Tesla hardware module

[JPSke]

Hello JanJaap, thank you for the hard work. After a long time there again is hope that communication with the car will be possible through domoticz.
My remarks are not in any way criticism or meant to push you. I only want to keep you posted about possible issues. My experience so far:

Downloaded version 0.6.0 and the errors are gone, as you said. The devices "Charge level" and "Range" are updated regularly, The switch "Charging" also, but never goes "on". Stays off all the time even when charging the car is started in the Tesla-app. The other two "location update needed" and "remaining charge time" do not get updates. I changed the names of all devices because my car's name is a long one and it did not fit the controls, but I saw in the log that my new names appear in the list, so I think that is not a problem. Hope to hear from you soon,kindest regards JP

[JanJaap]

Hi,

I'm really happy with all feedback. So I won't take it as criticism nor will I ever feel pushed . I try to check if everything works as expected but I miss things too. So please keep reporting if something isn't working as expected or if you have an idea for more functionality.

Btw I just pushed version 0.7.1 with several improvements, o.a. fixing the issues you mentioned. The only thing I can't fix at this point is the location update, as it is not coming from the Tesla server. The TeslaPy library would need an update for this. As Tesla are changing their server interface, I might need to switch to using an other library at some point, but am not going there yet, as those aren't as nicely documented as TeslaPy......

[JPSke]

Downloaded 0.7.2 and for testing purposes put 1;1;1 as polling intervals. Would expect to get new values every minute, but this does not happen. Last update was 9:13 this morning.
To be really useful, we must be able to switch charging on and off (to make efficient use of produced solar power). Do you see this possible to be implemented? Also nice to have would be to control the charging amps (as can be done in the car and in the app).

[JanJaap]

Hi,

The Tesla server limits the amount of requests in a given time frame (not uncommon to prevent overload) so there is a lower limit to the polling interval (I think it will be something like 5 minutes but not sure).

I will dive into using the other libraries that will allow sending commands but will take some time. I also want to do something with balancing the solar power with the charger (although I think my charger will be able to do that itself but it will only be installed next week). However, at this moment I guess you're solar panels are not producing nearly enough to charge the car

[JPSke]

Today the solar panels (11 kWp) produced 24 kWh and the home battery is 15,6 kWh, so there was some extra production to put in the car.
But the main raison why I need to control this is because here in Flanders we have that weird system where you pay part of the distribution cost depending on the average quarter hour peak value you produce. It is ± 40 Euro per kW, so if one has an average peak of 17 kW, which is not abnormal when charging a car while the heat pump, laundry machine, dryer and dishwasher are working, you pay around 700 Euro per year on top of the normal distribution costs, taxes and power costs. Peak shaving is very profitable, but to do so every heavy power consumer has to be switchable. I lowered the wall charger from 16 kW to 7 kW, but that still comes on top of the normal consumption, so it has to be switched off, when other devices start working.

[JanJaap]

OK, 24 kWh that is impressive, I was happy with 5 (the last months I hardly got over 1 kWh.....).

Given this payment system I see why it makes sense. Still, it will take some time as the alternative library is much less nicely documented as the TeslaPy library. But I'll give it a go. Might take some weeks though......

[JPSke]

Patiently waiting.... No stress!
On a cloudy day I only get 1 or 2 kWh, but when it is sunny in summer when the sun is high, I produce more than 40 kWh per day. Still need the power switch for charging because the car must only consume when there is enough and the home battery is nearly full.
Thanks in advance for your work.

The plugin stopped working. In logfile:

[JanJaap]

correct. Tesla deprecated the API that TeslaPy, the undelying library, is using. I'm investigating the upgrade. This requires different way of authentication. Takes some time.....

[JanJaap]

The latest version of the teslapy library has fixed this issue, you need to upgrade that one. I added a check in the plugin that the version of the library is new enough. However upgrading for me failed, so remove and reinstall of teslapy should do it

[JPSke]

Removed TeslaPy and reinstalled (version 2.9.0)
After putting in my e-mail address and running 'tesla_prepare' I get this:
Traceback (most recent call last):

[JanJaap]

Hi,

Then apparently not all needed chanegs came through, as line 375 of __init__.py should read this:
return [Vehicle(v, self) for v in self.api('PRODUCT_LIST')['response']] if v.get('resource_type') != 'vehicle']
Where the error above still tries to get ('VEHICLE_LIST')['response'], which is the old code.

Btw, I had to do both lines below:

Code: Select all

sudo python3 -m pip uninstall TeslaPy
python3 -m pip uninstall TeslaPy

As apparently it was installed in 2 location which were both in the path so it would fall back to the other when one was removed.

[JPSke]

Uninstalling twice did the trick. Now I get "authenticated your Model 3 called...." but after running 'tesla_prepare', there is no link to the browser as before (Use browser to login. Page Not Found will be shown at success. Enter URL after authentication: https://auth.tesla.com/void/callback?code=.....) and in Domoticz in the log it sais: Tesla: Initialisation failed, check log file and/or run tesla_prepare first

[JanJaap]

you need to pull the latest version of the plugin as there was a small mistake in verifying the version. And as you already have a valid cache.json so no need to do the trick with the URL anymore.

[JPSke]

Everything is working now. Thanks!

[JanJaap]

Just pushed a new (minor) update that catches some errors more nicely. Still working on integrating the new API to send commands, but it is slowly progressing. Partly because it ain't easy, partly because of other obligations. So stay tuned......

[edit] oh yeah I forgot, it now reads the actual location and not the destination......

[JanJaap]

To update on progress for implementing commands: I've got the new API working in a stand alone script that only retrieves data. This was quite an accomplishment already. Next steps are to get sending commands to work and then to integrate all of that into domoticz.....

[JanJaap]

Small progress update: based on the tesla api example I managed to get it to work almost till the end. I will get to work on integrating this into domoticz, but trying to get this example to work is a precondition for anyone who wants to have the domoticz integration. And yes, it takes some time, so you can get started......

@JanJaap:
Just today I discovered your plugin and thought I'd give it a try.

I'm using a headless Armbian 24.5.1 Jammy (Ubuntu).
I was able to install python3 libpython3-dev and python3-requests but there was no candidate for libpython3.7-dev so I install libpython3.11-dev

After this I was able to install TeslaPy 2.9.0.

Then I changed Elon's email address to that of my tesla account and ran python3 tesla_prepare but it just sits there with:

"HTTP request sent; waiting for response."

Any ideas what I might be doing wrong?

[JanJaap]

Hi Ian,

Not really sure what is going wrong (would help if you can post the command line outputs preceding the waiting) but one guess is that the tool is waiting for a response from either the Tesla server or your car. So you could try to run it again after you have accessed your car with the phone app to wake up the car.
