Battery Low Alert on Wired Door Sensors

Hi everyone, I’ve been experiencing a peculiar issue with my wired door sensors. They’ve started showing a low battery alert on three of them, which is a bit concerning since they’re wired and shouldn’t rely on battery power. I’ve double-checked the connections and everything seems fine. Has anyone else encountered this before? I’m curious if it could be a software glitch or perhaps a faulty sensor. I’d love to hear your thoughts or any troubleshooting steps you might suggest. Thanks in advance for your help!
