Mercedes Me

waider · August 6, 2025, 7:17pm

Hmm. installed 4.3.7 from marketplace yesterday. For some reason it reset my location to North America. Fixed that, and it said I needed to auth but the auth endpoint wasn’t actually running. Disabled and reenabled and it came up successfully with no auth required. Today, unfortunately, it’s back to “Websocket Exception: Reason: Failed to upgrade to websocket: Unexpected HTTP Response Status Code: 429 Too Many Requests”

The only things logged in openhab.log are from around the time I installed the upgraded version but I’m wondering if it didn’t actually upgrade. I’ll restart openhab and see if it’s reporting the correct version.

waider · August 6, 2025, 7:38pm

Nope. On restaring the plugin wanted a password from me, and when I entered it I’m back to the 429 error.

update:

OK! some progress.

I had a phantom install of 4.3.3.nnnnnn which didn’t appear to be doing anything but could not be removed from the UI. I had to resort to the console to get rid of it, and there was no trace of it other than its appearance in the module list, so I don’t know where its jar file actually was.
On removing and reinstalling 4.3.7, I now have: “Login failure, check credentials. Failed to login. HTTP 200 {result:GOTO_LOGIN_LEGAL_TEXTS”. I’m going to assume this means I need to manually truck through a login to the Mercedes website and acknowledge some legalese.

update

logged in manually via a browser, went back to the plugin and toggled it on and off, and now it’s working. I’ll see if it’s still going in 24h, per previous experiences. Thanks for the work you put into this, Bernd, and if there’s anything additional I can share to help debugging let me know.

weymann · August 6, 2025, 10:12pm

Check 2 directories

/usr/share/openhab/addons if you manually copied a jar
/var/lib/openhab/marketplace/bundles/which contains numbers but within the jar with correct name is located

Btw, if you had two times the same binding running i would prefer to cleanup (like you did already) and perform one reboot. Otherwise there’s still the chance old stuff is connected

Sure, if everything is running with one binding installed you can enable TRACE log level then you’ll see more what’s happening.

If the car stands still and isn’t charging you’ll see lazy updates like this every refreshInterval

While driving/charging websocket Websocket is active for frequent updates

ulrgaer · August 11, 2025, 7:51pm

Is the 4.3.7 SNAPSHOT the one with the 429 error fix ?

Is this running on openHAB 5 ?

weymann · August 11, 2025, 8:06pm

Both yes. Official fix for OH5 is in review!

ulrgaer · August 16, 2025, 4:55pm

Hi Bernd, I have the snapshot running since 5 days. It’s working perfect. Thanks for the fixes. Uli

dk8pn · December 6, 2025, 2:05pm

Have now upgraded my computer and openHAB to 5.0.3 and everything works out . Many thanks to you for all your work and especially for providing me OH 3.4.6 versions of your binding for my Intel Compute Stick with a rather limited performance while this OH version was already outdated. Am really happy now to have carried out this step.

Wish you a nice Advent time.

anne_hh · January 24, 2026, 9:18pm

Since some weeks the binding is offline. Reason:

Pretty sure the password hasn’t changed and i can still login via browser to mercedesme. Anything i could check?

weymann · January 24, 2026, 10:15pm

Ok, let’s see. First I need some more infotmation.

Which OH and binding version. Any logs?
Was it running before and went offline?
Did you try something for recovery e.g. disable/enable thing?

Especially after enabling some trace logs are helpful.

anne_hh · January 25, 2026, 9:24am

Oh, of course. Sorry.

Yes, it was running for months and went offline somewhen i December. I first didn’t recognize it because we were not at home, so i don’t know when exactly.

Running openHab 5.1.0 and Binding 4.3.7 from Marketplace.

Yes, disabled it (had to, because it broke my MercedesMe Account by hammering wrong passwords) and couldn’t reenable it because of that.

So there is no token?

weymann · January 26, 2026, 12:11pm

Just as side note: There’s no need anymore to take the Marketplace binding. All changes are in OH5.1.

No token available because login fails:

Your usename is accepted in Step 3 so this is correct
Step 4 the real login reports error Login 401 - {“errors”:[{“key”:“errors.login.fail”}] so all points out the password is wrong.
Please triple check - any typos or password changed during the last weeks.

anne_hh · January 26, 2026, 1:26pm

OK, used the openHAB official plugin, worked like a charm. WTF….but anyway, thanks so much for your help

dk8pn · April 28, 2026, 7:31am

Have a CLA 220 4-matic “mild hybrid”. It has a small electrical motor (48V) integrated into the gear. Its battery doesn’t need an external charging.

Now to my question: Is this vehicle still covered by “combustion” w.r.t. this binding?

weymann · April 28, 2026, 4:31pm

Yes. If you have this already and the vehicle is visible in your MercedesMe app on your account isn’t there a new thing discovered an put to your inbox?

dk8pn · April 29, 2026, 5:28am

Thanks for your quick response. The car is already active in the MercedesMe App but no new thing has been discovered in OH.

weymann · April 29, 2026, 9:39pm

Please check /var/lib/openhab/jsondb/mercedesme.json. Is there an entry with your vehicle vin xxx-features?

dk8pn · April 30, 2026, 12:35pm

Yes, for the VIN there is the following entry:

"xxx-features": {
    "class": "java.lang.String",
    "value": "{\"features\":{\"auxHeat\":false,\"bidirectionalCharging\":false,\"chargingClockTimer\":false,\"controllableRearWindowBlind\":false,\"controllableSunroof\":false,\"convertible\":false,\"dcCharging\":false,\"distronicPro\":false,\"doubleDoorLock\":false,\"driverAssistancePackageHigh\":false,\"driverAssistancePackagePlus\":true,\"ecoCharging\":false,\"fastCharging\":false,\"hepaFilter\":false,\"hybridEncryptedPictureTransfer\":false,\"mopf\":false,\"nacsToCcsAdapter\":false,\"pictureTransfer\":false,\"pluggedStateDependingPreEntryClimateControl\":false,\"precondNow\":false,\"rearSunProtectionBlinds\":false,\"remoteHornSingleHonk\":false,\"remoteSettingPersonalizedTemperature\":true,\"remoteSettingTemperature\":true,\"twinTire\":false,\"urbanGuard\":false,\"variableOpenableSunroof\":false,\"variableOpenableWindow\":true,\"weeklyProfile\":false},\"vehicle\":{\"acMaxChargingPower\":null,\"baumuster\":\"178347\",\"changeYearCodes\":[\"056\"],\"chargingSocket\":null,\"controllableSunroofBlindsCount\":null,\"dcMaxChargingPower\":null,\"dcMaxDischargingPower\":null,\"digitalVehicleKeys\":[\"APPLE\"],\"doorsCount\":4,\"doorsHandleType\":null,\"drivingSide\":\"LEFT\",\"electricVehicleType\":null,\"electricWindowLifts\":[\"FIRST_ROW_LEFT\",\"FIRST_ROW_RIGHT\",\"SECOND_ROW_LEFT\",\"SECOND_ROW_RIGHT\"],\"fuelTypes\":[\"GASOLINE\"],\"headUnitSoftwareVersion\":\"SOP\",\"headUnitSoftwareVersionRaw\":\"SOP\",\"headUnitType\":\"GEN20XI3\",\"mbOsVersion\":\"MBOS_VERSION_1_0\",\"modelYearCode\":\"806\",\"powertrainBatteryModel\":[],\"productGroup\":\"PASSENGER\",\"remoteSeatConfiguration\":\"EACH_SEAT_INDIVIDUAL\",\"starArchitecture\":\"STAR3_5\",\"sunroofType\":null,\"tcuType\":\"ARTEMIS\",\"tirePressureMonitorType\":\"TIRE_PRESSURE_MONITORING_SYSTEM\"}}\n"
  },

It seems to run still as combustion, similar to my last A 220 d. Is this conclusion right?

weymann · May 3, 2026, 12:18pm

Features looks good. Did you already try to create a combustion thing manually with your vin?

dk8pn · May 5, 2026, 7:45am

Created a combustion manually. This works out . Many thanks.
