Echo Speaks and Follow Me setup

Hello,
Can anybody please help me setup Echo Speaks and Follow Me? I am not able to get them working. I have alexa echo devices in my house. In case of notification, I am trying to make them speak "e.g. possible intrusion... or backyard door open" .
Am I supposed to give Echo Speaks, as the output of Follow Me somehow?

Echo Speaks:

Follow Me Home - child app

Follow me Away - child app

You might have better luck getting responses from their respective topics. I would start by asking the question in the Follow Me one.

Thanks. Will do.
