Local Sensor
Local Sensor is a Sensor card source for a sensor or text sensor running on the display device. It is read-only and continues to work while Home Assistant is unavailable.
Set Up a Local Sensor
- Define the sensor normally in the device's ESPHome YAML.
- Select a card, change its type to Sensor, then set Source to Local Sensor.
- Choose the sensor. The label and unit are filled in for you and can be changed.
- Choose Numeric for a value or Text for a live text state.
The picker normally shows your own sensors. Turn on Show internal sensors to include diagnostics such as Wi-Fi signal strength. If the setup page cannot reach the panel, enter the ESPHome sensor object_id as the Sensor Key.
The card updates at the sensor's normal ESPHome update rate. It shows -- until the first reading arrives.
For values already in Home Assistant, keep the standard Sensor source instead.
