Hi all,

I have this card:

  - type: map
    entities:
      - entity: sensor.gas_station_euro95_work_lowest_price_1
        name: LP 1
      - entity: sensor.gas_station_euro95_work_lowest_price_2
        name: LP 2
      - entity: sensor.gas_station_euro95_work_lowest_price_3
        name: LP 3
      - entity: sensor.gas_station_euro95_work_lowest_price_4
        name: LP 4
      - entity: sensor.gas_station_euro95_work_lowest_price_5
        name: LP 5
    geo_location_sources: []
    auto_fit: true

and want store this map into a file so I can send it with notify to my phone.
When im at my work I can check before drive back home if the prices are cheaper near my work or its better to drive home and go to gas station nearby home.
