Three-phase Hybrid inverter but system showing only one phase

I'm new to Victron so I'm actually not sure if my question is more about Victron configuration or MQTT-device driver.

Anyhow, I've set up my 3phase hybrid inverter in VenusOS using https://github.com/freakent/dbus-mqtt-devices

I'm at the point where I have the device showing up on dbus, all the values are being populated and updated. In VRM I am able to display power, voltage and current values for all three phases on Ac In and Ac Out sides. But the system is still showing up as 1 phase and only displays L1 values natively.

This is what I'm seeing on dbus for my inverter:

And when I check under system, I only see L1 values and number of phases is set to 1:

Also, everything is looking good when checking the Remote Console:

systemcalc provides the system values which are generally used for power numbers rather than looking at the individual inverter services. It seems system calc only looks for a single phase for services starting with com.victronenergy.multi. Multiple phases are processed for services starting with com.victronenergy.vebus

It looks like this should be showing up as a service starting with com.victronenergy.pvinverter since this is a PV inverter NOT an DC to AC inverter or inverter/charger.

[Edit] I had a look at the Dryer Hybrid inverter and it looks like id qualifies as an inverter/charger. But systemcalc only supports a single phase device for com.victronenergy.multi...

The author of the driver probably needs to have a discussion with someone at Victron to sort out the best way to handle this.

Thank you very much Kevin! Switching to vebus type populates the values correctly. But vebus type comes with a different issue - now com.victronenergy.system service seems to be constantly restarting. All values keep flickering in and out every second or so.

Check the systemcalc log. There's probably something the Deye Hybrid inverter driver isn't putting on dbus that systemcalc expects.

There may be a better way to make this work than having the Deye Hybrid inverter impersonate a Victron VE.Bus inverter/charger but it's beyond what I could help with.

Thank you so much for your help again Kevin. Turns out it was not the vebus service but since vebus can not handle PV stuff, I split my PV information into a separate solarcharger service. And that is what's causing the system service crash.

I need to dig deeper into that one.
