Elausys knx/Solar edge gateway

Has anyone actually configured one of these gateways ? Whilst I am able to read some data from the Inverter via the Gateway in ETS5 ac voltage&Current,DC voltage&current, cabinet temp,lifetime output etc (Obj 3,7,14,15) I am not able to read the group objects for AC daily energy yield (obj 40) and  powermeter (obj 55). Elausys chat line and telephone enquiries are not answered.
