I have two problems:
• Sometimes, when I stand just above an Alexa Echo or a Dot (2nd generation), and say "Alexa", and tell Alexa what to do, I get an answer (only) from another room, about 20 feet away (I have one Echo and three Dots). This started a few weeks ago.
• Today, I tried to connect my Ecobee3 Lite thermostat to Alexa on my Alexa phone app. I did what I read on line to do, but only one of the Dots can discover Ecobee.
So, I ask for help to see what I can do to reset or otherwise get everything to work. Note. I had Echobee working on all Alexa devices once in the past, but ...
Thank you for your help.
