Ioniq Ev Support

Hello everyone.
Is Ioniq EV compatible whith Ovms?

Thanks everyone.

Hi there,

Hi there,

I used to have an Ioniq EV and have same friends with that car and they are interested in the OVMS module. Does anyone know if it works?



I'm afraid the Ioniq is not

I'm afraid the Ioniq is not currently supported 



Let's make it compatible!

I suggest that we set up a group of enthusiasts to develop the support for Ioniq EV. I am in!

What would be the steps to develop this?

Is there a guidance on how to get started somewhere? OK, found it on https://www.openvehicles.com/developers

but I am still a bit uncertain if OBD-II would be enough for Ioniq to get the basic functionality working (such as State of Charge, Start / Stop charging, pre-heat)

I have understood that no documents regarding the CAN(?) bus commands for Ioniq has been released by Hyundai so we'd need to somehow reverse engineer the traffic.




Anyone making progress?


not yet

I have received the hardware, but no progress yet. I tried to collect logs, but as Ioniq is not on the vechiles list, didn't succeed.

Shall I compile my own firmware to get Ioniq on the vechiles list? I'd appreciate guidance on how to get started.

You need to install the "edge

You need to install the "edge" firmware release to get the Ioniq.

The .bin file for firmware update

Can you tell me where to download the .bin file for update, in order to select Hyundai Ioniq from vechiles list? Now I have selected the vehicle type "Kia Niro / Hyundai Kona EV" and I can receive some data about my Ioniq (2020 38Kwh) and I can even lock / unlock the car.

From the web interface, show

From the web interface, show the config firmware page, and set the release tag to 'edge'. Then do a normal OTA update.

Ioniq 2020 - 38kwh

I managed to successfully connect my Ioniq (model 2020 - 38kwh) to OVMS hardwere and I can confirm that it works. In the web interface I configured the car like Kia Niro/Hyundai Kona and the data is correct, except for the estimated range. I failed to change the battery capacity from 64000 wh to 38300 wh and from here I think this error occurs. I can lock and unlock the doors, check the state of charge, check the location of the car, TPMS. I can't set pre-heat conditions and I can't start / stop charging, but I'm convinced that in the future it will be possible.
In this way, I would ask those who know how to add the 38kwh Ioniq as a separate car and solve that battery bug.



How did you get it to lock/unlock?

Did you do any changes at all or did you just install the edge firmware (released at that point in time when your post was written 18 june, 2021) and used the Niro/Kona-profile?

I installed OVMS v3.3 2022 hardware with the latest edge ota, 3.3.003-2-gd00de6c0/ota_1/edge (build idf v3.3.4-848-g1ff5e24b1b Sep 3 2022 11:34:32), but I can't get it to lock or unlock. I can see the different information, like TPMS, different temperature and SoC. But lock/unlock isn't working at all and the charge speed and ideal/estimated range is wrong even if I have changed the battery capacity in the battery config settings.

Kind regards


Edit 2022-09-22

I had not enabled CAN writes before. With enabling CAN writes by typing "config set xkn canwrite yes" (without "") in the Shell, in web interface, or Messages, in the android app, I enabled CAN writes and the lock and unlock function now works. HOWEVER... When unlocking the car and opening the door the alarm goes off and you have to turn it off with the car key or by pressing the button on the car door.

Ioniq 28Kw

soy propietario de un ioniq, y he comprado recientemente el ovms. Estaría dispuesto a si alguien quiere mejorar el firmware para este vehículo, permitir conexión remota a mi portatil conectado via wifi al ovms para tomar datos del coche e intentar mejorar las prestaciones para este coche.. mi telegram es @freelock76

Un saludo.



So all the functions work

So all the functions work with the Kona profile, except battery and estimated range. Has there been anyone successful in getting the battery and estimated range to be correct?

Since the Kona profile/firmware already works, isn't the process to get the battery and estimated range working pretty much "copy/paste" and edit the excisting Kona profile somehow? There has to be somewhere to edit the 64 kWh to IONIQs 38 kWh battery capacity.



is it possible to lock / unlock the Hyundai IONIQ vFL 28KWh, when it is in drive mode and the key is not inside the car? That is very important for me.

Thank you!

best regards,


Is there nobody that has the

Is there nobody that has the IONIQ 28KWh and can test this for me?

Thank you!

best regards,


The car is "drive mode" and

The car is "drive mode" and the key not inside the car? Why is this good?

Just was developed by Michael

Just was developed by Michael the estimated range and TPMS function for Ioniq 28. Now have in the "edge" firmware

Because its nice when you

Because its nice when you want to leave the ac on or charge devices over usb until you are back at your car when you have a little break.

So can you lock and unlock the Ioniq 28 kwh over OVMS? When its in drive mode or not?

What about remote climate? Thats a thing I really miss in my Ioniq. :-(

Thank you!



No it is not possible, and

No it is not possible, and remote climate is also not possible.
There is only battery monitoring at the moment.

Ioniq 28Kwh - ovms "xhi"

Ioniq 28Kwh - ovms "xhi" model

@philos31 , @DobbyNator94 , @Tozs

I have tried to use the "xhi" profile and have executed the command " config set xhi canwrite yes " and then restarted the ovms box.

I am still not able to lock/unlock the car.

Is it possible and if so, which vehicle profile should be used instead of the Ioniq vFL (28KwH) profile ? Kona 64KwH and then adapting the battery info/range info ?

Won't that mean that the individual cells info will be incorrect though ?
Would the Kia Soul 27Kwh/30Kwh not work, it seems that lock/unlock is supported.?
