Fan templating broken

[hubertgruber]

In Home Assistant 2022.2, the fan templating is broken, as there is now a requirement for a percentage. See https://developers.home-assistant.io/docs/core/entity/fan/#deprecated-properties.

I'll have a look at how to rewrite it to a better and more reproducable thing

Hi @hubertgruber - I recently moved everything and didn't realise not using the templating broke that way. I tried rewriting it already but there is a snag. It seems esphome / fan is not able to 'take' speed settings from something external.

I'll leave my rewrite of the esp yaml below - if you are only using the fan-component (i.e. skip setting high for 10/20/30 minutes etc.) and not have the intent to 'read' whatever the physical switches are sending you can get away with it.

The below code is based off having the custom switches as already included in the original version.

fan:
  - platform: speed
    speed_count: 3
    output: mech_vent
    name: "Mechanische ventilatie"
    restore_mode: NO_RESTORE
    on_turn_on:
    - logger.log: "Fan Turned On, setting to 10min!"
    - switch.turn_on: fansendt1

    on_turn_off:
    - logger.log: "Fan Turned Off, setting to low speed!"
    - switch.turn_on: fansendlow

output:
  - platform: template
    id: mech_vent
    type: float
    write_action:
      - if:
          condition:
            lambda: return ((state == 0));
          then:
            # action for off
            - logger.log: "Fan set to low speed"
            - switch.turn_on: fansendlow
      - if:
          condition:
            lambda: return ((state > 0) && (state < .34));
          then:
            # action for low
            - logger.log: "Fan set to low speed"
            - switch.turn_on: fansendlow
      - if:
          condition:
            lambda: return ((state > .34) && (state < .67));
          then:
            # action for medium
            - logger.log: "Fan set to medium speed"
            - switch.turn_on: fansendmedium

      - if:
          condition:
            lambda: return ((state == 1));
          then:
            # action for high
            - logger.log: "Fan set to high speed"
            - switch.turn_on: fansendhigh

If it doesn't (re)build for you on homeassistant itself (using the esphome addon) - it works for me using this on the top

esphome:
  name: {yournamehere}
  platform: ESP8266
  board: d1_mini_lite
  libraries:
    - SPI
    - https://github.com/CoMPaTech/esphome_itho.git
    - Ticker
  includes:
    - ITHO/fancontrol.h

Which - in less detail - is also what https://github.com/CoMPaTech/esphome_c1101_alt already does - so you might want to give that a spin as well

Thank you very much! I got it working on my system too! I had to remove the restore_mode and add id's for the previously made custom switches, but it works like a charm again now! Here's my code for completeness:

esphome:
  name: esp_atmega_itho_1
  platform: ESP8266
  board: nodemcuv2
  includes: 
    - c1101.h
    - ITHO/fancontrol.h
  libraries: 
    - SPI
    - https://github.com/CoMPaTech/esphome_itho.git
    - Ticker

#### End fix for HA OS 2022.2

[hubertgruber]

Closing because fan now works from HA OS 2022.2 onward with new code.
