We have one in the living room and one in each bedroom. I use it for
announcements to tell DD when tea is ready etc.
alarms/reminders of appointments, ie doctor, or to collect DD from somewhere
shopping list, you keep adding things and then it will read it back to you
to play music when I go to bed (Sleepwell Station)
DD plays music on hers from spotify, amazon etc
radio when working
daily quizzes, Friends, Harry Potter, Disney etc (not every day but when we are bored)
searching for tv "Alexa play Friends on Netflix" - although it only ever seems to go to series 1 episode 1 not where you left off watching it
to sing Happy Birthday/say Happy Christmas etc
timer for cooking
daily news/weather etc
Alexa can be a bit stupid though as my DD's name ends with an "ah" so often when I say her name, Alexa will pipe up instead. We did change Alexa's name, but that just caused confusion, "Alexa, no Dot, no Alexa!!" and so on, so changed it back. It is a shame that you can't choose the name, there are only 3 to pick from
I also use the Alexa app and am thinking about getting an Alexa tv but not sure on that one yet.
