IP22 and grid tile

Hi all,
I have a IP22 and a EDECOA inverter.
I wrote a driver for my edecoa inverter reading data from a tasmota plug and it is working well.
For the IP22 I added the ve.direct port and connected it via usb to my raspberry. I can see the IP22 data in the device list.
as it is a “com.victronenergy.charger” I was expecting to see the “grid” tile in the main dashboard gui-v2 but nothing appens.
So I was thinging to aggregate the inverter with the charger to create a dummy acsystem device but I’m not able to get any results
I configured the acystem as :slight_smile:

            '/Devices/0/Service': {'initial':  "com.victronenergy.charger.ip22"},
            '/Devices/0/Instance': {'initial':  52},

            '/Devices/1/Service': {'initial':  "com.victronenergy.inverter.tasmota"},
            '/Devices/1/Instance': {'initial':  295},

I can see them in the rs devices but no sum calculation appens.
what am I missing?
is it possibile to do something like that?

thanks
