Hi
If you are in for a DIY,
I have seen it is possible to pair universal relay module receiver 433Mhz to the Reolink doorbell.
Is it allowed to post Youtube links here? I can post the link to the video if you want.
I would like to test this very much because I would like to install the doorbell at my parents house.
But would like to use there original chime this would be possible with this method.

Edit: Maybe it is possible to pair a universal 433mhz chime ? Idk
