Cannot add integration more than once

[bslefevre]

After updating to the latest version which fixes the description bug (introduced by the Wallbox API) I cannot use both accounts on 1 Charger anymore.

The entities where acting funny (not working/gone) after updating so I've removed both of the integrations.

Now I'm re-adding the integration and it works the first time, but when I'm trying to add the second account with the same serialnumber (which worked fine before) i says:

I'm using 2 accounts to unlock the Wallbox with the corresponding EV. My car needs to be declared to my employer and my wife's car not

Am I doing something wrong or is this an issue introduced since the latest version?

Additional info:

• HASS version: core-2022.4.1
• Raspi 4
• Python v3.9.10

Hi, yes this is by design, also the way that HomeAssistant integrations are supposed to work (define uniqueness of a device). What is exactly your usecase here for adding it two times?

I'm using 2 accounts to unlock the Wallbox with the corresponding EV. My car needs to be declared to my employer and my wife's car not

Is there a way to work around this feature? It worked like a dream before

And the wallbox uses the unlock account to allocate the cost differently? I'm trying to determine if it is some thing the integration should be supporting. Dont have a Quick fix btw

Yes, well not the costs but for the reporting afterwards
When you unlock the Wallbox with account A you can export all the charges being activated by account A.
This comes in really handy when you need to declare all the costs from a specific account but not another account
