This is interesting. The MB-Server reported that the action was executed without an error.

I don’t have access to a new CLA but asked a different user to test this with his car.

2706

In my car, I can start the pre-conditioning, but I don’t get a reply back - neither from HA, nor from the MB App.

2707

Yes, I have seen this as well and was surprised too. I checked it then in the Mercedes App multiple time, but it wasn’t working. Interestingly the direct start of pre-heating works well.
Note: even in the app I have often the issue the the first attempt of programming does not work, therefore I have made a repeat until … but even this doesn’t work (after 5 attempts)

2708

P.S. Happy to test, if you tell me how

2709

Hello, i installed the integration and it is working fine so far, but i do not get any location data. Car is MB CLA EQ, Firmware: None - GEN20XI3

Hi @Bluestar_01,

Please make sure that all digital services are active. I heard multiple times in the last days, that after the latest MBUX update not all services are reactivated. Please check if the car location is visible in the official app.

You will find the location in HA via the device_tracker…

If this does not work, generate a diagnostic report and debug log, and send it to me ([email protected]

I have published a minor bugfix release v0.34.2:

:lady_beetle: Fixes

  • Fix charging break clocktimer failing for midnight (00:00) times (#395, Thanks @alexpalmer)
    Fixed a bug where setting a charging break timer start or stop time to 00:00 (midnight) would silently skip the timer entry.

Hello, I’m having a problem with the window display on my 2019 V-Class. When one window is open, the display shows “closed,” and when all windows are closed, it shows “open.” Is there any way to fix this? Thank you.

Hey @infotechhamm-cyber ,

may I ask you to open an issue on GitHub and please share all the requested details esp. the diagnostic report.

Did you changed the setting “show as” of the sensor (binary_sensor.xxx_windows_closed) to “window”? If yes, then this is the reason… Please share a screenshot to better understand the context.

Hi @all,

I’m looking for users of this component who are using an EQV, EQE and the new CLA 2025. In case you are interested to share your car data with me, please send me an email [email protected].

This will help me to test the component with real live data…

Hi there, I’ve been using you (great btw) repo for 3 years now, but recently after last update I got an error “No masterdata found. Please check your account/credentials.” so I deleted all my integration, reinstalled it but yet it still occurs - pls help me - what do I do wrong? I have to add it one more time - everything worked fine until last update - yes I check my MB account it’s fine.

2717

Hey @elp85,

“No masterdata found” means that the MB server did not delivered any relevant data.

I would propose that you open an issue in the GitHub repo. Add as much as possible information about your car, region, HA-debug-log, latest car updates.

We can discuss it there…

Hi all, I’m noticing an inconsistent success rate of actions triggered through the integration, reaching the car.

Over the last days, when an action is triggered from the integration (e.g. charging break configuration, preheating,…), most of the time it does NOT reach the car.
However, when triggering the action again (within seconds), it will reach the car most of the time.

I’m not sure whether this is related to the integration, as I don’t see any difference in the logs for the successful and unsuccessful calls.

On the other hand, doing the same action in the Mercedes app is successful at first try.

Is someone else noticing this behaviour? Any fix or workaround?

Please create GitHub issue with a debug log of multiple executions and share diagnostic output too.

I‘m travelling until end of may. Please expect slower answers.

@kapchin , @willembuys - thanks for creating the issue and providing the logs.

I have published a beta version v0.36.0-beta.2. This release contains a fix for this problem. May I ask you to install it and check.

Solution:
Fix: Allow car commands to bypass reconnect cooldown
Car commands sent during the 60s reconnect-watchdog window were silently
dropped by call() because is_stopping was still True. The cooldown is
intentional for background traffic (429 protection) but must not block
user-initiated commands.

Add _force_immediate_reconnect_for_command() helper that cancels the
pending watchdog and clears is_stopping. call() now uses _unloaded as
the real shutdown gate, drops only background traffic during cooldown,
and forces an immediate reconnect for car commands.

I have a GLA250e
Is there a way to detect if the car is home (in the garage) ?
Before I did this with the tracking feature, but recently I decided not to pay anymore for this extra feature (expensive !) ...
... using a Wifi connection maybe, if the car is home, it connects to the home Wifi, and by pinging this IP address detecting this ?
... or any other way ?
