ESPHome-Smart-Scale

I have a problem with an card to display in homeassistant, i hope somebody can help.

I have installed: ESPHome-Smart-Scale
from the site https://github.com/markusressel/ESPHome-Smart-Scale

It looks like the sensor is working wel.

The i installed with hacks the multiple-entity-row add-on
which is necceserry for the card.

then installed the code:

title: Devices
type: vertical-stack
cards:

  • type: entities
    show_header_toggle: false
    state_color: false
    entities:
    • entities:
      • entity: switch.smart_scale_continuous_tare_enabled
        name: Auto Tare
        toggle: true
      • entity: button.smart_scale_manual_tare_action
        name: Manual Tare
        type: Button
        icon: mdi:scale-balance
        tap_action:
        action: call-service
        service: button.press
        service_data:
        entity_id: button.smart_scale_manual_tare_action
      • entity: sensor.smart_scale_hx711_value
        name: Current
        entity: input_number.weight_markus
        name: Smart Scale
        icon: mdi:scale-bathroom
        secondary_info: last-changed
        state_header: Markus
        type: custom:multiple-entity-row

but the card is not working, i get the message
“Entity is not available: input_number.weight_markus”

Does somebody know what is wrong?
