Saul Morse had no idea when he equipped his house with smart home products that they would prove potentially lifesaving. The 78-year-old, who has post-polio syndrome and uses a wheelchair, had connected the Amazon Alexa in his bedroom to his contacts list, so when his wife had a stroke in their bedroom one night, and his phone was in another part of the house, he was able to use voice control to phone his adult children, who in turn called 911.
