I've seen a lot of questions here, where an ET112 does not show up on a Venus system. In nearly all cases the conclusion is a defective meter. But in all cases it seems to be working on the CG-Software.
We are facing the same issue and basically everthing is 'easy' to replace, except for the meter.
How did you diagnose the faulty meter?
Is there a way to prove, that all other parts are working?
