Hi,
i ended up in this article while looking if it is possible to use my existing chime and wanted to see if you have a good idea.
existing installation: have a netatmo smart doorbell installed with a traditional chime. Netatmo provide a small chime module to avoid having the chime ringing constantly. The wiring is like you see in the image, blue white cables come from the doorbell and the 2 small black ones are from the chime module. So when the doorbell is pressed the chime module allows the current to go also in the traditional chime and it rings
Future: Want to replace the netatmo with a G410 doorbell
Can i use the dual relay module or the single switch module to achieve the same result? Do i need external power to have any of the 2 modules from Aqara being able to work or can also just be in between and having the existing chime ring with an automation when the button is pressed? If it is possible, any suggestions for the wiring?
thank you
