Vehicle not detected when multiple vehicles configured

[Macrisu]

Hello!
Until two days ago I had only an EV: a Mercedes EQC
Now I have the second EV: Tesla Model Y, LR

If I have only Mercedes config, the car is recognised and SoC is working.

If I add Tesla in the config when I connect the EQC, the car is not recognised, no error from what I see in the logs.

I can log in from the evcc web interface for EQC, with no errors.

Here is my evcc.yaml:

network:
  # schema is the HTTP schema
  # setting to `https` does not enable https, it only changes the way URLs are generated
  schema: https
 
  # host is the hostname or IP address
  # if the host name contains a `.local` suffix, the name will be announced on MDNS
  # docker: MDNS announcements don't work. host must be set to the docker host's name.
  host: xxxxx.go.ro
  # port is the listening port for UI and api
  # evcc will listen on all available interfaces
  port: 7028

Moved to vehicles.

no error from what I see in the logs.

As I wrote before. Please show the logs.

To make the log readable you could remove any modbus/influx/cache etc. It's not relevant here.

Imho what's happening is is that the EV is already connected and detection completed when MB login happens. It should work when you un/replug after MB has been authenticated.

[Macrisu]

Now the car is 100%.
Tomorrow I'll try again:

1. Start evcc
2. Login Eqc
3. Connect the car (eqc)

Send the logs if it's not recognised.

[Macrisu]

I’m in holiday, so no logs, but now my dad has a Renault Zoe and I’ve configuelred the car into evcc.
My eqc and Tesla are not connected and sleeping…

I think the problem is Tesla in DEEP sleep.
I get 408 error on SoC request.

If my dad connects the Zoe, it is seen as guest car.
If I hit Login EQC in the web interface, instantly Zoe is recognized; SoC updated.

I think the problem is Tesla in DEEP sleep.

I still don't unterstand the problem (have a Tesla myself). When you connect the Tesla it will not be in deep sleep and can be detected.

Or are you saying that having an inactive Tesla (which 408 error) in the config will prevent the other care from passing detection? If so, logs would help, please limit logs to the cars and remove modbus/ cache/ influx etc.

Cars:

• Tesla Model Y LR 2022
• Mercedes EQC 2021
• Renault Zoe

Charger: Go-E v3

Problem:

If I configure ONLY Mercedes in the evcc.yaml, all works, the car is recognised, SoC is working, charge is starting in PV mode.

If I add Tesla to the configuration,
Mercedes is not recognised anymore (guest), but Tesla is recognised.

The config evcc.yaml is here:
https://pastebin.com/qQA8iJWJ

Procedure:

1. Start EVCC 0.95 stable
2. Login EQC from the EVCC Interface
3. Plug the car into the charger

Result: EQC is seen as guest

Here is the log, but I do not see any errors.

./evcc --log trace

The log is pretty big so I've used pastebin, here is the link:

https://pastebin.com/9ns2bv4p

Other log, without Zoe (only Tesla and EQC), Influx or tarrifs

https://pastebin.com/mF0CB0AH

For Mercedes I only get:

[mercedes] TRACE 2022/07/03 14:11:55 callback request retrieved
[mercedes] TRACE 2022/07/03 14:11:55 sending login update...
[cache ] TRACE 2022/07/03 14:11:55 auth: {map[EQC:0xc000976440]}

P.S. Can I run another command than ./evcc --log trace ?

====
L.E.
If I put:

 vehicles: 
  #- MY
  - eqc1
  mode: pv

EQC is recognised immediately!

I've done the same thing, but with EQC and Zoe

 vehicles: #plural
  #- MY
  - eqc1
  - zoe
  mode: pv

Same result -> EQC is guest!

So, the problem is not Tesla/Zoe specific, the problem is when you have another car other than EQC!

This is the interface

This problem is ONLY when more than 1 vehicle is configured on the loading point (now EQC and Tesla)

[andig]

Can you please show the matching logfile? Does the logfile show that the vehicle is detected?

The answer is- once you start looking in the right place- obvious:

[lp-1  ] INFO 2022/07/05 18:11:37     vehicle 1: range ✓ finish ✗ status ✗ climate ✗ wakeup ✗
[lp-1  ] INFO 2022/07/05 18:11:37     vehicle 2: range ✓ finish ✓ status ✓ climate ✗ wakeup ✗

vehicle 1 does not deliver state and is hence not detectable!

[andig]

Follow-up in #3778

[andig]

If I remove Tesla ( -MY), all works!

Right- because with single vehicle only there isn‘t anything to detect…

[Macrisu]

Right!
So maybe it will be possible in the future to manually select the car :)

[Macrisu]

I've asked MB developers for API help, but they ask for details I cannot provide.
Can I forward the discussion to an email address?
