Help with Water Consumption

I have a flow meter that measures daily pool water consumption. I am trying toad this to the energy Dashboard and I get the following error

Thanks for the help in advance

Invalid config for ‘utility_meter’ at utility_meter.yaml, line 98: Entity ID water_usage_pool_daily is an invalid entity ID for dictionary value ‘utility_meter->daily_water_consumed_gallons->source’, got ‘water_usage_pool_daily’

utility_meter.yaml

## WATER POOL USAGE###
water_usage_pool_daily:
  source: sensor.total_pool_filling
  name: "Water Usage For Pool Daily"
  cycle: daily
  unique_id: total_pool_filling_daily
  
water_usage_pool_hourly:
  source: sensor.total_pool_filling
  name: "Water Usage For Pool Hourly"
  cycle: hourly
  unique_id: total_pool_filling_hourly

daily_water_consumed_gallons:
  source: water_usage_pool_daily
  cycle: daily
  name: "Daily Water (Gallons)"
  unique_id: utility_meter_daily_water_gal  

You are missing the domain for the source entity id.

Should be:

daily_water_consumed_gallons:
  source: sensor.water_usage_pool_daily

Though I’m not sure why you are doing this. Unless you want the duplicate daily sensor so you can change the unit of one of them in the frontend?
