Made my Dumb 433Mhz roof FAN a bit smarter

Configuration
,
1

After watching @DrZzs

and doing it I could tasmota to lean the rf codes It has 4 speeds

high med low off

so I created a script for each one and MQTT sensor which keep track of the Speed

the two Sensor

- platform: mqtt
  name: "Lounge Fan Status"
  state_topic: "home/lounge-fan"

- platform: mqtt
  name: "Lounge Fan cmnd"
  state_topic: "home/lounge/fan/cmnd/FanSpeed"

now the Scripts


lounge_fan_3:
  alias: lounge fan Speed 3
  sequence:
    - service: mqtt.publish
      data:
        topic: "cmnd/RF_Bridge_raw/Backlog"
        payload: "RFRAW AA B0 1E 03 08 017C 02E4 2620 28090909181818180909090909090909180909090909 55 RFRAW 0"
    - service: mqtt.publish
      data:
        topic: "home/lounge-fan"
        payload: "3"
    - service: mqtt.publish
      data:
        topic: "home/lounge/fan/cmnd/FanSpeed"
        payload: "on"
  mode: single

lounge_fan_2:
  alias: lounge fan Speed 2
  sequence:
    - service: mqtt.publish
      data:
        topic: "cmnd/RF_Bridge_raw/Backlog"
        payload: "RFRAW AA B0 1E 03 08 0172 02E4 2620 28090909181818180909090909090918090909090918 55 RFRAW 0"
    - service: mqtt.publish
      data:
        topic: "home/lounge-fan"
        payload: "2"
    - service: mqtt.publish
      data:
        topic: "home/lounge/fan/cmnd/FanSpeed"
        payload: "on"
  mode: single

lounge_fan_1:
  alias: lounge fan Speed 1
  sequence:
    - service: mqtt.publish
      data:
        topic: "cmnd/RF_Bridge_raw/Backlog"
        payload: "RFRAW AA B0 1E 03 08 0172 02E4 2620 28090909181818180909090909090918180909091809 55 RFRAW 0"
    - service: mqtt.publish
      data:
        topic: "home/lounge-fan"
        payload: "1"
    - service: mqtt.publish
      data:
        topic: "home/lounge/fan/cmnd/FanSpeed"
        payload: "on"
  mode: single

lounge_fan_0:
  alias: lounge fan Speed 0
  sequence:
    - service: mqtt.publish
      data:
        topic: "cmnd/RF_Bridge_raw/Backlog"
        payload: "RFRAW AA B0 1E 03 08 017C 02E4 2620 28090909181818180909090909090909090918181818 55 RFRAW 0"
    - service: mqtt.publish
      data:
        topic: "home/lounge-fan"
        payload: "0"
    - service: mqtt.publish
      data:
        topic: "home/lounge/fan/cmnd/FanSpeed"
        payload: "off"
  mode: single

NOTE the script name and the payload of the MQTT

now the fan controler bit

- platform: mqtt
  name: "Lounge Fan"
  state_topic: "home/lounge/fan/cmnd/FanSpeed"
  command_topic: "home/lounge/fan/cmnd/FanSpeed"
  speed_state_topic: "home/lounge-fan"
  speed_command_topic: "home/lounge-fan"
  payload_on: "on"
  payload_off: "off"
  payload_low_speed: "1"
  payload_medium_speed: "2"
  payload_high_speed: "3"
  speeds:
    - low
    - medium
    - high

now the bit that join them

I want the right script to run when I select the speed

so could used the new choose option (still getting head around it)

- id: b12c44a8-d707-4892-9f75-c84c6927dab4
  alias: Lounge Fan Control
  initial_state: true
  trigger:
    - entity_id: sensor.lounge_fan_status
      platform: state
  action:
  - data_template:
      entity_id: script.lounge_fan_{{ trigger.to_state.state }}
    service: script.turn_on

now the tidy ups

- id: c9fe33f8-07a1-4bf3-9bd5-2fd144d4dcd6
  alias: Lounge Fan Status right
  trigger:
  - entity_id: sensor.lounge_fan_cmnd
    platform: state
    to: 'off'    
  action:
    - service: mqtt.publish
      data:
        topic: "home/lounge-fan"
        payload: 0

as I have all the right bits to make a switch so

  - platform: template
    switches:
      lounge_fan: 
        icon_template: mdi:fan
        friendly_name: Lounge Fan
        value_template: '{{ is_state("sensor.lounge_fan_cmnd", "on") }}'
        turn_on:
          service: script.turn_on
          data:
            entity_id: script.lounge_fan_1
        turn_off:
          service: script.turn_on
          data:
            entity_id: script.lounge_fan_0

putting all together

here the code

cards:
  - cards:
      - entity: climate.lounge_fan
        name: Lounge Fan
        type: 'custom:simple-thermostat'
        step_layout: row
        control:
          _headings: false
    type: horizontal-stack
  - cards: null
    entities:
      - entity: fan.lounge_fan
        type: 'custom:fan-control-entity-row'
        name: Fan
      - entity: switch.lounge_fan
    type: entities
  - cards:
      - align_state: center
        entities:
          - color: '#11A579'
            entity: sensor.bt_lounge_temperature
            index: 0
            name: Lounge
        type: 'custom:mini-graph-card'
    type: horizontal-stack
type: 'custom:vertical-stack-in-card'

cant take credit for the lovelace found that in here.

Make Smarter

what about working out the difference between the room temp and the climate setpoint

do some maths

    lounge_factor: 
      friendly_name: Lounge Factor
      value_template: >-
        {%set temp_indoor = states.sensor.bt_lounge_temperature.state | float %}
        {%set temp_fan = state_attr("climate.lounge_fan","temperature") %}
        {%set  factor = (temp_indoor - temp_fan)|int %}
        {{factor}}

now I get a Number

add a Input_boolean

  lounge_auto:
    name: Lounge Auto
    initial: off

so other automation

- id: 4d586798-4280-49e7-afc0-0e675bb30dbd
  alias: Auto Lounge Fan Control
  initial_state: true
  trigger:
  - platform: state
    entity_id: sensor.lounge_factor
  condition:
    condition: and
    conditions:
    - condition: state
      entity_id: input_boolean.lounge_auto
      state: 'on'
    - condition: numeric_state
      entity_id: sensor.lounge_factor
      above: 0
  action:
  - data_template:
      entity_id: script.lounge_fan_{{ trigger.to_state.state }}
    service: script.turn_on

so now if as the room get warmer the fan speed should increase and decrease and it get cooler

I’m currently trying to implement this into my HA and I’m stuck at this point, I have added it into my config.yaml
