No verbal command is needed to use this skill or the Sentinare sensor. This skill is designed for use with US Sentinare accounts, located in the US. Also, your Amazon account must be subscribed to the Alexa Together service. With this skill enabled, any fall incident detected by a Sentinare sensor will trigger your Alexa Echo devices to ask if 24/7 Urgent Response is needed. After successfully linking with a US Sentinare account, skip the "Discover Devices" step. You do not need to use the Alexa app to discover or manage Sentinare sensors.
