Add car from different account

[alexrusso51]

My wife just got a M3 with an account in her name/email. I am currently using TeslaMate with my MY. I want to add my wife's M3 to TeslaMate as well. Most importantly I want both to report as separate cars to my HomeAssistant MQTT broker.

I'm running TeslaMate as a docker container in a Ubuntu VM on Proxmox. I spun up a new VM (RancehrOS) and got the new M3 tracking in there. I have them both pointed to my HA MQTT broker which is running as its own VM on the same Proxmox box. Problem is, they both report to MQTT with a car id of "1". So I can only see one of them at a time in MQTT/HA.

Any suggestions on how to fix this?
Can I change the car_id for one of them? How?
Can I somehow add the new car to my original TeslaMate install?

Any reason you stood up its own TeslaMate instance for your wife Model 3? Your can run both inside of a single TeslaMate instance and each Tesla will have a unique ID. Data will stay unique and separate for both. In fact, if you ever have to log back into one or both instances, I imagine the other car is going to show up. Quite surprised when you setup the second instance and logged in, both cars did not show up.

Can I change the car_id for one of them? How?

You could manually through the database, but do not advise it.

Can I somehow add the new car to my original TeslaMate install?

You would need to be added to her Tesla account as a driver. Then it should show up in your Tesla app as a second car. Once confirmed, log out and log back into TeslaMate. TeslaMate should pickup the second car.

Edit: re-read your first line - did not pickup you used her email address and password. See here: https://www.tesla.com/support/account-support#car-access "How can I add a driver for my vehicle?"

My wife's car is on a different account with Tesla. My Tesla account is my email, hers is her email. They have different access tokens. How do I add my wife's car to my instance of TeslaMate?

I imagine since they are separate accounts only the one associated with the account the instance is logged in with shows up, and not the other.

See some of my later edits, totally my fault for missing that they were separate accounts. You would need to be added as a driver to your wife's Tesla account (linked in original response). Once you do that, her Model 3 will show up in your Tesla app. Once you have done that, log out and back into TeslaMate and her Model 3 will show up and have its own ID. Probably 2.

Thanks. Trying now. I'm already added as a driver for my wife's M3. Didn't think about logging out and in again.

Logged out. Now having trouble logging in, keeps telling me tokens are invalid even though I just generated them with the iPhone app.

Couldn't log in. Good old restart of the container did the trick. Everything working great now. The second car showed up. Thank you for your help!!!

I am in a similar situation -- I have a non-primary vehicle show up in the API, for me, because I have an access_type of DRIVER (my spouse's vehicle). I've noticed that some data that shows up for my own vehicle is missing for my spouse's vehicle. Examples are

• Efficiency dashboard: "Consumption (net)" and "Consumption (gross)"
• Trip dashboard: "used" (positioned above "added (AC)", which is populated)
• Drive Stats dashboard: "kWh used" and "Median kWh used per day"

For the Trip dashboard, even if I view previous days (thinking maybe the day must be "closed out"), the "used" is still blank. All of those metrics are present for my own vehicle, with access_type of OWNER.

I'm sure there are others, but it seems like power consumption/usage is the core item not being recorded.
