Sending Pulse to relay on battery charge/discharge kwh

Hi guys, I am hoping to send a pulse to a relay for an external piece of software to monitor total power in and out.

Is there an easy way to do this via a digital relay on the Cerbo or could I do this by a relay on either the battery monitor or the Quattro? If so, how would I go about configuring such a pulse?

Hook up 2 Venus pulse counter inputs from a bi-directional meter with discrete import/export pulse outputs.

Thanks, and how do I configure the pulse itself? Or is there a default ones available out of the box for input and output to batteries?

What Phil is talking about is a way for Venus to count pulses from another device via one if it's digital INPUTS.

I think you are asking about the opposite: get a Venus output to pulse so you can count those pulses on another device. This functionality isn't available

There are however many different ways to get information out of Venus. I'm not well versed in these but they are: ModBus TCP, NMEA 2000, MQTT, command line interface to dBus. Then for the "large" Venus software, Node Red and Signal K.

Yes, I was.

My suggestion will still hold true, to provide pulses to any external unit. however, it is an AC solution. I have never seen a DC solution.
