These sensors are designed for stand-alone mode and produce for 3 to 5 seconds about 50 RF messages. This will disturb the RF signals of other sensors. If you send a command to an RFXCOM transmitter it will wait until the AC sensor has stopped transmitting. The reason for this is that it has no use for the RFXCOM transmitter to start transmitting if another sensor is active because both signals are disturbed due to the RF collision.

For door/window sensors the X10 DS90 can be used. This sensor can be used to trigger lighting commands and can also be used for security.
The preferred motion sensor for lighting control is the X10 MS13.
The X10 MS90 motion sensor can be used for security purpose only.
