you're not able to recognise when you're talking b*****ks
So the people who developed ebus ( as in Energy Bus ) are also talking b******ks then.
Sorry but unless plumbers and heating technicians actually know how the ebus physical layer works they really should not be passing judgement on people who do.
One person who does know all about eBus was a founder member of the original eBus User Club which was founded 20 years ago. I do not think he would be talking b*****ks
