Same issue here. Daydream Lenovo Mirage Solo (+ 1 Daydream controller paired with the Mirage) + 1 WiiMote + 1 Daydream controller connected to Win 10 + iVRy & Steam VR + Kinect.
Daydream controller paired with the Mirage is detected as “iVRy Controller” and appears in the right position and is working – but the buttons are not, they open the menus on the Mirage.
Wiimote (left hand) and other Daydream (right hand) controller appear far left behind me and off-center in Steam VR. Offset does not work and is terrible to use….pulling the headset up to see the monitor while breaking your neck to figure out where the controllers are in VR and using the mouse to move them.
