All the Lm465's are the new softstart style.
I ended up solving this issue however.
It turned out to be caused by having another transceiver in the same room as the CM15A.
I still don't undertand why exactly it would cause this issue, but powering off the other Transceiver resolved the issue with the All Lights On working but All Units On not working for 1 lamp, so it must NOT be a software bug as I initially thought, but moreso tied into some strangeness that having 2 tranceivers on the same housecode can cause. (Perhaps this is because I started to notice doubling up of commands in the log due to 2 transceivers or something)
Is this something that is not advised to do? (having 2 transceivers in the same house or on the same house code).
Initially when I set things up, I had thought that some of my lamp modules were not on the same phase in the house because x10 signals were not making it to all devices. This turned out to be not true as well but in the meantime I had set up a workaround of having another transceiver in the house. Now, I realize that all the devices in question were on the same phase, but that they were just having x10 signals blocked by a few items:
1. Laptop powerpack
2. A pair of 3M Air Purifiers in 2 different rooms of the house (model number 3M FAP03-RS).
I really need to unplug everything and find other x10 signal killers in the house one of these days as I am certain there are others, but the ones above are the 2 items I have seen completly destroy x10 signals. In fact, the air purifiers do not even need to be on, only plugged in, although, when they are plugged in, a small led light lets you know that the unit is getting power, but even with the fan blade inside the unit not moving, the x10 signals get killed.
So now, the only other quirkiness with AHP that I have seen is that my purchased plugins did not register properly and I have to resolve that issue. There is a thread here with some info that I am looking into, worse case, I just let x10 know that I didn't get my smart macro and other plugins just yet (they never sent a link with the plugins so I had to do the workaround and enter the -1 after my order number to d/l AHP but that didn't alow me to get my plugins that were supposed to be included with my CM15A so I will be getting around to that soon).
But even without the smart macro's, AHP seems like it has a million features and just going through everything that it can do by itself without the smart macros is amazing. I am pretty impressed with the CM15A and AHP so far (except for not being able to use a surge supressor on the CM15A but that's another thing I need to work out).
The biggest drawback to x10 is the fact that so many items in a standard house can kill x10 signals. They really need a way around that. I still haven't decided on which filter to purchase and if I will still be able to have surge protection on some of my items. I would not want to hook my expensive 3m air purifiers up to AC without surge protection though, so currently I have disconnected them until I find a good x10filter\surge protector combo, if one exists and is reasonably priced. I saw a link before for one but it was not by a company I recognized. I keep hoping APC makes one but I am starting to doubt that they do, and all of their products will probably remove x10 signals from the line thinking its just noise and I don't feel like installing an all house protector just yet.
