So my g4 started acting strange. I’ve had it for a few years. All the sudden the doorbell and repeater started going off like a siren. I can still ring the doorbell even while siren is going off. The only way I can shut it off is to remove it power source. I don’t have anything set up in automations or not using as security. Just was using a regular old video door bell
Thanks for any ideas
Hello @jford951
Welcome to the official Aqara forum.
Please check how securely your doorbell is secured. If the mounting screws are too loose, the switch responsible for alerting if the doorbell is tampered with or stolen may not be fully engaged, and the siren will sound. Is your lock secured to a level surface? Try loosening the mounting screws slightly.
