Do UPB wall switches report status every hour?

Since I have installed my SAI US2-40 wall switch, I have noticed this X10 traffic in my home automation software log files:

12/28/2005 5:51:16 AM~!~X10 Received~!~C2 (?)  C Off
12/28/2005 6:50:33 AM~!~X10 Received~!~C2 (?)  C Off

The only thing I can think of is that this is the new UPB switch I installed, reporting back every hour what the status is, since it uses the C2 device ID in the Elk M1 (which has both the X-10 and UPB interface), and translates UPB to X10 and X10 to UPB. It seems to be happening every hour. The UPB appliance & light modules don't seem to be doing this, so I am hoping someone can confirm, this is normal behavior.

To my knowledge the M1XSP serial expander is not polling yet, so it must be a switch update. Interesting!!

None of my switches do this... but it's possible they've added this capability. If they have, I would bet there is a configuration setting you can adjust in Upstart.

I know SAI watches this forum, maybe they can give their opinion when they see this thread. It doesn't bother me since I don't have anything on C2 (I learnt the hard way to avoid UPB ID overlapping X10 codes in the M1 lol), but thought it was interesting. I am doing some experiments now to confirm this.

I have monitored my system via the Elk SDK and I do not see any PLC update messages unless I manually control switch. Have monitored for almost 2 hours. That's with 8 US240's. Must be something else or some setting that may be different.
