Unable to use input_select in Automation or dev tools

Configuration
1

I have an input select in ESPHome that Im trying to change in an automation.
It fails so I tried it in dev tools and it fails there also

select:
  - platform: "tuya"
    tuya_id: "house"
    name: "ESPH House Power Select"
    enum_datapoint: 4
    options:
      0: P1-High
      1: P2-Med High
      2: P3-Med Low
      3: P4-Low

I know it works because I change it in the Lovelace card and I get log entries of it changing and it changes on the device:

In dev tools I try and call this service, but it does nothing.

service: input_select.select_option
data:
  option: P1-High   # I've also tried 0,1,2 and 3 Thinking it's the index that's needed?
target:
  entity_id: select.esph_house_power_select

What am I doing wrong? It has to be something really basic I’m doing wrong.
