Multiple entities, single rest endpoint to SET values

Configuration
1

Hi!! :smiley:

I have an AC unit that has two REST endpoints:

1- get_state: returns a json of all its values (temperature, mode, fan, etc)
2- set_state: send a JSON with temperature, mode, fan, etc. values to set the ac state.

For the sake of simplicity, I’ll include only mode and fanspeed here. Here’s the essential part of my configuration:

rest_command:
  silhouette_set_ac:
    url: >-
      {% set mode_mapper =  {
        'Auto': 0,
        'Refroidissement': 1,
        'Déshumidificateur': 3,
        'Ventilateur': 4 } %}
      {% set mode = mode_mapper[states('select.silhouette_state_mode')] %}
      {% set fanspeed_mapper =  {
        'Auto': 0,
        'Doux': 1,
        'Moyen': 3,
        'Fort': 4 } %}
      {% set fanspeed = fanspeed_mapper[ states('select.silhouette_state_fanspeed')] %}
      http://192.168.10.80/set_ac?mode={{ mode }}&fanspeed={{ fanspeed }}

rest:
  - resource: http://192.168.10.80/get_ac
    scan_interval: 5
    verify_ssl: false
    sensor:
      - name: silhouette_state_mode
        unique_id: silhouette_state_mode
        value_template: >-
          {% set mapper =  {
            0: 'Auto',
            1: 'Refroidissement',
            3: 'Déshumidificateur',
            4: 'Ventilateur' } %}
          {% set state =  value_json.mode %}
          {{ mapper[state] if state in mapper else 'Inconnu' }}
      - name: silhouette_state_fanspeed
        unique_id: silhouette_state_fanspeed
        value_template: >-
          {% set mapper =  {
              0: 'Auto',
              1: 'Doux',
              3: 'Moyen',
              4: 'Fort' } %}
          {% set state =  value_json.fanspeed %}
          {{ mapper[state] if state in mapper else 'Inconnu' }}

template:
  select:
    - name: silhouette_state_mode
      unique_id: silhouette_state_mode
      state: "{{ states('sensor.silhouette_state_mode') }}"
      options:  "{{['Auto', 'Refroidissement', 'Déshumidificateur', 'Ventilateur']}}"
      select_option:
        - service: rest_command.silhouette_set_ac
    - name: silhouette_state_fanspeed
      unique_id: silhouette_state_fanspeed
      state: "{{ states('sensor.silhouette_state_fanspeed') }}"
      options:  "{{['Auto', 'Doux', 'Moyen', 'Fort']}}"
      select_option:
        - service: rest_command.silhouette_set_ac

Let’s pretend that currently, both selects are set to ‘Auto’. The selects update their values every 5 seconds. This is fine.

Now for example, when select.silhouette_state_mode changes to something else, rest_command.silhouette_set_ac gets called, BUT in there states('select.silhouette_state_mode') is STILL ‘Auto’!

So I tried to pass the selected value like this for both selects:

template:
  select:
    - name: silhouette_state_mode
      unique_id: silhouette_state_mode
      state: "{{ states('sensor.silhouette_state_mode') }}"
      options:  "{{['Auto', 'Refroidissement', 'Déshumidificateur', 'Ventilateur']}}"
      select_option:
        - service: rest_command.silhouette_set_ac
          data:
            mode: "{{ option }}"
    - name: silhouette_state_fanspeed
      unique_id: silhouette_state_fanspeed
      state: "{{ states('sensor.silhouette_state_fanspeed') }}"
      options:  "{{['Auto', 'Doux', 'Moyen', 'Fort']}}"
      select_option:
        - service: rest_command.silhouette_set_ac
          data:
            fanspeed: "{{ option }}"

And in the rest_command check for those variables:

  silhouette_set_ac:
    url: >-
      {% set power = is_state('switch.silhouette_state_power', 'on') | abs %}
      {% set mode_mapper =  {
        'Auto': 0,
        'Refroidissement': 1,
        'Déshumidificateur': 3,
        'Ventilateur': 4 } %}
      {% set mode = mode_mapper[mode if mode is defined else states('select.silhouette_state_mode')] %}
      {% set fanspeed_mapper =  {
        'Auto': 0,
        'Doux': 1,
        'Moyen': 3,
        'Fort': 4 } %}
      {% set fanspeed = fanspeed_mapper[fanspeed if fanspeed is defined else states('select.silhouette_state_fanspeed')] %}
      http://192.168.10.80/set_ac?power={{ power }}&mode={{ mode }}&fanspeed={{ fanspeed }}

With this, if I change the fan to ‘Doux’, the rest_command uses ‘Doux’ mode and ‘Auto’ fan. But then if I change the mode to ‘Ventilateur’, the rest_command sends ‘Auto’ fan and ‘Ventilateur’ mode.

So apparently, states() always returns the state from its state template, NOT the selected value.

Now I could do a lot of things like using input_selects and mapping them to get_state and set_state apis with scripts and automations but wow is this getting out of hand! If there was a single REST endpoint for each value to set, I’d be done already but that’s not the case.

What’s the cleanest and simplest way to send the currently SELECTED values of multiple entities to a single rest api endpoint?
