Amazon Echo Flex is a clever devices that you can spread Alexa every where in your home. It is because your house gets many power plugs and spread widely. This is really a plug and play device without any cables.
Users can use this devices to control their smart home via Alexa. the reason is that Ehco Flex gets a tiny mic and speaker which is not suit for playing music or other entertainment. If you have Alexa enable lights or thermostats, you can speak to Alexa to control them.
I think the most suitable places of Echo Flex are hallways, laundary, main door, as it can be a complementary device for the whole Alexa system. People won’t put the expensive version Alexa device, like Echo Studio, to that places.
Moreover, there are USB accessories for Echo Flex. They are a night light and a motion sensor. That why echo flex is perfect for hallway and main door, as you can make something automation when you pass by.
