Bridge the C1/V contacts and wire the Doorbell and Chime-Module to the other 2 like it was a 2-wire chime.

And if your chime doesn’t play the Melodie til the end then, as my Grothe did, you need an relay in addition...

👍

Maybe one day there will be an option to set a „minimum ringing time“, no matter how long you push.

Hi Philip,
can you elaborate on the relay a bit more ?

Did you simply use a 8-12V magnetic relay (that can drive free-flow output) and use that as the "chime", and connecting the chime module with the relay ?
The free-flow contact would then be used to trigger the Chroma (in whatever from Chroma supported power/trigger configuration ?)

Thanks,
-Markus

Hi!

I did it as shown in this Thread https://forum.netatmo.com/viewtopic.php ... com#p81965 and used the same Relay as GEORGzer - but for 12V instead of 220. Hope this helps!
