Short of manually disconnecting the CM15a antenna, how does one avoid intermittent conflicts?
Boiler: We all know how bad the reception of the CM15A is; that is until you do not want it to receive any signals.
Another member,
Marineau, tried a few methods here:
Disable RF signal receiving on CM15AThe only way to 100% prevent the CM15A from receiving RF is to kill the front-end of the receiver.
I believe that all security RF signals received by the CM15A are sent to AHP where the software converts it into a standard X10 HC/UC address. And then those addresses are used to trigger what ever security macro you create. This is one of the reasons using security macros have to run from the PC and not the interface. The CM15A can't do anything with the RF other then pass it on to AHP. AHP doesn't know what to do with it unless you have On Alert.
I totally agree with you here.
Pure RF doesn't actually do the triggering for any macro does it? The RF is converted into a usable H/U code first.
The CM15A extracts the HC, UC and command data from the RF to make it usable.
What you are saying is that with all house codes marked as None for transceived that a RF signal will still be converted into a HC/UC and then will trigger a macro? As a test I unplugged my V572AB and used my palmpad to turn on a hall light (A5) "A" being one of my un-transceived house codes and a macro set to A5. Neither one would respond until I plugged the V572AB back in or set "A" to be transceived.
Stopping a HC from being transceived only stops RF signals from being sent out as a PLC signal; it does not stop the CM15A from receiving the RF signal nor does it stop AHP from acting on an RF signal. Disclaimer: at least on my 2 CM15As that are date-coded 06A02 & 06F26.
As I stated in other posts, all my RF remotes are each dedicated to their own UN-Transcieved HC. Those HC's in AHP just have macros to respond to each of the remotes buttons. This has been working for me since day one.
A macro stored in the CM15A will respond to an UN-Transceiver RF signal. A macro stored on the PC will not reliably respond to an RF signal if it is not transceived. I say "not reliably" because I seen it work sometimes and not others, and was unable to pinpoint the reason.
A couple of things about your test:
Is the macro stored in the interface?
I don't know how the CM15A and/or AHP responds to a module that has a macro that turns on that module. Theoretically it should start an endless loop.
Make a macro on another UN-Transceiver house code to turn on your A5 Lamp. Do not associate any modules to the macro, just a single stand-alone macro. Now try an RF remote set to that HC/UC and see if your A5 Lamp comes on.
I do have DS10As that are NOT assigned to the DS7000. They are assigned to my V572RF32.
And that is understandable and fine. My concern is with someone who is not using a DS7000 and only AHP with OnAlert. If they choose to use the V572RF32 as a better receiver and convert all their security devices to a PLC signal, then they have a much less secure set-up.
NOTE: Housecode L is not transceived on the V572RF32. This means if the V572RF32 receives a stray RF L1 On or RF L1 OFF or RF L anything, the V572RF32 will not transmit that onto the powerline. Also since no housecodes are transceived on the CM15A, they are ignored there as well.
So the only way your macro can be triggered is by the storm door DS10A being opened OR if someone physically plugs a hardwire X10 controller into your house wiring somewhere that is set to housecode L and presses "1 on".
But the CM15A may still trigger a macro in AHP. So an unexpected RF signal can still cause unwanted results that a true DS10A OnAlert security macro wouldn't, because it does not respond to PLC signals or standard RF X10 address signals.
So to sum up what I am saying:
1) Using a V572RF32 to convert any security devices RF signal to a standard X10 PLC signal can open the door for possible unwanted results and definitely takes away the security of the original signal.
2) "Do Not Transceive" does not mean "Do Not Receive". This is a bigger concern if someone uses the V572RF32 for better reception of all their security devices and uses just standard X10 addressable macros instead of the secure OnAlert macros.
3) To use the V572RF32 for non-security uses of devices such as a DS10A (like
spam4us said he does) is OK because it's no different than any other X10 RF device (like an ActiveEye motion sensor).
