I'm updating my Venus GX to Cerbo GX so it will now support a battery BMS and VE. can bus.
The Cerbo GX manual, section 12.1 Configuration Note for Digital inputs, "Pulse Meter is not supported in Cerbo GX." then give examples of configuring to "pulse"
What does this mean? I can configure all D1-4 as "pulse", and they do seem to count (sometimes) when I earth the Digital inputs - 3.3 Volts but not all pulses are counted.
It would appear if ground pulses are occurring in under many seconds between pulses the pulse counter is not incremented? Is this the correct operation?
What is the minimum ground pulse width needed for the pulse counter to count reliability?
Why the lack of backward compatibility in the more advanced and powerful Cerbo GX?
I used the pulse counter on the Venus GX to record water meter flows and rainfall (tipping bucket) which do not work reliably now on the Cerbo GX which is the replacement for the Venus GX. Can this be fixed?
If the Cerbo GX manual could be a bit more technically specific on the accepted pulse width for the reliable operation of the pulse counter would be much appreciated.
