433Mhz On/Off


If using 433MHz to control T1/T2 wall switches, is it possible to use 1 433MHz 'frequency/button' to 'on' the switch, and a different 433MHz 'frequency/button' to 'off the switch?

This way, I can use 433MHz to 'off' the switch without knowing the switch's state.

Instead of using the same 'button/frequency' to on/off the switch.
