Thinking of buying an Echo Dot from Ebay when one comes up at a good price, most likely it will be used and connects to wifi so that Alexa can talk to you and play music/radio. I plan to replace my clock radio at my bedside as Alexa can play the radio and set alarms. Only problem I can see is the Echo will be set to someone else's wifi and I dont fully understand how the Echo is set up, I presume it is via the Echo's own wifi so you can set it to pick up your own router's wifi.
Can anyone see any problems with my plan, technical or otherwise?
