[RELEASE] Hyundai Bluelink Remote Start/Lock Support (Beta)

[WindowWasher]

Lock and Unlock use a different URL. I was thinking the same thing. Maybe the 2022s that didn't support climate seats all use the same URL. The new API was tested on a 2025 Ioniq, which supports the climate seats. I'll send you a PM with instructions to hack your copy of the app to use the original URL. It's an easy edit. That will be later. I have to go take care of the Trick or Treaters now.

Hi everyone,

Figured I should probably introduce myself. I'm another Hubitat dev/tinkerer that recently bought a new 2025 Ioniq 5, and I am VERY interested in more automations in the car. WindowWasher has created an awesome app that allows for Bluelink control, so I've asked him if I could help update the app to support newer vehicles and their more advanced features.

We currently have a branch of the app and drivers where we're iterating on and testing some of the newer features and supports. I'd appreciate anyone who is willing to test this branch, and I am open to feedback on how to make it better or if something isn't working properly. Just grab the latest App and Drivers and install them, then go to your Vehicle and click the Refresh button so it can detect the newly supported features.

Some of the latest updates include:

• Start/Stop climate controls now work for EV.
• New EVBatteryPluggedIn attribute for EVs, to help detect when Climate Start will pull from the charger.
• Major climate control upgrades:
  • Heated Steering can now be controlled separately from Heated Rear Window and Mirrors.
  • Heated/Cooled seat controls.
  • Climate profiles are now per-vehicle and auto-detect supported features for that vehicle.

My current favorite part of this upgrade that I'm using liberally is that I can now use Hubitat to schedule more times to automatically warm the car before trips (since my kids have different schedules each day of the week), since the car defaults to only two programs. The app upgrade also allows more fine-tuned climate controls than before, so you can fully configure your heated (or cooled) seats if your car supports it. And if your car does not support these features, the app auto-detects that and will not pollute your climate settings config with settings you cannot use.

Anyways, nice to meet you all.

Sure, would love to test that beta release. The native Blue link app actually doesn't extend heated seat options for the 2022 Ioniq 5, so I'm wondering if it can be done over API instead? As I mentioned above, the EV specific Blue link features/attributes from the 2025 model do not work for the 2022 model.

Yeah, like WindowWasher says, if Bluelink can't see it, we can't see it. If Bluelink CAN see it though, our app will see it. So can try the beta branch and see what it can see?

@amorley

I mentioned the sensitive info only because I'd like to contribute to making these features work with the 2022 Ioniq 5, and I know posting these logs can be compromising, so I'd like to help where I can.

@WindowWasher

What we can do is use PMs for posting logs instead of the general thread and you can also manually redact info.

I completely agree and it's on my list to look at cleaning up. In the beta branch, I've already changed the storage of password and PIN to type "password" so it's not easily accessible to others on the hub. I'm thinking about adding a new option to allow for redaction of sensisitive information in logs. The issue though is that the logs are most valuable when they are untouched, and Bluelink is pretty bad about not separating that info out themselves. But I think I can do something to make the logs good enough to share. But this will need to wait until after the climate profile work is done.

@amorley

502 is usually a bad gateway error, so I thought perhaps the server was having an issue, but lock/unlock commands are working just fine, just the EV Start/Stop commands arent.

You mentioned that you were trying to use a different API for start/stop for EVs. Perhaps the 2022 model requires the original API URL instead? If you can give me a test version to try out, I'll check it.

Any chance you're the same person that reported this issue on github? For everyone else's context here, there was another issue reported where vehicleStatus was also failing to parse. In the main branch, if vehicleStatus doesn't successfully parse, EV detection fails, which means the wrong API will be used to issue to the Start command, which is probably what's causing the 502 error. This issue is now fixed in the climate-profile-work branch and I encourage you to try that version.

[amorley]

Yes, I also posted each of these issues to the GitHub in separate threads for sanity of tracking all of this

I just tried your branch, and I'm still getting Hyundai Bluelink App -- Start vehicle failed -- status code: 502: Status: 502 on my 2022 Ioniq 5.

This fixed my 502 error on remote start! I have a '26 gas limited. This changed the status of Engine status for me (before it was always Off) and Is EV (which reported True before, now it is false).

The remote lock and location worked fine. Now I can remote start, it behaves with the climate profile. I am testing the remote start for period of longer than 10 minutes now. The new UI allows up to 30 which hopefully works because in winter that is typically closer to what I need here in the Midwest.

THANK YOU!!

@kevinb What version of the beta are you using? We pushed a new version yesterday. Look at the App file, line 46 to see the App version. The latest is 1.0.7-beta.climate.4.

Glad it's working with a 2026 ICE vehicle. We hadn't had anyone with that flavor of car testing. What is your car, a Palisade?

I have my doubts as to setting a longer duration will work, but try it and let us know. I believe that Hyundai limits it for either safety or liability reasons. I usually do 2 remote starts in sequence to work around it, as my 2022 Palisade will not even be close to warm after 10 min.
