Ioniq 5 "Unknown Error" when scheduling charge

[rebuilder]

Region and Brand of car
EU Ioniq 5
Version of the integration
2.29.0
Describe the bug
I'm trying to schedule charging using the functionality newly provided byt the integration. To do so , I'm running the "Kia Uvo / Hyundai Bluelink Schedule charging and climate" action from developer tools in HA.

I've enabled the target vehicle (tried without as well), scheduled charging, first departure and time, the off-peak start and end-times of course, as well as tried with climate control set on. In short, I've tried with a wide variety of options toggled on and off.

All that happens is I get the error "Failed to perform the action kia_uvo.schedule_charging_and_climate. Unknown error".

Does anyone have success using this feature?

[asychow]

Tested on my end that if no data is supplied, schedules are turned off (although you may get an error in HA log saying 'action not found', but the request went through). Here is the yaml I used

action: kia_uvo.schedule_charging_and_climate
data: {}

Can you post the yaml you tried to run (hide the device id)? I may be able to point out anything that is off.

[rebuilder]

I tried the yaml with no data as you showed, still got the same error and no change in the schedules on the car's end.

Here's an example of what I tried to run:

action: kia_uvo.schedule_charging_and_climate
data:
  charging_enabled: true
  first_departure_enabled: true
  first_departure_days:
    - "0"
  first_departure_time: "07:00:00"
  off_peak_start_time: "01:00:00"
  off_peak_end_time: "02:00:00"
  off_peak_charge_only_enabled: true
  device_id: [censored]

[rebuilder]

I tried running the close charge port action, also got an unknown error. My automations that start charging, climate etc continue to work though. Not sure what's going on now.

[asychow]

Your script works on my vehicle, therefore I guess your issue is model specific ...

It is worth noting that actions which work on your vehicle use
SPA_API_URL and self._get_authenticated_headers

Actions which don't work use
SPA_API_URL_V2 and self._get_control_headers

Would you be able to capture what BL sends for the not-working-actions?

[rebuilder]

I'd be happy to try capturing, but I don't know how :D Is there a guide somewhere?

[asychow]

I had some luck with proxyman, but there is plenty of alternatives

I'm also getting an "Unknown error" when running any code using this service from the developer tools, eg

action: kia_uvo.schedule_charging_and_climate
data: {}

If I write a script to run the service, I get a slightly different "controlToken" error, shown here in the script trace:

Error: 'controlToken'
Result:

    off_peak_start_time: '19:40:00'
    off_peak_end_time: '19:50:00'
    off_peak_charge_only_enabled: true
    climate_enabled: true
    temperature: 21
    temperature_unit: '0'
    defrost: true
    device_id: [hidden]
    first_departure_time: '07:30:00'
    second_departure_enabled: true
    second_departure_days:
      - '0'
    second_departure_time: '16:00:00'
  target: {}
running_script: false

Here are my details:

Describe the bug
Trying to run the schedule_charging_and_climate service always fails.

And the details from my log:

Does it work in the native app?

[cdnninja]

I think this is based on the new vs old APIs. Maybe year based. Could those with the error post the year and model of the car? Also interested to hear the same for those that it works for.

[b3uk]

Does it work in the native app?

Yes scheduling works in the Hyundai app.

And I made a mistake before - it’s a 2020 model Kona that I’ve got.

I have an MY 2022 Ioniq 5

I was able to capture the BL POST request for setting the charge time, here’s the JSON part of it

Content-Type: application/json; charset=UTF-8

{
  "reservFlag": 1,
  "offPeakPowerInfo": {
    "offPeakPowerFlag": 2,
    "offPeakPowerTime1": {

        "timeSection": 0,
        "time": "0600"
      },
      "starttime": {
        "timeSection": 0,
        "time": "0110"
      }
    }
  },
  "reservChargeInfo1": {
    "reservChargeSet": true,
    "reservFatcSet": {
      "airTemp": {
        "value": "24.0",
        "hvacTempType": 1,
        "unit": 0
      },
      "airCtrl": 0,
      "heating1": 0,
      "defrost": true
    },
    "reservInfo": {

      ],
      "time": {
        "timeSection": 0,
        "time": "0700"
      }
    }
  },

    "reservChargeSet": false,
    "reservInfo": {

      ],
      "time": {
        "time": "1200",
        "timeSection": 0
      }
    },
    "reservFatcSet": {
      "airCtrl": 0,
      "airTemp": {
        "value": "24.0",

        "unit": 0
      },
      "heating1": 0,
      "defrost": true
    }
  }
}

I can also provide the test of the request data If you need it, it’s not quite clear to me how much of that is safe to post publicly.
