Looks like this has now been merged, so just need to wait for a release with this element in it.

It is in the beta release in Play now, but the only problem is that with that version the possibility to go into “native” mode to get to app settings has disappeared. So the sensors cannot be enabled as of now, waiting excitingly for a new beta to be released.

With the 2023-08-03 app release, you can also choose specific entities now…
Which means still no dashboard…
I remotely help a friend to get his polestar 2 displayed, so I can’t test it myself

Now I’m confused… Just checked and compared the apple Vs android settings and not just didn’t had the Apple app no update since 4 month, but it has no sensors to select for cars etc…
Current best way:
-
“Install” Car Stats Viewer
-
Create a webhook to push information from “Car Stats Viewer” to HA
Following the hint above about the Car Stats Viewer app, which I had completely missed, I have been able to get information about my Polestar 2 in to HA. A lot of the info is in German (as the app is from Germany), but this is the process.
-
Sign up for a Test Track. The current list of tracks is here: CarStatsViewer Informationen - Polestar Wiki - Polestar Club (Google Translate will work on that page). Use the Google Account attached to your car.
-
Wait. I got a notification when I was added to the list, but you may not. Either way, you have to wait at least 24 hours before you can download the app. If you do get a notification, wait another 24 hours.
-
On your desktop, use the link supplied to accept the invitation and then use the option within Google Play to install the app on to your car. This shouldn’t take long.
-
In the car, you can find the app and configure it appropriately.
-
In Home Assistant, create a new template file:
templete:
- trigger:
- platform: webhook
local_only: false
webhook_id: averysecurecode
sensor:
- name: "Polestar 2 Altitude"
state: "{{ trigger.json.alt }}"
unit_of_measurement: 'm'
icon: mdi:altimeter
- name: "Polestar 2 Temp"
state: "{{ trigger.json.ambientTemperature }}"
icon: mdi:thermometer
unit_of_measurement: 'c'
- name: "Polestar 2 Battery Level"
state: "{{ trigger.json.batteryLevel }}"
icon: mdi:battery
unit_of_measurement: 'w'
- name: "Polestar 2 Charge Port Connected"
state: "{{ trigger.json.chargePortConnected }}"
icon: mdi:ev-plug-type2
- name: "Polestar 2 Ignition State"
state: "{{ trigger.json.ignitionState }}"
icon: mdi:car-key
- name: "Polestar 2 Latitude"
state: "{{ trigger.json.lat }}"
icon: mdi:latitude
- name: "Polestar 2 Longitude"
state: "{{ trigger.json.lon }}"
icon: mdi:longitude
- name: 'Polestar 2 Current Power'
state: "{{ trigger.json.power }}"
unit_of_measurement: 'mW'
icon : mdi:speedometer
- name: "Polestar 2 Gear"
state: "{{ trigger.json.selectedGear }}"
icon: mdi:car
- name: 'Polestar 2 Speed m/s'
state : "{{trigger.json.speed}}"
unit_of_measurement: 'm/s'
icon: mdi:car-speed-limiter
- name: 'Polestar 2 SOC'
unit_of_measurement: '%'
state: "{{ trigger.json.stateOfCharge }}"
icon : mdi:car-electric
- name: "Polestar 2 Timestamp"
state: "{{ trigger.json.timestamp }}"
icon: mdi:clock-time-eight-outline
Change the webhook_id to something of your own. Remember that you will have to type it in on the car, so make it easy to type. I usually use Word.Word.Word (three words with a period between).
The above is based on a post in the German forum, but the values were incorrect, so I have adjusted them.
-
Do a refresh of template entities in Developer tools, and verify you have a number of sensors starting Polestar2 with an unknown value.
-
Back to your car. The URL you need to enter in the webhook depends on how you are exposing HA to the internet.
If it is direct, then enter the value thus:
https://hostname:8123/api/webhook/averysecurecode
If you are using Nabu Casa, then you need to enable it in the Home Assistant Cloud config. It will be called something like "Trigger Update Coordinator (template) and choose to enable it. This will give you a URL. You need to get that URL to the car. It is a bit long to type, so what I did was email it to a webmail account, then open the account using Vivaldi browser and then copy and paste the URL in to the app.
Make sure that you enable the API and enable location tracking etc.
Once values are coming back to HA, you can do some more work in HA…
To use the location information, create a new Automation - just create the automation, switch to YAML view and then copy and paste:
alias: "Polestar: CSV Location"
description: ""
trigger:
- platform: state
entity_id:
- sensor.polestar_2_latitude
- sensor.polestar_2_longitude
condition: []
action:
- service: device_tracker.see
data:
dev_id: polestar_csv
gps:
- "{{ states('sensor.polestar_2_latitude') }}"
- "{{ states('sensor.polestar_2_longitude') }}"
mode: single
That is a very basic entry, it can be expanded with other information such as the battery charge.
Conversion of some values to something more friendly?
sensor:
- platform: template
sensors:
polestar2_speed_mph:
value_template: "{{ (states('sensor.polestar_2_speed_m_s') | float * 2.237) | round(1)}}"
unit_of_measurement: "mph"
friendly_name: "Polestar 2 speed MPH"
- platform: template
sensors:
polestar2_charge:
value_template: "{{ (states('sensor.polestar_2_soc') | float * 100 )}}"
unit_of_measurement: "%"
friendly_name: "Polestar 2 Charge"
- platform: template
sensors:
polestar2_power_kw:
value_template: "{{ (states('sensor.polestar_2_current_power') | float / 10000000) | round(2) }}"
unit_of_measurement: "kw"
friendly_name: "Polestar 2 Power kw"
Then finally a card to just show everything.
type: entities
entities:
- entity: sensor.polestar_2_altitude
- entity: sensor.polestar_2_temp
- entity: sensor.polestar_2_charge_port_connected
- entity: sensor.polestar_2_ignition_state
secondary_info: last-changed
- entity: sensor.polestar_2_latitude
- entity: sensor.polestar_2_longitude
- entity: sensor.polestar_2_current_power
- entity: sensor.polestar_2_gear
secondary_info: last-changed
- entity: sensor.polestar_2_speed_m_s
- entity: sensor.polestar_2_soc
- entity: sensor.polestar_2_timestamp
- entity: sensor.polestar2_speed_mph
icon: mdi:car-speed-limiter
- entity: sensor.polestar2_charge
icon: mdi:car-electric
- entity: sensor.polestar2_power_kw
icon: mdi:speedometer
Map card works well, particularly with the auto_fit value.
Mini Graph Card is good for the altitude value.
Only bit I am missing is converting the timestamp to human readable format, but I have an open question elsewhere on this forum on how to do that.

So for anyone else following along, the last entry in the template for the timestamp should be changed to this:
- name: "Polestar 2 Timestamp"
state: "{{ trigger.json.timestamp | multiply(1/1000) | timestamp_local }}"
icon: mdi:clock-time-eight-outline
That will convert the last date and time of the update to something readable.
You can also add this line:
- name: "Polestar 2 Last Update"
state: "{{ trigger.json.timestamp | multiply(1/1000) | timestamp_local }}"
icon: mdi:clock-time-eight-outline
device_class: timestamp
Which will give you a read out of the time the last update occured.
This is great, but somewhat complicated. HA in the car already exposes some of these sensors across the HA implementations (like location), could HA in the car be updated to expose all the same sensors that car stats viewer exposes?
As I understod it, it already does, but since you cannot get into the app settings in the car anymore ( after complain from google ) you cannot enable them. I thought this was only a temporary change but I seams permanent.

Those are some great modifications. Thanks for updating my work - mine was very much early stages and needed cleaning up, as I knew it could be done better.
I prefer the sensor for the Charge Port Connected, as it states True, which I think is more true to life.
Your modifications also allowed me to remove some of the additional templates I created as well.
Are you on the International Polestar Forum? If so, you might want to post your mods on there as well.
Not an active user there.
Feel free to link from there to here 
(thus avoiding duplication)
I just want to leave this here:
It seems some heros have developed exactly what we are all looking for, but for the Volvo environment. I think it would just be a matter of branching this to Polestar and we’re all set (with a rock solid integration not relying on 3rd party integrations and intermediary apps).
Perhaps someone here could port it? Alternatively help me petition the creator to help branch their creation to the Polestar environment!
Cheers
//S
AFAIK we do not share the same backend
Do you have access to your car information through a webpage ? Like volvo’s do ?
Clearly there is an API since companies like Tibber can develop functionalities towards it (Polestar Smartladdning – Ladda din Polestar smart ⚡️ Tibber), but it’s likely not public.
The only access I have, as you well know, is through the Polestar App.
edit: my thought was the Polestar API likely shares a similar internal structure to the VCC API.
A new version of Car Stats Viewer has been released, although it isn’t on all of the tracks. New functionality in the API, but the old one works as before.
Hi @scriven33
I am using your templates and stuff in Home Assistant. They mostly work great but I don’t seem to get any Lat Long or Altitude data. I’ve checked ABRP is working and the blue connection icon shows in CSV. Any ideas?
Have you enabled the option in CSV in the car to send that information? I am sure it is a toggle (not with the car right now).
