This is what i am tryng to do:

I have a customer that has a sports court. He wants me to create a button on an RK- that turns on/off the lights at the sports court. What i did was i found a 12v coil contactor and attached it to one of the relay outputs on the XP8. Press the button on the RK3 and the lights turn on/off.

Now the customer wants to have a push button or switch outside to also control the lights. My thought was to have a doorbell button powered by a 12v power supply and have the output of the button go into a sense input on the XP8. I am sure that will work. But from here i am lost. I do not understand how the RK3 will know if the lights are on or off from the button. Figured out that i will need to use some flags but not sure how to program it. Anyone have any suggestions?

You could try sensing voltage and use that to indicate status. And put in an RK1-2 instead of the door bell.

I mean use the status test command if it is on do one thing if it is off do another
The door bell is momentary and might be hard to use. RK1 would be better and get 12v from you output for status /sense in
Never triied it but it should work.

you could set a flag on the xp8 itself when you turn the lights on via the 12v coil, test the flag to to determine if you want to turn lights on or off in a single macro. Your sense event from the doorbell switch would also initiate this macro so it will always toggle regardless of which keypad triggers it because the logic is in the xp8.

macro:
test flag "x"
if set then:
open relay
clear flag "x"
if not set then:
close relay
set flag "x"

If you need to know on the rk itself what the status of the lights is then test the flag on the xp8 from the rk via macro or have the xp8 flag trigger a button status(reversed, invisible, etc) to let you know.
Hey, thats a nice plasma, you can put that in the back of my truck...

Set your sense to closure sense, and do not use a lighted button.

How about feeding the 12v THROUGH the relay and parallel the 12v into one of the voltage sense inputs?  Run the Ground to the 12v power supply ground and the + to the relay output.

Then you wouldn't have to rely on flags; you would be testing if the actual 12v was present.

That will work, but does it apply to your situation?  I'm a little brain dead.
