Ok, did the research concerning the NAK of the group cleanup messages and did find a bug. Excellent bit of detective work there guys  .
This actually is a problem for both the PLC and the PLM but is not as obvious in the PLC. It's not really a misinterpretation of the flags, it's more a lack of interpretation. What is happening is that PowerHome did not even check for the ACK of Group Cleanup messages. In the case of the PLC, you would see no NAK's or anything outwardly wrong. With the PLM, it operates a little different. When a Direct command is sent from the PLM, PH starts a timer waiting for either an ACK or a NAK. This includes a Group Cleanup message which is also a Direct message. If PowerHome does not receive a response before the timer expires, it adds an entry to the PLM log of Insteon NAK. Since PowerHome was never checking for the ACK of Group Cleanup, the timer will always expire and create an Insteon log entry for Insteon NAK. No other effect or error is caused by this other than an additional NAK count being entered against the device and skewing the COMM reports.
Since the PLC (and the SDM) has it's own internal ACK/NAK tracking, this bug caused no problems with the PLC. However, Ive gone ahead and corrected the error in both the PLC and PLM so it will be gone shortly.
Thanks for all the hard work guys and helping me to make PowerHome even better.
Dave.
