Variable Speed Pumps

Variable Speed Pumps

Unfortunately Home Assistant doesn't have a "pump" entity with variable speed capabilities, so we have leveraged the "switch" entity for all pumps and added a custom service which will allow you to control your variable speed pumps.

Recommended Helper

The pump speed for variable pumps is exposed as a sensor which you can track. I prefer to also have a control to use for the pump as a slider in my UI, so I found it easier to create a helper for this purpose. Go to the Helpers section of the setup in Home Assistant and create a new helper with the following characteristics:

• Name: Pool Pump Speed
• Icon: mdi:gauge
• Minimum Value: The lowest % setting allowed on your pump - in my case this was 35
• Maximum Value: 100
• Display Mode: Slider
• Step Size: 1
• Unit of Measurement: %
• Entity ID: input_number.pool_pump_speed

You will then need two services to allow your helper to control the pump and to keep it synced with speed changes that happen outside of the slider:

Automation 1: Pool - Set Pump Speed

alias: Pool - Set Pump Speed
description: ''
trigger:
  - entity_id: input_number.pool_pump_speed
    platform: state
condition:
  - condition: state
    entity_id: switch.POOL_PUMP_ENTITY
    state: 'on'
action:
  - data_template:
      entity_id: switch.POOL_PUMP_ENTITY
      speed: '{{ states.input_number.pool_pump_speed.state | int }}'
    service: omnilogic.set_pump_speed
mode: single

Automation 2: Pool - Update Pump Speed Slider

alias: Pool - Update Pump Speed Slider
description: ''
trigger:
  - entity_id: sensor.POOL_PUMP_ENTITY
    platform: state
  - event: start
    platform: homeassistant
condition:
  - condition: state
    entity_id: switch.POOL_PUMP_ENTITY
    state: 'on'
action:
  - data_template:
      value: '{{ (states.sensor.POOL_PUMP_SPEED_ENTITY.state | float) }}'
    entity_id: input_number.pool_pump_speed
    service: input_number.set_value
mode: single
max: 20

Recommended Scripts - Speed Quick Sets for Buttons

To make it easy to set your pump speed without the slider, I have created three 'quick settings' for the pump speed that I expose through buttons on the UI. In my case I used 35%, 55%, and 85% as my 'low', 'medium', and 'high' settings, but you can use whatever works best for you and your pool. These are created as scripts that are identical other than the speed:

Script: Pool Pump - X%

Example for 35% script:

alias: Pool Pump - 35%
mode: single
sequence:
  - data:
      speed: 35
    entity_id: switch.POOL_PUMP_ENTITY
    service: omnilogic.set_pump_speed

The scripts can then be used easily as buttons on the UI, or in automations for scheduling pump speeds (for example set to 'low' from 7am-7pm, 'high' from 7pm-7am).
