Modular Hydraulics cannot be used with electrical system v1

Version: 1.2.7.0

Frequency: Consistently

Severity: High

Bug description:
The new modular hydraulics system cannot be used with electrical system version 1.
Any hydraulic pump or valve circuit will not be detected by the hydraulics systems and will lead to an error.
The only solution is to migrate to electrical system version 2, but for which reason?
This is not precised in the SDK documentation.

Hello @AZP

Can you try by providing CircuitIndex instead of Circuit (name) to your hydraulics components?

V1 of electrical system comes from MSFS 2020, where component names where not mandatory, and components were only referenced through their index.
We introduced indexing through names with MSFS 2024, as component index was no longer reliable in a modular context.

Let me know if that solves your problem.

Hello @FlyingRaccoon,

Indeed it works when using CircuitIndex.

SDK documentation is a little bit misleading as circuit names also exist with electrical system V1, so we should be able to declare hydraulics components using circuit names.
Is it possible to edit documentation to explain that Circuit parameter will not work with electrical system V1?

Thanks,
Romain

Yes, we will clarify this.
Thank you for the feedback

Hello @AZP

SDK 1.3.1 documentation has been clarified on this.

In the V1 (legacy) electrical system CIRCUIT_HYDRAULIC_VALVE still seems to be non-existent.

It’s also missing from the documentation for the legacy circuit types:

Compared to the modular (v2) electrical system where both hydraulic pump and valve circuit types exist:

Additionally I get this error message when using CircuitIndex instead of Circuit:

I don’t see how it could have worked for you @AZP

@RXN6085 Maybe there is another issue, I don’t know as we switch to electrical system v2 some time ago.

Kind regards.
