Hello everyone,
I need your help. I am creating a new custom component and I want to translate the entities in it. I have read the documentation and I can’t understand why my entities are not translated.
Now I created a new custom component (example) just to try to understand this topic without having big complex function.
The example has two sensors and one binary sensor.
I have deleted and updated the browser cache. I just can’t get it to work.
Structure of this component:
en.json:
{
"title": "My Component",
"state": {
"motion": {
"on": "Motion detected",
"off": "No motion"
}
},
"entity": {
"sensor": {
"watt": {
"name": "Watt Sensor"
},
"volt": {
"name": "Volt Sensor"
}
},
"binary_sensor": {
"motion": {
"name": "Motion Sensor"
}
}
},
"service": {
"set_text": {
"name": "Set Text",
"description": "Set a custom text in the component.",
"field": {
"text": "The text to set."
}
}
}
}
de.json/strings.json:
{
"title": "Meine Komponente",
"state": {
"motion": {
"on": "Bewegung erkannt",
"off": "Keine Bewegung"
}
},
"entity": {
"sensor": {
"watt": {
"name": "Watt-Sensor"
},
"volt": {
"name": "Volt-Sensor"
}
},
"binary_sensor": {
"motion": {
"name": "Bewegungssensor"
}
}
},
"service": {
"set_text": {
"name": "Text setzen",
"description": "Einen benutzerdefinierten Text in der Komponente setzen.",
"field": {
"text": "Der zu setzende Text."
}
}
}
}

What have I overlooked/forgotten?
