Just found this. These two are free and there is also a paid subscription service called Alexa Together which provides a really comprehensive service.
1. Alexa Emergency Contact (Free)
This feature allows you to designate one person as an emergency contact who will be alerted when you say, "Alexa, call for help" or "Alexa, I need help".
How it Works: When triggered, Alexa attempts to call and text the designated contact.
Setup: Open the Alexa app > Communicate > Contacts > Emergency Contact.
Callback: If the contact misses the initial call, they can use the Alexa app to call back directly to the Echo device.
2. Alexa Care Hub (Free)
Care Hub connects your Alexa account with a loved one's account to provide remote, high-level, and private updates on their activity.
Activity Feeds: Caregivers can see when their relative first uses their Alexa device in the morning and their general activity level throughout the day, without seeing specific requests.
Alerts: You can receive alerts if no activity is detected by a certain time.
Drop In: It enables the "Drop In" feature, allowing family members to immediately connect to their loved one's Echo device to check on them.
