I have reason to believe that the currently shipping Insteon Open/Close Sensor 2843 no longer has a Heartbeat signal. Either that or I have 4 recently purchased defective sensors, or who knows what else might be going on.
I have 10 Open/Close Sensors (2843-222), 6 of them are REV 1.B installed a couple years ago, and 4 are REV 2.1 installed recently.
On the ISY 994i, when I look at the Administrative Console Main tab, all of the REV 1.B have the Current State of the Heartbeat node showing "On" at all times, while all of the REV 2.1 show “Off”. I’m using a program to constantly monitor each of them. The REV 1.B sensors respond every 24 hours with a Heartbeat signal. The REV 2.1 sensors never respond.
Thoughts anyone?
