Smart deadbolts, the Australian edition

I want to fit a smart lock to my glass sliding door but the distance between the sliding door and the sliding fly screen is only 40mm. I have searched all over the place and cannot find anything that will fit. Has anyone seen anything that might fit? I would prefer a knob to a handle.

The other alternative is to get a Yale Unity Screen Door Lock to go on the sliding fly screen. I am pretty sure that it would work but it is my second preference. I am also not sure if I would need to purchase the bridge that comes with it. What can be done with this lock in HA with and without the bridge? Can anyone comment on this?
