Ron, what I get out of the manuals is, the keygo io is intended to be paired with a motor directly.
So I doubt if you can pair it with a Connexoon box.
On the other hand, there are multiple remote’s which can be paired directly to Homey; With them you can start a flow and start anything you’ve connected to Homey.
F.i. CoCo AKCT-510
But I don’t know your concerns about the safety aspect
