ESPHome and Arduino Nano ESP32 integration

ESPHome

I’m trying to add an Arduino Nano ESP32 to HomeAssistant to be used as a climate controller.
I managed to add the Arduino Nano ESP32 to ESPHome Device Builder, but even if the Arduino is Online, it doesn’t show in the HA Devices section.
Some guidance and pointers in the form of examples or tutorial would be appreciated.
Thanks.

Have you added it to the ESPHome integration? Under Settings - Devices and Services - ESPHome

Thanks Daryl, it was so simple.
I thought the device would be automatically detected and added.
Adding it manually worked.
However, to upload the Arduino Nano ESP32 I had to place it under “firmware download mode” (the front LED is lit purple). Once the upload is finished, the LED remains lit purple.
Do you know if this is normal?

Try to press reset button or do a power cycle.

Thanks Karosm,
I already tried both with no success.
