Even templates for “command” do not work properly.

integration: command_line

### The problem Last year I opened an issue here and one day it was closed au…tomatically. Probably I should have monitored it once a week to prevent it become stale and closed. After almost a year a situation is *almost* the same. Details are below. Here is the old issue: https://github.com/home-assistant/core/issues/58847 ----------------------- Templates in `command-line` sensors do not work as they do in `template` sensors. *Case 1:* This does not contain templates and DOES WORK: ``` - platform: command_line name: "test command line2" command: "echo hello 123" scan_interval: 9999 ``` Output is: `hello 123` ------------------- *Case 2*: This contains templates and DOES WORK: ``` - platform: command_line name: "test command line" command: "echo hello {{ states('sun.sun') }}" scan_interval: 9999 ``` Output is: `hello below_horizon` ------------------- *Case 3*: This contains templates and *DOES NOT WORK*: ``` - platform: command_line name: "test command line3" command: >- {% if is_state("input_boolean.test_boolean","on") -%} {%- set KEY = "m" -%} {%- else -%} {%- set KEY = "h" -%} {%- endif -%} {{ "free -" + KEY }} scan_interval: 9999 ``` Output is: `unknown` Error in a log: ``` 2022-07-22 03:16:39 ERROR (SyncWorker_15) [homeassistant.components.command_line.sensor] Error rendering command template: TemplateSyntaxError: Encountered unknown tag 'else'.

Undrstood but that is a value_template, I am asking about an icon_template

Ildar_Gabdullin · October 13, 2022, 1:05pm

I mean - a basic templating for options is not working.
