My experiences of late, this was my first time setting up Echo and install the VERA plugin with associated Skills;
I finally was successful in get the skills defined but I seem to have a little trouble getting the app and helper file to download properly on to my Vera without an error messages (I notice it whilst watch my Vera status at the top of page). It would download the app but I would get error downloading the Alexa Helper file, after three or four times of it trying to download (by its self) it finally downloaded however the Vera Plugin Installation page indicated "failed" even when I depressed the "Retry" button (bottom of Panel). Once my Vera indicated that it down loaded the plugin satisfactory (no messages) I again depressed the "Retry" button and was finally presented with "Finish" button.
I then went to the Amazon Alexa home page under the "Smart Home" tab I noticed that I now have "Vera Smarter Home Control (BETA US)" being displayed under the "Your Smart Home Skills" and after selection "Discover Devices" under the "Your Devices" it was successful in detecting both my Vera devices and scenes that selected whilst in the Vera Plugin Installation Skills. I noticed that it doesn't like hyphenations or pound symbols in the names.
I too have notice that when I ask Alexa to turn ON/OFF any of the Vera devices I'm presented with "Sorry, Light device is not responding" message then 7-8 seconds later the action is performed (light comes ON or OFF). Is this normally or is there something I need to do?
Also why doesn't the Alex Helper App create a device that one can see in their device(s)?
