Configure SMA Solar custom sensor setup

Hi y’all,

i’m a bit lost here and i hope someone could enlighten me…

I do have an SMA Solar Inverter and have enabled the SMA integration of HA according to this: homeassistant//integrations/sma/

Everything worls as expected.
Now i want to add a custom sensor as described in the manual above, but i don’t know, where to put the custom: thing.
If i put it like this

sensor:
  - platform: sma
    host: IP_ADDRESS_OF_DEVICE
    ssl: true
    verify_ssl: false
    password: YOUR_SMA_PASSWORD
    sensors:
      - current_consumption
      - total_consumption
      - pv_power
      - total_yield
    custom:
      yesterday_consumption:
        key: "6400_00543A01"
        unit: kWh
        factor: 1000

it gives me an error upon config-check like this:

Invalid config for [sensor.sma]: expected dictionary for dictionary value @ data['custom']. Got [OrderedDict([('total_consumption', OrderedDict([('key', '6400_00462500'), ('unit', 'kWh'), ('factor', 1000)]))])]. (See ?, line ?). 
                        

am i overlooking something here or am i just to stup… to read the manual?

Thanks

Ok, my bad.
Just was to stupid to see the double quotes at the key value.

key: "6400_00543A01"

Changed it to simple quotes and it’s up and running.
