Just received a V572RF32.
I interfaced it to my XTB-IIR and noticed in my AHP activity monitor a loop of G8 on/off.
Oddly, this isn't showing as an RF signal put PLC. I watched the V572 and XTB LEDs and the V572s LED flashes first as though it is receiving RF, then the XTBs showing it is being passed onto the power line.
I tried plugging the V572 into the PSC05 instead of the XTB and got the same thing.
I removed the V572 and the G8 cycle stops.
I'm not using G8 for anything but would still like to figure out why this is happening.
Has anyone else ever noticed this from a V572?

I haven't noticed anything like that but it could be something close to you that is triggering it.  I believe you can download the software to interface with the v572 and tell it not to use the "g" code.

[J.B.]

I've configured it not to use certain HCs.
I am using HC G for several modules but not G8.
It doesn't appear to be RF.
AHP activity monitor is showing "receive", not "receive RF".
When the V572 is removed from the system this stops so that is why I'm assuming it's the V572.
The G8 on and off signals seem to be looping every 30 seconds to 1 minute.

It doesn't appear to be rf because the cm15 doesn't have the range to pick it up as rf, hence the need for the v572.  The v572 is seeing the rf and then putting it on the powerline, then the cm15 can see it as a power line signal.

Also go into hardware config , transceive codes in AHP and tell AHP not to transceive any codes and try that.

Also if you EVER had a g8 module setup in AHP it might not have deleted it all the way.  Make sure your recycle bin in AHP is empty, clear the cm15 and redownload to cm15.

Make sure you don't have a motion sensor set to g7 as it will use g8 as its dusk sensor.  Hope this helps.

[J.B.]

No motion sensors setup and I normally try to use the ActiveEyes that allow you to disable the +1 code. If I do use the other sensors, I tend to keep them to one HC and leave a blank +1 code if not using it. (Eg: A1+1=A2 I leave A2 unused)
The CM15A is set to transceive none and I have just moved to this location and setup AHP from scratch, so G8 has never been used.
AFAIK, I've never used G8 in my setups at all.
I've done an antenna mod on the CM15A and it's range isn't bad, but I picked the V572 up anyway where it had such good reviews.
Seems this is only happening if the antenna is connected to the V572. It may be picking something up in the distance but with the neighbors a good several hundred feet away, I figured it couldn't be the case.

I have had this problem, but not with G8 just another HU Code.  It has happened just two times in several years.  There may be an update to the units' firmware, but since it was such a rare occurrence I never folowed up on it.  If you are able to verify that (the update) please let us all know.

[J.B.]

Thanks for the replies.
I'm going to call it a stray signal that is being picked up for now.
I thought swapping the coax that came with the unit had fixed this but I spoke too soon.
I know my neighbors here and none of them are using x10.
I am also 100% certain I have nothing set to G8.
If this is picking up a stray signal, it has to be coming from 600'+ away. I would say that the v572 has "fairly" decent range if that is the case! 

[JeffVolp]

The CM15A does contain its own RF transmitter.  Just as another test, try unplugging the CM15A to see if that stops the stray transmissions (as seen by the LEDs stop flashing).

It's got to be a stray signal. I doubt noise would produce constant G8 on and off signals.
I did unplug the CM15A and still had activity on the V572 and XTB.
It does seem to have slowed down now and not seeing G8 as frequently.


On another note, this combination of the XTB-IIR and the V572 is so much more reliable.
Even only having the setup for such a short time, it is very easy to see how many benefits I have compared to my prior setup already.
I went out through the yard with a palmpad and sent sequences of commands that I checked in the activity monitor and it is reliable to at least 300' behind a large out building.
I think I can live with one HC/UC showing up that I'm not even using. I just hate not knowing where it's coming from and weather more will start popping up over time.

Thanks for the troubleshooting suggestions. 

[J.B.]

Well, I figured I'd post an update on my G8 oddity.
Turns out it is my floodcam.
I had it set to G16 and for some reason when the lights trip on it I am getting G8.
When motion stops, about a minute later, it turns them off.
I didn't even notice this because I had turned the bulbs out slightly as they were coming on too often where I have the camera positioned.

Now I find it odd it is sending G8 though. It is set to G16 and I would think when it trips on, it would send an off to other cameras that may be in a sequential group of 4.

[pconroy]

That makes me wonder -- if the Motion Sensors Dusk/Dawn are "+1" UnitCodes - what do you get when you set the device to P16, for example?

[Brian H]

I believe it loops back to unit 1.
So P16 Motion gets you P1 dusk dawn.
Some have tried to defeat the dusk dawn with unit 16 only to have dusk dawn show up on unit code 1.

[J.B.]

I spun the dials around several times and eventually it seems to have started working on the set code again.
I thought the Floodcams only sent RF like a normal wireless cam to turn off the rest of their group of 4.
Didn't think they had a +1 at dusk feature like the Eagle and Active Eyes.

[Brian H]

OH spinning the dials corrected the problem.
We have seen modules change address when the switches get dirty and make bad contact. Spinning the dials sometimes clears the film of crud from the pc board runs used for the dial switches.

The camera are switched on and off by power line signals not RF signals. The camera remotes send an RF command to a transceiver that sends the power line signal to the addressable power supplies of the cameras. I don't think the Floodcams have a 310 MHz RF transmitter in them to send on and off signals to other cameras.

[J.B.]

That is what I had thought, also.
I was reading the Floodcam manual and saw this:

"These dials set the code for
turning the camera and
floodlights on and off from
X10 remote controls. Also,
when the camera turns on
with motion it transmits
wireless Radio Frequency
(RF) commands to turn off
other cameras in its group of
4 (requires a Transceiver,
sold separately)."

This makes sense as the floodcams do not come with an addressable power supply (intended to be hardwired) as the standard x10 cameras.
If using multiple floodcams, I assume this is how they address power in their groups, though I've never seen AHP pickup any RF when the camera powers on or off.
I see no reason why they wouldn't send PLCs to others cameras.
