As a homeowner who recently upgraded to the Qolsys IQ Panel 2+ with the 345MHz add-on card, I’ve encountered an intriguing issue with my RE201 sensor setup. The sensor, connected to a magnet switch for my garage door, worked flawlessly on my old panel. However, post-upgrade, it’s been a bit of a puzzle. The panel detects the sensor, but once I open the garage door, it stubbornly remains in the open state, refusing to revert to closed unless I manually remove and re-add it. I’ve double-checked the wiring with an Ohm meter, and everything seems in order. The sensor responds correctly when the door opens and closes, yet the panel doesn’t see the state change. It’s a perplexing situation, and I’m eager to understand why this discrepancy is happening. I wonder if there’s a firmware update or a configuration tweak that could resolve this. Has anyone else experienced similar behavior with their Qolsys setup? I’d love to hear any insights or troubleshooting steps others might have tried.
