Nutone KB-10 doorbell + Shelly Uni

    I want to make my Nutone KB-10 doorbell smart using a Shelly Uni to be able to do the following:

    1. Receive notification when the doorbell button is pushed.

    2. Trigger the doorbell chime remotely for alarm purposes, etc.

    3. Disable the doorbell chime when I do not want to be disturb but still receive notification when the doorbell button is pushed.

    How do I wire the Nutone KB-10 and Shelly Uni?

    Thanks

    Obviously, the doorbell has two flavours, one for each pushbutton (front and rear door). Do you want to use this feature?

    It would be brillant to measure the electrical resistance between terminals „trans“ and „front“ and „trans“ and „rear“! Is the chime driven by batteries or by a transformer? A picture of batteries or transformer would be nice!

    This is essential for the implementation of Shelly.
