.. note::
|
|
|
|
|
|
|
|
|
|
The sensor has a 3-minute warmup period where data is unreliable and ESPHome will only start publishing sensor values after this time.
|
|
|
|
|
If the sensor was already powered only, such as if you restarted or updated your ESPHome device, then it will start publishing immediately.
