Readings from ComAp InteliLite 4 AMF25 controller are wrongly presented in VRM

Hi there :)


It will be nice if someone from Victron Stuff can take a look on potential bug(s).

In InteliConfig, it's possible to change units scale, like on screenshot below:

When Power Format is set to “Small 0,1kW/kVA/kVAr 1V”, VRM portal shows that “Generator” and “AC loads” power values are 10 times greater than they should be (screenshot below, left side). ComAp controller reports correct value in InteliConfig (screenshot below right side). Tried with Venus OS 3.13 and 3.20~35 – no luck.

I also found ComAp Python script on GitHub and suspected that maybe rounding is doing that wrong (screenshot below).

One more question:

Generator Engine operating hours are shown in seconds on Widget. Is it possible to change to hours? We need it for precise generating monthly report.

Hi @cika8, thanks for reporting. I assume that we were not previously aware of this setting option. Two questions to fully understand the situation:

  • Can you confirm, that the reported values on the GX device and VRM are correct, as long as the Power Format setting is set to "Standard"?
  • Is there an important reason for you to change the setting to "Small"?

Regarding the operating hours: I will forward your request to the VRM team.

Hi @Philipp Trenz :)

Thanks for answering. Answers are below:

1. When power format is set to standard, everything is fine.

2. The reason why accurate readings are preferred is because our Investor asked is that option possible - primarily aesthetics.

Hi @cika8, I'm afraid, we are not planning to add support for the "Small" power format. Please also note, that according to the instructions, it seems to have no effect on "Genset kWh" (Communication Object 8205), which is used for measuring produced power. It therefore does not lead to greater accuracy in reporting.

Hi Phillip. :)

Thanks for answer. Now, we are waiting for "Generator Engine operating hours" fix on VRM.

Best regards.
