Customize - Sensor hidden dynamically, how?

Tomahawk · March 10, 2018, 7:24pm

I have two sensors. One sensor can get on of two values, “true” or “false”.

How to dynamically hide/display the other sensor in the GUI, set hidden: to true or false?

sensor.moon:
hidden: {{ states.sensor.moonphases_gui_hide.state }} -> Gives Config Error
hidden: “{{ states.sensor.moonphases_gui_hide.state }}” -> Does not work
hidden: ‘{{ states.sensor.moonphases_gui_hide.state }}’ -> Does not work

I am a bit baffled that Hassio only have code statement for hiding groups. What about other GUI items?

# Templates

The `templates` attributes allow you to inject your own expressions and code using JavaScript code or template literals in order to override entity attributes and state. Within the code / template literals, you have full access to the entity's state object, which allows you to access other properties such as last_changed, attributes.friendly_name, etc. The full set of objects available is shown below.

Additionally, `extra_data_template` attribute is always evaluated as a template without using `templates` attributes for it.

In order for a template to return "nothing", for example so that `extra_data_template` won't take space or allow showing `show_last_changed` - return `null` from your template. Note that `null` can only be returned using code format, as template literal format always returns a string.

**Note that those are JavaScript templates evaluated in your browser, not Jinja2 templates which are evaluated server-side and use a different syntax.**

### Available variables
#### Global variables
Those variables allow one entity to set state / attribute based on another entity or some other "external" thing. Using those hurts UI performance, so use them only if you indeed want an entity to depend on something external.

`hass` - the hass object

`entities` - a map object from `entity_id` to state objects.

#### Local Variables
`entity` - the state object for the current entity.

Customizer and/or customUI is the answer for dynamic front UI.
