I just looked at Bsuer's website, yes, as of now, they only list the NE model but if you look at the smartphone screen shot, it shows connection to NE-BLE2 and EM-BLE2
So I would presume there is an EM model coming soon.
I also noticed something interesting in their product support page where is shows the buttons and says 1 button for 1 or 2 (1|2) etc. So use the same button for 1 or 2. I have used the dual number buttons before and on those, you enter a 1 by pressing the left side of the button and 2 by pressing the right side of the button. That is *probably* the way the Bauer buttons work also, but you wouldn't know that from their support page. IF the support page is correct, you only have 4 x 4 x 4 x 4 (256) possible combinations. If like the Ford keyless, then you have 8x8x8x8 or 4096 possible combinations.
Just saying...
