Compatibility with ELVOX 7558

[vekexasia]

Ciao,

Congrats on the project. looks good.
I'm currently using the ring intercom to have some kind of smart functionality on my own elvox 7558 intercom.

I never was able to find which kind of protocol it does use I was able to find this manual but it does not seem to say much more than 2-wire-"plus"-bus?

Hi, there aren't many specifications available about that bus.
I found that it works with 27v power and my board is compatible. Consumption is also compatible with that required.

To understand more, it would be necessary that someone who has this intercom system does some tests to understand what goes through that bus and try to decode the protocol.The reception part of my project should be compatible, unless you have to change some components. The decoding part of the protocol should be done from scratch.
