I have tried both Aeotec (original and Series 5) and UZB sticks, and I have found the UZB stick more reliable with a better range and richer features.
So, I am intrigued by their new offering https://z-wave.me/products/z-station/
As the UZB stick is currently supported, I hope this new Z-Station will make it to the Indigo-supported list. I am getting on the pre-order list to get one, just in case Matt feels inclined to make it happen
