You could disconnect the wires at the smart button and see what you have then (assuming this is just a doorbell circuit)
Usually the power goes into the chime and they run a switch loop to the button. You should be able to ring the chime straight from the transformer leads. If that doesn't work you have a bad transformer or a bad chime.
I suppose you really should find the transformer and remove it if it is bad or at least remove power from it if it is hanging outside a box, buried in the wall and find an accessible place for a new one.

Is there any chance that the chime wiring has been run in parallel with higher voltage cables, causing an induced voltage at times?

So got into attic seems to be older type install with individual conductors run to each device, typical of older system installed with knob and tube era, where trans former is spliced off K&T wires and nailed to side of joist,

What are the chances you can just run fresh wire or use the existing with a regular transformer.

So rewired the chime and located new transformer in accessible attic, got 16 volt trans, read 20.4 at button contacts, chime still only strikes once, on front contact. could the chime be blown since only receiving 13 volts over time?

Is there a terminal for one chime and another for both?

Did you test the chime with the new transformer directly connected?
