Hi,

I'm designing a board that will have to embed the Opentherm interface.

The website www.opentherm.org doesn't say much.

I'm looking for schematics or hardware specifications.

thanks for any help,
Enrico

It says all you need to obtain the protocol:

For that matter, it says you have to be a member of the association to
sell products commercially -- and presumably if you're a member you can
buy (or get for free) the full spec.

These two things are more or less orthogonal: the specs can be obtained
free of charge.

The reason why the obtaining of the specs and the licensing are left
separate is because a lot of the members of this industry may have the
development of the electronics outsourced and this companies do need to
become members (although it helps to be in).

hi,

thanks for your answer.

The protocol specifications (version 3.0) I got from the site don't
say much especially about the hardware interface.

It's a 20-page document and I guess they are just a brief summary of
the full documentation.

I browsed the web and couldn't find much, except: http://openingupopenthermprotocol.nl
