Connect the In-Wall Transformer (0,99in x 1,38 in x 0,79 in) to the Netatmo Video Doorbell and connect it to the existing electrical wires hidden in the wall. To make it even simpler, there's no need to install a chime.
Requires electrical know-how.
The Netatmo Video Doorbell rings on the smartphone and, if you want, on a compatible smart speaker. The Transformer is specifically designed for the Netatmo Video Doorbell.
