Reading more standard NMEA2000 devices

Do anyone can explain how we can read more standard NMEA2000 PGNs on Venus OS?

For example this device:

https://acrossoceansystems.com/wp-content/uploads/Datasheet-AC-Monitor-AOS.pdf

The device outputs all power parameters Voltage, Current, Hz, Power, Power factor, etc., and can be connected to a generator or shore power and possibly displayed on Venus to be monitored if one does not have Victron Inverter.

I don't understand why the system will not read more PGNs. How difficult will that be as it is already reading and writing from the NMEA2000 bus?

The PGNs that AOS AC Monitor device outputs are

PGN 127744 AC Power / Current - Phase A
and
PGN 127747 AC Voltage / Frequency-Phase A

There is another device that can be used for alternator current monitoring:

https://acrossoceansystems.com/wp-content/uploads/Data-Sheet-DC_AC-Current-Sensors-AOS.pdf

this one outputs PGN 127508 for current

These AOS devices also have WiFi connectivity and can be connect to the WiFi network and provide data over the network for integration with AOS.

There must be a way to add more devices to Venus OS
Can someone please explain?

@Jeroen I read some of your posts and I see that you are more familiar with NMEA2000 then the majority of the users. Can you guide me in the right direction and modify Venus OS so it can read the devices mentioned in the post?
