Error on card - only when car is not connected

[AMajland]

I have an easee home configured with the card filled with full template from the main instruction page.

When a car is connected by cable I have the stop, resume and override schedule icons at the bottom of the card.

But when the car is not connected i get an error instead of these 3 icons.

I'm completely new to home assistant - still finding my way around like an elephant in a porcelain store :-)

Hi,

It seems to be looking for something that doesn't exist (hence the null). It could be something in the configuration of the card (either a bugin the template, or something that possibly added up during back and forth). Could you post the complete card config?

[AMajland]

I've just verified that my my config is identical to the full advanced configuration as shown on https://github.com/tmjo/charger-card (Did a diff of my config vs the online one)

I've also verified that all the entity_id are available and active.

The only thing that comes to my mind is that the CHARGERID and CHARGERNAME is the same for me. But have not tried to look below the surface .... (yet)

[tmjo]

Better if you post the config. Anyway, you can try to open DevTools in Chrome (or similar) with CTRL+SHIFT+I and look for some more detailed debugging info in the messages there.

Also, you could try replacing

disconnected:
      - {}

with

disconnected:
      - service: easee.stop
        service_data:
          charger_id: CHARGERID
        text: stop
        icon: hass:stop

in the toolbar_left section as a test just to see what happens.

I'm not sure if the serial number can be abused in some way, but here is my code with it removed. I'll try you suggestion tonight - Slow charging all day with solar power (Nordpool DK1 is almost 0 most of the day so tries to use most of my solar power instead of selling it for nothing)

Clicking on it gives "charger-card.js?hacstag=308752409011:7147 Trying to call an empty service - please check your card configuration."

And as you noticed

 disconnected:
      - {}

is in fact empty.

And replacing it with the stop bottom got rid of the error (the stop bottom does nothing meaingfull when not connected but at least the card look nicer :-) )

[tmjo]

Hmmm, thats's kindof good. I see that if I simulate 'disconnected' as status I also get a icon '?' showing null. Do you get the error only when clicking the button, or all the time?

Seems like deleting the section

    default:
      - {}
    disconnected:
      - {}

solves it, then you get an empty toolbar. Or you could add something that makes sense while disconnected (although I couldn't really find anything).

[tmjo]

@AMajland; sorry for the delay, but if you don't mind, please check latest version just released to see if this bug is solved.

[AMajland]

Thankyou for the update. The stop button is now shown when the car is disconnected. Pressing the stop button gives the error shown here. - But since it is disconnected there is nothing to stop :-)

But got this error in the settings after pressing the stop button:

[tmjo]

Well, yes, two things: Stop doesn't work when car is disconnected, and the second error message is a deprecation of some services that has been changed in the Easee integration (will be added to card soon). But the original problem was that

    default:
      - {}
    disconnected:
      - {}

gave errors, right? And the workaround was to add a button (hence the stop-button).

[tmjo]

Closing this as I believe it has been solved. Please re-open if this is not the case.
