Hi Matt.
Thanks for checking w/ Insteon, etc.
While I haven't tracked the rev 44 modules explicitly, I think it's safe to say they were all working (issuing heartbeats) previously, and then all seemed to fail together. In fact I have since increased the heartbeat timer to 78 hours, and they have not expired. I've been searching for a reason why I seem to have intermittent issues w/ heartbeats from Insteon leak sensors (~20) and Insteon open-close sensors (~20), and recently it turned out that all of the rev 44 leak sensors failed (time expired) at the same time, which seemed odd. All are reasonably close to the modem, and have good batteries.
I checked several of the rev 44 leak sensors and they seem to include group 4 links. Here's the log output you requested, for one of them:

As I said, I've had intermittent heartbeat issues for virtually all of my battery-operated devices. I guess I can increase the timer value to try and weather more misses, but I wish I didn't have to do that. Could be an issue w/ the server—a new Mac Mini that is basically only running Indigo—but nothing I could detect. Perhaps it's server/Indigo load issue—does that seem plausible? I have almost 400 devices, 650 triggers, 200 schedule items, 230 action groups, and seven control pages.
Thanks again.
