This might be a potential temporary work around for you....
As mentioned, I had some devices not show up via the Almond Smart Home skill.
I can't control these devices with "Alexa turn on Tree".
My work-around was two scenes in Almond.... scene 1 was called "Tree On" and in that scene I just have it turning on that Almond devices and scene 2 was "Tree Off" and in that scene I just have it turning off that device.
I found at that point, I had to have the plain Almond skill for scenes to work so I added that skill too.
Now, I can say "Alexa, tell almond to activate Tree On scene" and it works (I prefer to say "Alexa, activate tree on scene" but is seems to work only 50% of the time that way)
I do recall Echo did not like me naming scenes certain ways... like the 1, 2 thing you are doing and/or I tried to limit multiple syllable words/phrase.
Even though the device is not discovered by Echo, it can still run the Almond scene and the Almond scene recognizes and control its fine.
Not ideal, I know, but as a temporary work around while you work with Almond support it might get you going.
