Fisher Panda integration and visualization

I have a system that includes the Fisher Panda DC generator connected over the CAN bus to Cerbo GX. The generator control works, and visualization and reading from the generator work well during the operation. However, when the generator is idling, it draws some power from the main batteries to power the built-in electronics. During that time, the consumption is indicated incorrectly on the Cerbo GX side.

Seems like the cerbo isn’t recognizing the negative value and, as a result, calculates an incorrect output power? Is there any way it could be solved?

That looks like a 32-bit number for power (in W) has incorrectly wrapped round (-18W to 4.294967278GW).

@M_Lange Hi, maybe you could help me find the right person to help and address the issue that looks like a software bug in the cerbo side
