upDown support? 
First off, this is great. I have had a sun shade running on 433Mhz that I REALLY wanted to get working with Homekit. This is doing the trick (as a switch) I was digging through the code and noticed up/down accessories are commented out at the moment. I would really like to be able to use the appropriate "open the blind" and "close the bling" language with Siri, I am hoping an up/down accessory would allow that.
