Describe the issue

Integration: Teslemetry (Home Assistant)

Version: v3.0.14

---

Description of the Issue

The set_scheduled_charging service in the Teslemetry integration is failing to set a scheduled charge time.

This was previously working through Teslemetry, though I'm unable to remember exactly when it stopped working or which version. I previously had an automation configured using the old Owner API integration, migrated it over to Teslemetry/Fleet API, and it then continued to work for some time before recently stopping.

Reproduction steps

1. Call the set_scheduled_charging service with the desired parameters.
2. Observe that the scheduled charging time is not applied.

---

Expected Behaviour

The service should successfully set the scheduled charging time for the vehicle.

---

Actual Behaviour

The service call appears to complete successfully, with no errors raised. However, the scheduled charging time is not set on the vehicle.

---

Additional Notes

• I have tested the new calendar option introduced this week, but it also fails to set a scheduled charge.
• I reviewed the latest release notes and noticed that this issue was acknowledged, but I could not find any related GitHub issue.
• I am currently using version v3.0.14.

Debug logs

I'm working on replacing this with the newer API endpoints. They are currently in 3.0.14 but I havet got them working for my vehicle yet.

See the calendar entities.
