• When you refer to a Monitored Housecode, think about a Monitored Alarm System. Someone (something) is keeping track of (i.e. REMEMBERING) it's current Status - TRIPPED/UNTRIPPED, ON/OFF.
  
  
• When you need to know the current Status (ON/OFF) of a REAL or DUMMY Module *AFTER* it's been set, you need to use a Monitored Housecode.
  
  

  
  IF A1 is ON AND it is 5:00PM
  Then turn ON C1

  
  Say A1 previously got turned on at 4:45 PM. For the macro to work, the A HouseCode must be Monitored for AHP to that realize A1 was (still) ON when it became 5:00 PM.
  
  
• If the Module Address is merely being used as a MACRO TRIGGER, there is no need for it to be Monitored.

• When you refer to a Transceived Housecode, think about the origin of the word - Transmitter / Receiver. A Transceived Housecode is one that is RECEIVED (via RF) and then IMMEDIATELY TRANSMITTED (via PLC) (i.e. it's RELAYED).
  
  
• If you currently have (one or more) Transceivers installed and you are KEEPING them, you DON'T want to Transceive that HouseCode in AHP.
  
  
• If you currently have (one or more) Transceivers installed and you are REPLACING them with the CM15A, you DO want to Transceive that HouseCode in AHP.

• Signal Suckers - like a sponge or a female mosquito, they 'grab' all the available X10 signal and leave none, or very little, for your modules to 'hear'.
  Example: Power Strips
  
  
• Noise Generators - like not being able to hear the phone or the door bell when the vacuum cleaner is running, they 'pollute' the power lines with noise making it very difficult for your modules to 'hear' actual X10 signals.
  Example: Power Supplies
  
  
• Filters are 'Open Circuits' to X10 signals -
  
  
• Signal Suckers cannot SUCK the X10 signal away
• Noise Generators cannot OVERPOWER the X10 signal
