I was super excited to get my August Smart Lock, only to discover on the fine print that it isn't compatible with Mul-T-Lock locks. However...both the August Lock and the Mul-T-Lock use rotation around a fixed axis to operate. So I created this design to adapt the August Lock to the Mul-T-Lock.
Install just as you would any other lock according to the August instructions, but use this adapter instead of one of the ones that come with the August.
This is designed to work with the Mul-T-Lock Hercular deadbolt, I'm not sure if it works with other Mul-T-Locks as I don't have any to test out. Also, this works with the august ASL-3B, I'm not sure which other August locks use the same design on the inside. If the plastic adapters have triangles on the sides, then this should work. If your August lock has straight lines on the side of the adapters, then this will not work (although it could be easily remixed to work with those).
