android tablet running Tasker, then Tasker starts a task. The tablet is always on, with the screen always lit.

I don't want to have to manually do anything. A paired phone in my pocket, for instance, should be detected by the tablet as I approach it and the task should be triggered. Yet it's not happening!

Am I misunderstanding how this utility is supposed to work? Or are there settings (& perhaps other plugins) that will make this work as desired?

Btw, the task is to have Smartthings automatically turn on the porch light. It works if I turn bluetooth off on my phone, and then turn it back on a couple minutes later. And I can trigger that in Tasker via Bluetoith AutoConnect by turning on the display, and it catches the light from outside occasionally. I wa hoping for better....

Just a bit more detail: the ultimate goal is to have the light go on, and the (schlage connect) lock auto-open, when my wife arrives. She goes for a walk with her 4th generation iPod touch, and I'd like the door to unlock as she walks up the walkway without her having to enter a code. She comes back from shopping in her bluetooth connected car, and I'd like the front door to auto-unlock so she doesn't have to fiddle with the lock while carrying bags of groceries. Both the car and the ipod have been paired to an android tablet.

My thought is that this tablet, sitting near the front door, should be able to 'ping' the bluetooth world for its paired devices every few seconds and, when it sees one has arrived nearby, take an action.
(Secondarily I'd also like it if when the tablet no longer sees one of those paired devices nearby, it takes another action.)

But it's not working out that way.
