Good day all,

Studying right now the architecture of a BEMS and HEMS system, I was wondering which are the best communication protocols/interface for a BEMS system with an HVAC?
The first one to come in mind is an OPC server, but since is an expensive method, I was wondering if there're more of them?
Thank you

Alain
