Caller ID INDICATES "Smart Home," which suggests a robocalling do-not-call regulation-violating entity seeking to entice you to give up info on utility costs while pretending to be a local utility-company "partner." They in turn will sell your info to low-life Southern Ca solar panel scammers, who will then be calling you hundreds of time in the next 6 months. Block number, report robocallers to donotcall.gov online or via phone.
