Has anyone reported (or found) the bug regarding power being given to a pressure plate, or trip wire, from a sensor even when that sensor is not detecting?
I can create a little movie demonstrating the issue, but if it's been covered then I won't bother.
Just to confirm this is an issue relating to sensors and being connected to either pressure plates or trip wires. Those two items will trigger even if the sensor is not seeing you. It acts like a normal relay pass through, ignoring the state of the sensor. This is only for plates and trip wires, if you connect a sensor to an electric fence then it works as expected (if the sensor see you, power goes to the fence post(s), and it doesn't if it can't see you).
---------------------------------------
To replicate:
- Get a sensor and set it up so it feeds two things; a set of two electric fence posts, and a power plate.
- Connect the power plate to something that triggers when powered, a dart trap is ideal in this instance.
- Turn on the power and stand so the sensor detects you.
What you will find is that when out of sensor view (ie: sensor not triggered) the electric fence will not be active, you can walk through it with no effect. However, the pressure plate (and the trip wire) will automatically fire, even though the sensor is not seeing you and should not be providing electricity. If you take your wire tool and look at both the pressure plate and the first of your electric fences you'll see the fences are not active when the sensor is not active, yet the plate
is active despite the sensor not seeing you. If the sensor sees you, then it works as you would expect, the electric fence is active and the pressure plate is active. Go out of range of the sensor and it reverts back to the (incorrect) situation where the sensor is not active and neither is the electric fence, yet the pressure plate is active. You don't need to stand on the pressure plate when it has power in this instance either, it is like a pass through.
Current fix:
There is a solution to this, and that is to introduce a relay before the pressure plate, so.
power =>= [sensor] > [plate] > [dart trap]
-- the dart trap will trigger whether the sensor sees you or not, it acts like a pass through ignoring the sensor.
power =>= [sensor] >[relay] > [plate] > [dart trap]
-- the dart trap will operate as expected but only when the sensor sees you and you are standing on the plate, otherwise it won't fire.

As I said, I could create a vid (I have a test setup on a creative build just to double check the bug was happening) if that would help.
