Help with Home Assistant and Alexa

Tags: #<Tag:0x00007f32680c38b0>

I configured Alexa integration using this guide:

Configuration seems to be ok, and if I run lambda test from AWS console, it list all my entities.
BTW when I open Alexa and I activate the skill, it find only 2 lg WebOS TVs and none of my covers or switches are listed.

What I’m doing wrong?
