Describe the Issue

Buenas tardes, principalmente agradecer la integracion ya que es perfecta proporcionando los datos del vehiculo.

Simplemente comentar que en mi MG 4 no consigo activar la calefaccion para calentar, es decir por mucho que suba la temperatura siempre sigue en modo "frio".

Tambien probe a activar el "ventilador" pero siempre termina en modo "frio"

English:
Good afternoon, I would like to thank you for the integration, which is perfect for providing the vehicle data.

I would just like to say that in my MG 4 I cannot activate the heating to warm up, that is, no matter how much I raise the temperature, it always remains in "cold" mode.

I also tried to activate the "fan" but it always ends up in "cold" mode.

Buenas @foncubierta

Gracias. A ver si a la vuelta de Reyes lo puedo mirar y solucionar. Creo que hay algo específico de cada modelo que tengo que mirar, por el rango de temperaturas y funcionamiento.

I will have a look after new year. There's something specific about each model, regarding temp ranges and API call.

Cheers

Buenas. Con el MG ZS EV ocurre lo mismo. Al activar la climatización se pone en frio (AC) a 14 grados y no deja su variación.

Hello. The same thing happens with the MG ZS EV. When you activate the air conditioning, it goes to cold (AC) at 14 degrees and does not allow its variation.

En cuanto pueda lo miro. A ver si doy con una solución al tema.

Same for me in the UK. Blower turns on but heat is not applied. To be honest does the same in the not so iSMART app too.

I'm sure months ago I had a defrost button but that disappeared with an update which is annoying when it's now frosty outside.

Hi everyone,

In all honesty, I am having a hard time getting this sorted. Been trying some testing and end-up on the same issue. The iSmart App shows as ok and the temperature correctly set (on my vehicle), but also in cool mode when getting the check from the API.

If starting the conditioning from iSmart I get a status 2, but when doing the same from the Integration I get a status code 3 (AC cool mode). I may need some more days to get this fixed. I will try to get it managed for next release.

Hi,

Same issue on my MG4. But I was wondering... when I turn on the front defrost in HA, it turns on the front defrost button in the car AND the AC button. And it's heating up!

Don't really know what I'm talking about but, is there anything you can analyse in the front defrost automation in order to understand where the problem comes from ? I remember you wrote somewhere that the front defrost is set on 22° or 21°.

If you can't find the way to solve the heating problem with the AC automation, maybe could you use the front defrost automation with the possibility to set up the temperature ? (even for me 22° is fine).

Hi @simonsupakru

The call on the API for the Climate and the Front Defrost is separate and not correlated. So I cannot use one to get to the other.

I believe I am close to the solution. Next week I shall get this sorted.

Cheers

So over the last couple of weeks its been frozen/cold. As a test i tried some different things

1. only enable Front Defrost (this option isnt available in the MG app) = Lights turn on, Front Defrost on, Heating blowing but unknown temp however warm. Front screen is defrosted. Noticed however the switch in Home Assistant isnt instant, i guess it waits back for a response from the API.
2. only enable the Rear Defrost (this option isnt available in the MG app) = Same as above
3. Enable both Front/Rear Defrost (this option isnt available in the MG app) = I get a timeout occasionally, maybe trying to send too many requests at the same time. But eventually both front and rear enable and car is defrosted and warm.
4. Climate, set to 30 (max) and blowing (NO AC) = lights turn on, no defrost is done and cold air blowing only.

There is a setting in the MG4 to enable rear defrost when front defrost is enabled but from my testing it doesnt seem to work when triggered remotely.
