When i read u48CurrentSummationDelivered attribute of Simple Metering Cluster, the return value is zero.

 

When i read u8MeterStatus attribute of Simple Metering Cluster, the return value is right.

 

So I think the problem is that I can't read attributes that are larger than 4 bytes in size.

Is there any way to solve this problem?

 

 

There is my code:

Base on project “JN-AN-1218-Zigbee-3-0-Light-Bulb”

Init variables
