I dont think water heater generally have am on state. Its all weird heatpump, eco, ... states.

[adamweiss]

I was going based off the action_types in strings.json:

{
  "device_automation": {
    "action_type": {
      "turn_on": "Turn on {entity_name}",
      "turn_off": "Turn off {entity_name}"
    },
    "trigger_type": {
      "turned_on": "{entity_name} turned on",
      "turned_off": "{entity_name} turned off"
    }
  }

But I can update this with the states in water_heater/__init__.py:

STATE_ECO = "eco"
STATE_ELECTRIC = "electric"
STATE_PERFORMANCE = "performance"
STATE_HIGH_DEMAND = "high_demand"
STATE_HEAT_PUMP = "heat_pump"
STATE_GAS = "gas"

[elupus]

I think you have to. Or trigger on OFF and NOT OFF
