Hi everyone, my security system occasionally shows a sensor as offline even though it seems to be working normally. Has anyone experienced this, and what troubleshooting steps helped fix it?
Offline is a common status indicating that the sensor is having trouble reaching the panel with its heartbeat supervision signals. We have a guide for troubleshooting the Offline malfunction below.
Depending on the panel model and type of sensors that you have, there may be specific alternate causes. For example, if you have a Qolsys IQ Panel and you are using legacy RF sensors (319.5Mhz, 433Mhz, or 345Mhz), the internal RF sensor antenna in the panel may not be routed out the back of the panel properly. That will cause intermittent difficulty with sensor signals.

Thanks, @Jason. That gives me a few things to check. I’ll try replacing the battery, power cycling the sensor, and checking whether anything might be affecting the signal. I hadn’t considered the range or panel antenna before, so I’ll look into those too. Hopefully one of those fixes does the trick.
