@ -64,3 +64,71 @@ Here we generate a bar graph of the battery level. We use the following steps to
"content": "{{ states('sensor.<device>_battery_level') }}%{% if is_state('binary_sensor.<device>_is_charging', 'on') %}+{% endif %} {{ '#' * (((states('sensor.<device>_battery_level') | int) / 100 * <width>) | int) }}{{ '_' * (<width> - (((states('sensor.<device>_battery_level') | int) / 100 * <width>) | int)) }}"

An example of a dimmer light with 4 brightness settings 0..3. Here our light worked on a percentage, so that had to be converted to the range 0..3.

## Warnings
Just remember, you have the ability to crash the application by creating an excessive menu definition. Older devices running as a widget can be limited in memory such that the JSON definition causes an "Out of Memory" error. Templates can require significant definition for highly customised text. Don't be silly.
