What is this activity within the X10 usage chart?

[Kaptan]

I have a very simple setup with a Protector+ Security Console + CM15 with AHP.
In the below screen shot you can see all of the modules I have with their addresses.
I am quite confused by some of the orange and red markers on the graph.
Why are the following an issue?
A3 & A4
B1-B3
All of J & O
P16
I have never set anything on J or O, yet in my activity monitor I see a Receive RF - O TV
Any idea what this means?

Thanks for any advice.

From what I have seen, the orange markers as when an address is called from within AHP/CM15A but does not have an associated device defined (E.G. called from a macro). The red markers are from an external source (E.G. your red A6 is from the dusk/dawn sensor of your A5 motion sensor).

And of course, a green marker indicates there is a defined AHP module set to that address.

Use the "Clear History" to get rid of of the orange & red makers to see what ones come back.

Thanks for the tip, I didn't realise this graph represented on-going traffic, (rather than just assigned addresses).

Once cleared, all that remains for now is the green defined modules. After a few days I'll see what comes back.
I'm still confused as to why the HC J & O have shown up, but I'll keep my eye on the activity monitor for this.
And the one-off P16, now that's just weird.

The P16 maybe normal. I have seen it mentioned before. Feeble memory eludes me on what it was. Hope someone remembers.

P16 will be there everytime the computer is shut down and restarted.  (I don't know the real purpose.)  You can even assign a ghost module there; create a macro with P16 as the trigger, and it will activate on start-up.
As for the other red squares, add a ghost module at J1 and O1 and see if that doesn't eliminate the yellow ones.................

I had a look at the history this morning and you are spot on JMac.
Now to think of a creative macro to utilise this P16 command.
Turn on speakers?  Turn on Printer?  Turn on external drives? . . . the choices!

Oh, by the way, none of the J or O addresses have reappeared on the chart, so I don't know what that was about.
