The obsolete syntax platform: templatefor sensoris being removed. Please migrate crypto_totalto the modern template syntax.

Remove the existing template definition.
Add new template definition:

template:
- sensor:
  - unit_of_measurement: "{{ expand(integration_entities('cryptoinfo'))\n    | map(attribute='attributes.unit_of_measurement')\n
      \   | list | default(['$'], true)\n    | first }}\n"
    default_entity_id: sensor.crypto_total
    name: Total my crypto
    state: "{{ integration_entities('cryptoinfo')\n    | map('states')\n    | map('float',
      0)\n    | sum | round(2) }}"

Restart Home Assistant or reload the model entities.
