How to use input_number in sensor value template?

1

Hey everybody,

my goal is to replace static number in value template with input_number, so that I could pass values to sensor from UI.

E.g. I have this template:

       value_template: >
         {%- set numberOfSequentialHours = 3 -%}
         {%- set lastHour = 23 -%}
         {%- set firstHour = 0 -%}

where numberOfSequentialHours is set to 3. I want it to be set to whatever input_number helper holds, i.e.:

       value_template: >
         {%- set numberOfSequentialHours2 = "{{ states('input_number.sequential_hours') | int }}" -%}
         {%- set lastHour2 = 23 -%}
         {%- set firstHour2 = 0 -%}

Can’t get it to work.

Everything you have there is correct. Try sharing the entire sensor config.

- platform: template
  sensors:
    cheapest_custom_hours_energy_tomorrow:
      unique_id: t24psb/nxp5qR+XqPdp8CtpJo6Wq5tJjvergdfLRxGg=
      device_class: timestamp
      friendly_name: Cheapest custom sequential electricity hours
      value_template: >
        {%- set numberOfSequentialHours = "{{ states('input_number.sequential_hours') | int }}" -%}
        {%- set lastHour = 23 -%}
        {%- set firstHour = 0 -%}

        {%- if state_attr('sensor.nordpool_kwh_lt_eur_3_10_021', 'tomorrow_valid') == true -%}
          {%- set ns = namespace(counter=0, list=[], cheapestHour=today_at("00:00") + timedelta( hours = (24)), cheapestPrice=999.00) -%}
          {%- for i in range(firstHour + numberOfSequentialHours, lastHour2+1) -%}
            {%- set ns.counter = 0.0 -%}
            {%- for j in range(i-numberOfSequentialHours22, i) -%}
              {%- set ns.counter = ns.counter + state_attr('sensor.nordpool_kwh_lt_eur_3_10_021', 'tomorrow')[j] -%}
            {%- endfor -%}
            {%- set ns.list = ns.list + [ns.counter] -%}
            {%- if ns.counter < ns.cheapestPrice -%}
              {%- set ns.cheapestPrice = ns.counter -%}
              {%- set ns.cheapestHour = today_at("00:00") + timedelta( hours = (24 + i - numberOfSequentialHours)) -%}
            {%- endif -%}
          {%- endfor -%}
          {{ ns.cheapestHour }}
          {%- set ns.cheapestPrice = ns.cheapestPrice / numberOfSequentialHours -%}
        {%- endif -%}

If I put any number instead of “{{ states(‘input_number.sequential_hours’) | int }}” - it works.

What does this return in the template editor?

{{ states('input_number.sequential_hours') | int }}

It returns plain 3.

Try this:

        {%- set numberOfSequentialHours = states('input_number.sequential_hours') | int  -%}

If I don’t put quotes, I can’t pass validation:

Configuration invalid!

Invalid config for [sensor.template]: invalid template (TemplateSyntaxError: expected token ':', got '}') for dictionary value @ data['sensors']['cheapest_custom_hours_energy_tomorrow']['value_template']. Got '{%- set numberOfSequentialHours = {{ states(\'input_number.sequential_hours\') | int }} -%} {%- set lastHour = 23 -%} {%- set firstHour = 0 -%}\n{%- if state_attr(\'sensor.nordpool_kwh_lt_eur_3_10_021\', \'tomorrow_valid\') == true -%}\n {%- set ns = namespace(counter=0, list=[], cheapestHour=today_at("00:00") + timedelta( hours = (24)), cheapestPrice=999.00) -%}\n {%- for i in range(firstHour + numberOfSequentialHours, lastHour2+1) -%}\n {%- set ns.counter = 0.0 -%}\n {%- for j in r.... (See ?, line ?).

Doesn’t work. Although it passes validation, sensor state is unavailable using this.

I just tried this in the template editor (using one of my input numbers). It works fine:

{%- set numberOfSequentialHours = states('input_number.rack_fan_dwell_time') | int(0) -%}
{{ numberOfSequentialHours }}

Many thanks, buddy. Got it working.
