Home screen still beeps after batteries replacement

You can’t. It’s an engineering issue, and unless you had a notification to change batteries in your sensor (?) you may of just replaced them for no reason. My beeping is unrelated to batteries in sensors. There’s no notifications on screen either, hence it’s only an issue resolved by engineering. Call Xfinity and open a ticket to engineering.
