If you don’t like the wording of a sensor output then the template sensor can help too. Processes monitored by the System Monitor sensor show on or off if they are running or not. This example shows how the output of a monitored glances process can be renamed.
sensor: + platform: template + sensors: + glances: + value_template: 'running' + friendly_name: 'Glances' +
This example shows a multiple line template with and if test. It looks at a sensing switch and shows on/off in the frontend. It disables warnings to avoid log messages where the switch it depends on isn’t loaded yet.
