Using templates in script and modbus.write_register

Configuration
#1

Newbie problem
How to use templates in the following situation. Have this UI-generated script:
‘’’
modbustx:
alias: modbustx
sequence:

  • service: modbus.write_register
    data:
    address: 5
    unit: 1
    value: 200
    hub: hub1
    mode: queued
    max: 10
    ‘’’
    Wanted solution is to use a template something like
    ‘’’
    modbustx:
    description: “Send set point offset to temperature controller 1”
    sequence:>
    {% if (is_state(“input_boolean.ibstat1”, “on”) and is_state(“input_boolean.ibstat2”, “off”)) -%}
    • service: modbus.write_register
      data_template:
      address: 3
      unit: 1
      hub: hub1
      value: “{{ input_number.inboost }}”
      {%- endif %}

{% if (is_state(“input_boolean.ibstat1”, “on”) and is_state(“input_boolean.ibstat2”, “on”)) -%}

modbus.write_register

{%- endif %}

{% if (is_state(“input_boolean.ibstat1”, “off”) and is_state(“input_boolean.ibstat2”, “on”)) -%}

modbus.write_register

{%- endif %}

{% if (is_state(“input_boolean.ibstat1”, “off”) and is_state(“input_boolean.ibstat2”, “off”)) -%}

modbus.write_register

{%- endif %}

‘’’
Doable ?
I can’t figure out the right syntax

#2

You may have noticed that what you posted above is an illegible mess. Please review guideline 11 in the FAQ: Format it properly.

#3

Code snippets ARE between three back ticks as they should be.
For some reason I was surprised to see what the result looked like. The character I used is ‘’’ before the snippet begins and the same at the end. Seems that ’ character is somehow wrong.

#4

New try with proper back tics

What is the right syntax ?

Use an automation…

#6

You don’t need to use a template for that. Just add a condition to your script’s sequence.

There’s no need to create an automation. Automation actions are basically just scripts.

#7

Still fighting with this one. For a pro this must be a piece of cake.
Entity input_number.tupa_korotus is 9.0 at the moment and both booleans are ‘on’.
Have tried just about everything but still no go.
What’s wrong with this script snippet ?

BTW If the code doesn’t show as it should I’m writing this with the last version of Firefox.
I am sure the three Grave Accent characters are OK but still I get the warning of missing backticks.
Is there something I should know about FF when posting ?

alias: modbustx
variables:
  valuetosend: >
    {% if (is_state('input_boolean.ttupakotona', 'on') and is_state('input_boolean.ttupakorotus','on')) %} 
    '{{ input_number.tupa_korotus * 10 }}'  
    {% endif %}
sequence:
  - service: modbus.write_register
    data_template:
      address: 5
      unit: 1
      hub: hub1
      value: '{{ valuetosend | int }}'
mode: single

What’s wrong is the template for the valuetosend variable.

  • It contains a logic error. If neither of the two input_booleans is on it produces no value.
  • It contains a syntax error. If you want the value of an entity, like input_number.tupa_korotus, you should use the states() function to get it.

This version corrects the logic and syntax errors.

  valuetosend: >
    {% if (is_state('input_boolean.ttupakotona', 'on') and is_state('input_boolean.ttupakorotus','on')) %} 
      {{ states('input_number.tupa_korotus') | float(0) * 10 }}
    {% else %}
      0
    {% endif %}

In addition, if you use the int filter then you should provide it with a default value. For example: int(0) means if the filter is unable to convert the value to an integer, it will report 0.

#9

All 4 will be handled and they should create different values to valuetosend. I only used the first as an example.
Tried the suggested version but it always produces 0. So there must be something wrong with the sequence as well especially value: item.

#10

Sorryyyy there was a typo. It works now with the revised code. Thank you for your help and happy Xmas & New Year

Glad to hear it resolved the problem. Best wishes to you for the holidays.
