Help with template fan direction not working

xbmcnut · October 19, 2019, 9:44pm

I’ve been building my Broadlink fans for weeks and everything is working great except the direction command. It seems I may need a data_template in my script as the template fan direction command is not accepting my basic script. Can anyone help me build that?

        speed_template: "{{ states('input_select.master_fan_set_speed') }}"
        direction_template: "{{ states('input_select.master_fan_direction') }}"
        turn_on:
          service: script.bedroom_fan_on
        turn_off:
          service: script.bedroom_fan_off
        set_speed:
          service: script.master_fan_set_speed
          data_template:
            speed: "{{ speed }}"
        set_direction:
          service: script.turn_on
          entity_id: script.master_fan_reverse

  master_fan_reverse:
    alias: Master Fan Reverse
    sequence:
      - service: broadlink.send
        data:
          host: 'ipofbroadlink'
          packet: 'broadlinkcodetosend'

If I run the script on its own, the fan reverses but if I use the input_select with forward/reverse, it does not.

This is the section from the Template Fan I’m unsure about.

        set_direction:
          service: script.fan_direction
          data_template:
            direction: "{{ direction }}"

UPDATE: I’ve copied the speed template in an attempt to get the direction working but using the code below, it still does not work. Anyone see why? As before, the individual forward/reverse scripts work on their own.

        direction_template: "{{ states('input_select.master_fan_direction') }}"
        turn_on:
          service: script.bedroom_fan_on
        turn_off:
          service: script.bedroom_fan_off
        set_speed:
          service: script.master_fan_set_speed
          data_template:
            speed: "{{ speed }}"
        set_direction:
          service: script.master_fan_direction
          data_template:
            direction: "{{ direction }}"

  master_fan_direction:
    name: Master Fan Direction
    options:
      - 'forward'
      - 'reverse'

  master_fan_reverse:
    alias: Master Fan Reverse
    sequence:
      - service: broadlink.send
        data:
          host: 'broadlinkip'
          packet: 'broadlinkcodetosend'

  master_fan_forward:
    alias: Master Fan Forward
    sequence:
      - service: broadlink.send
        data:
          host: 'broadlinkip'
          packet: 'broadlinkcodetosend'

  master_fan_direction:
    alias: Master Fan Direction
    sequence:
    - service: input_select.select_option
      data_template:
        entity_id: input_select.master_fan_direction
        option: '{{direction}}'
    - service: script.turn_on
      data_template:
        entity_id: script.master_fan_{{ direction }}

Anyone got any ideas?

123 · October 30, 2019, 12:29pm

To change the fan’s direction, is it one IR code (it toggles the direction) or are there two IR codes (one for each direction)?

For the configuration of set_direction, instead of the service calling a script, have you tried calling broadlink.send? In other words, eliminate the script and place its service call within the Template Fan’s set_direction.

petro · October 30, 2019, 12:44pm

That’s what I’d do. Template the package field with

data_template:
  host: 'broadlinkip'
  packet: >
    {% if direction == 'forward' %}
      forward packet number
    {% else %}
      Backward packet number
    {% endif %}

I’m on mobile and don’t have access to the correct quote style, so you’ll need to change to the correct single quote type

Thanks for your help @petro and @123. Much appreciated. I tweaked my code below but it’s still not working. Did I do it correctly?

fan:
  - platform: template
    fans:
      template_bedroom_fan:
        friendly_name: "Master Bedroom Fan"
        value_template: "{% if states('sensor.bedroom_fan_shelly_power') | float > 3 %}on{% else %}off{% endif %}"
        speed_template: "{{ states('input_select.master_fan_set_speed') }}"
        direction_template: "{{ states('input_select.master_fan_set_direction') }}"
        turn_on:
          service: script.bedroom_fan_on
        turn_off:
          service: script.bedroom_fan_off
        set_speed:
          service: script.master_fan_set_speed
          data_template:
            speed: "{{ speed }}"
        set_direction:
          service: broadlink.send
          data_template:
            host: 'hostip'
            packet: >
              {% if direction == 'forward' %}
                'broadlinkcode.samefor.forwardandreverse='
              {% else %}
                'broadlinkcode.samefor.forwardandreverse='
              {% endif %}

        speeds:
          # - 'Select Speed'
          - '1' ## 4.27~5.07 watts ##
          - '2' ## 6.33~6.67 watts ##
          - '3' ## 9.46~9.93 watts ##

input_select:
  master_fan_set_speed:
    name: Master Bedroom Speed
    options:
      # - 'Select Speed'
      - '1'
      - '2'
      - '3'
    # initial: 'Select Speed'
    icon: mdi:fan

  master_fan_set_direction:
    name: Master Fan Direction
    options:
      - 'forward'
      - 'reverse'

This works in the template editor but does not change the fan direction.

        set_direction:
          service: broadlink.send
          data_template:
            host: '10.0.1.220'
            packet: >
              {% if states.input_select.master_fan_set_direction.state == 'forward' %}
                '123456789AAAAAAAAAAAAAAAA='
              {% else %}
                '123456789AAAAAAAAAAAAAAAA='
              {% endif %}

xbmcnut · November 1, 2019, 3:15am

It’s a toggle (one code).

xbmcnut · November 1, 2019, 3:34am

Also tried this just for fun, does not work either.

        set_direction:
          service: broadlink.send
          data_template:
            packet: >
              {% if is_state('input_select.master_fan_set_direction', 'forward') %}
                "123456789AAAAAAAAAAAAAAAA="
              {% elif is_state('input_select.master_fan_set_direction', 'reverse') %}
                "123456789AAAAAAAAAAAAAAAA="
              {% endif %}
            host: 10.0.1.220

Yet, if I use the same data in the Dev > Services tab, it works.

123 · November 1, 2019, 3:53am

If one code is used to toggle the direction, why is your template checking the input_select’s direction? Forward or reverse, it sends the same code so I don’t see a need for a template.

        set_direction:
          service: broadlink.send
          data:
            host: '10.0.1.220'
            packet: '123456789AAAAAAAAAAAAAAAA='

Anyway, that’s just an observation and it probably isn’t responsible for the problem.

xbmcnut · November 1, 2019, 5:21am

Thanks and you’re correct, that did not work either. Might be a problem with the template fan integration? I’ve tidied up the code as you’ve suggested just in case.

123 · November 1, 2019, 6:01am

I just re-read your original post and saw what you said with fresh eyes. The input_select does not control the Template Fan’s direction.

The fan’s direction is controlled using the two buttons seen here in the lower left:

Screenshot%20from%202019-11-01%2001-52-08

Your fan’s configuration has this:

direction_template: "{{ states('input_select.master_fan_direction')

That’s not for controlling the fan, that’s for reporting feedback from the actual fan.

When you change the fan’s direction using one of the two buttons in the UI (seen above), set_direction runs and sends the Broadlink IR command to the actual fan. Then the Template Fan expects to receive the fan’s new direction via direction_template.

From the documentation:

direction_template
(template)(Optional)
Defines a template to get the direction of the fan. Valid value: ‘forward’/‘reverse’

It says get the direction of the fan, not set the direction of the fan.

xbmcnut · November 1, 2019, 6:08am

Ah ha! Now we’re getting somewhere. So if I have no feedback from the fan in regards to what direction it’s going, what do I put in the direction_template as I was just copying the speed one above it?

The docs are quite confusing but from what you’re saying, the direction_template creates the arrows does it? Based on your feedback, I’d say I have an issue with my speed template too as I’ve misinterpreted that function too (even though speed is working).

123 · November 1, 2019, 6:18am

If there’s no feedback from the fan then just fake it. Here’s what I suggest:

Create an input_boolean to represent the fake direction status. Let’s say that on means forward and `off means reverse.

Change the direction_template so that it uses the input_boolean.

direction_template: "{{ 'forward' if is_state('input_boolean.master_fan_direction', 'on') else 'reverse' }}"

In set_direction, add a second service call to toggle the state of the input_boolean.

        set_direction:
          - service: broadlink.send
            data:
              host: '10.0.1.220'
              packet: '123456789AAAAAAAAAAAAAAAA='
          - service: input_boolean.toggle
            entity_id: input_boolean.master_fan_direction

xbmcnut · November 1, 2019, 6:26am

Thank you, I’ll give that a try. So is my current input boolean valid?

  master_fan_set_direction:
    name: Master Fan Direction
    options:
      - 'forward'
      - 'reverse'

Never mind, I just remove the options.

xbmcnut · November 1, 2019, 9:13am

Success @123! Thank you. Been bugging me for 6 weeks. I used your exact code. I’ll put in a PR to see if we can have valid options for winter/summer as well as forward/reverse as that would increase the WAF!

The only thing I’d like to tidy up is the speed selection as currently it defaults to 1, but you have to select 2 or 3 to start the fan. I’d like to be able to select 1 as the first speed option. I know I can just turn it on when its on 1 but I’m a stickler for detail.

Here is my current speed set up which I complied from various forums posts.

speed_template: "{{ states('input_select.master_fan_set_speed') }}"

        set_speed:
          service: script.master_fan_set_speed
          data_template:
            speed: "{{ speed }}"

        speeds:
          # - 'Select Speed'
          - '1' ## 4.27~5.07 watts ##
          - '2' ## 6.33~6.67 watts ##
          - '3' ## 9.46~9.93 watts ##

input_select:
  master_fan_set_speed:
    name: Master Bedroom Speed
    options:
      # - 'Select Speed'
      - '1'
      - '2'
      - '3'
    # initial: 'Select Speed'
    icon: mdi:fan

script:
  bedroom_fan_on:
    alias: MasterFan (On)
    sequence:
      - service_template: >
          {% if is_state("input_select.master_fan_set_speed", "1") %}
            script.bedroom_fan_1
          {% elif is_state("input_select.master_fan_set_speed", "2") %}
            script.bedroom_fan_2
          {% elif is_state("input_select.master_fan_set_speed", "3") %}
            script.bedroom_fan_3
          {% endif %}

  master_fan_set_speed:
    alias: Master Fan Set Speed
    sequence:
    - service: input_select.select_option
      data_template:
        entity_id: input_select.master_fan_set_speed
        option: '{{speed}}'
    - service: script.turn_on
      data_template:
        entity_id: script.bedroom_fan_{{ speed }}

Got it all working perfectly! Thanks for your help @123 and @petro. Full code here.

Wondering if someone can assist with converting my template fan config over to the new percentage based system introduced in 201.3.x?

bdraco · March 12, 2021, 8:03am

These two posts might be enough to get you started.

I forked an updated your gist here. You might need to tweak master_fan_set_percentage a bit.
