Hi
I have successfully set up Haaska and my echo controls my switches fine. My issue is that my blinds is set up as a switch in HA and will only respond to on/off and not open/close is there a way to fix this?
Check this video https://youtu.be/2R9M9u1AB2Q?t=395 and here is his repo.
I haven’t go through the entire code, but maybe it will be a good start for you. If you find it, please share it here 
Hmmm … looks like Amazon removed this capability in an “update.” I found some chats in Gitter explaining it.
