I added a couple of new devices today, and as I was browsing around my links in the Insteon
explorer, I noticed some links not found. No problem, I've seen that happen before. I just
rebuild the links and I'm usually good to go. Well, while it was rebuilding the links, I
noticed some red eventraw=05 log messages roll by. I am assuming that something is not
good. But how do I know which device is causing the problem? That message rolled by for
just about every link as it was created.

Update: All the links that I was rebuilding have been recreated and everything
seems to be working fine. I don't see anything wrong, other than those eventraw=05
messages that scrolled by while rebuilding the links. I don't know if it is
something to worry about or not.

The Event 05 is a NAK. The previous command did not receive the expected ACK. If this is a frequent occurrence it indicates a powerline reliability problem that should be addressed. The 120V legs are not coupled correctly, noise on the powerline, something attenuating the Insteon signals, etc.

Oh, that doesn't sound like fun to troubleshoot. I don't think it's caused me any problems yet.
And it doesn't look like I've had a lot of NAKs. The top device is the one I just installed, so it
has only had about ten uses. Since the graph shows percentages, just one or two NAKs will look a
lot worse. Of course, the way you describe this problem, it's really not a problem with a single
device, but rather a problem with the system and network overall.
By the way, is this chart (it's the ack vs nak chart from PH) showing NAKs for each device when it
was the sender or responder? In other words, say I have two linked devices, a controller and a
responder. If the controller sends an ON signal to the responder, but the comms break down here,
does PH record that as a NAK for the controller or the responder in this case? This is an
interesting question (to me anyway) because some devices can only act as a controller (a
controlinc, for instance) and some devices can only act as a responder (a lamplinc for instance).
Would it make a difference with regards to troubleshooting? If I had a device that was excessively
higher than the rest with NAKs, might I look for different things if I knew it was having trouble
sending vs receiving?

I was thinking there were more than a few NAKs when I read "I noticed some red eventraw=05 log messages roll by". An ACK is sent by the device receiving a command, back to the device that sent the command. Device A sends a command to device B. Device B sends an ACK back to device A to acknowledge receipt of the command. Should device A not receive the ACK it will retry the command sent to device B. With the way the Insteon powerline works the PH2 PLM generally does not "see" the ACK that device B sends back to device A. It is on the powerline at the PLM but the architecture is such that the PLM does not pass out to PH2 Insteon commands/ACKs that were not addressed to the PLM. The net of that is the NAKs to ACKs are for commands the PLM sent to specific devices. That chart actually looks good.

Well, some of my devices have over 16,000 comm counts (wow, that sounds really, really high).
Yesterday when I was adding this new device, there was an eventraw=05 roll by about every five seconds.
I was probably rebuilding links for a good half hour. There were periods of time when the 05's weren't
rolling by, but there were other times when they definitely were.
Now that I have pretty much added every device that I probably can add, I should probably reset all of
my numbers. But then again, it is probably good to keep track of older devices and trend their
performance as they get older.
By the way, I am still using a PLC (not a PLM) and I do have one set of signalincs installed.
