Sorry for the remedial question but here goes: I was looking for a Life Alert style monitor for my 89 year old mother - lives with us - but I know that she wouldn’t use it because she wouldn’t want to be a bother. (Seriously - if she had fallen with a broken hip she would wait for us to come home.) She needs something where she can contact us or 911 but it has to be hands-free. Bad arthritis and failing vision rule out a cellphone. I know that some nursing homes are outfitting rooms with Echo Dots but the issue is probably the same. Would she need to have a functioning iPhone with its own data plan to make a call with a HomePod? What about an IP call? What about an iMessage with WiFi? Or something else? Siri/Alexa would have to pick her up from all of 6 feet away so that should be fine. Thank you.
