Dyson - set fan speed in lovelace

Configuration
1

Dear community,
Is it possible to have a slider or nice visual element on Lovelace UI to control my Dyson fan speed? It goes from 1 to 10 then auto and night modes.
Thanks!

I don’t use a dyson fan, but I would do something like this:

Create an input_number to control the speed the fan:

input_number:
  fan_speed_control:
    name: "Fan Speed Control"
    initial: 1
    min: 1
    max: 10
    step: 1

Create an automation that changes the fan speed every time the input_number changes.

- id: '4549823579843'
  alias: 'Change fan speed on change of input_number'
  trigger:
    platform: state
    entity_id: finput_number.fan_speed_control
  action:
    service: fan.set_speed
    entity_id: fan.dyson_fan
    data_template:
      dyson_speed: "{{ trigger.to_state.state | int }}"

Use the input_number in your lovelace view.

Thanks for this, I was looking for this as well.

One minor correction - you need to call the dyson.set_speed service rather than the fan.set_speed service. The latter only accepts the attribute “speed” with the values “low, medium & high”.

Can anyone help me with this? I tried a few things but none of them seem to get this up and running. This is my code in automations.yaml and a screenshot of the GUI

- id: '4549823579843'
  alias: 'Change fan speed on change of input_number'
  trigger:
    platform: state
    entity_id: input_number.fan_speed_control
  action:
    service: dyson.set_speed
    entity_id: fan.schlafzimmer
    data_template:
      dyson_speed: "{{ trigger.to_state.state | int }}"

This is what my helper looks like:

I only changed it to my values. This is what I found in the logs:

Can anyone help me with this? Thanks in advance!

The first error is probably because you tried to manually trigger the automation and it therfore couldn’t find a trigger.
Does setting fan speed manually through Developer Tools -> Services work?
Can you please try putting the entity_id part in the action section into the data_template part like this:

action:
  service: dyson.set_speed
  data_template:
    entity_id: fan.schlafzimmer
    dyson_speed: "{{ trigger.to_state.state | int }}"

Thats it! :smiley: Yes under developer tools everything was working fine. When I put the entity_id under data_template its working as it should.

This whole YAML thing still drives me crazy as I´ve never worked with it before :grinning:

Thanks a lot for your help!

Normally it shouldn’t make a difference wheter you put it inside the data part or not, but there are some exceptions (like your example) where it needs to be inside the data part, I don’t know all the details and to be honest I don’t care because I don’t create my automations inside Home Assistant :slight_smile:
