Hardwire Smoke/CO alarm with built in Alexa

Hi, I recently moved into a new home and discovered that the smoke/CO detectors are hardwired. I know in some towns hardwired smoke/CO detectors with battery back up are required by local codes. I installed 6 first alert smoke detectors that are compatible with ring but they are only battery powered. If possible for piece of mind a hardwired version would be great. I know Ring offers the detector listeners but I think some people myself included don’t like the look of having to hang another device next to a standard smoke/CO detector.

Does Ring have plans to make a hardwire smoke/CO detector with battery back up? This device could also function as a speaker and Amazon Alexa echo device all in one. I think a lot of home owners would appreciate the clean look of an Amazon Echo/Smoke/CO unit all in one that can be mounted to a ceiling. Thanks for your consideration.
