That’s cool. I’ve been wanting to do something similar with a MimoLite. Seeing your pics got me off my (you know what) to try it. It Worked! I just wired the two leads to be power to the MimoLite. And since the mimo can be configured to send notification on power off, it trips a millisecond after the bell riings and power is lost again. What’s nice is it won’t take batteries. Here’s a pic. I have the same bell as @Johnny_Davy and it looks like the plastic box on one side can be cut out to accept the mimo.
I’ll post more as I tinker
