+Currently, there are three methods to obtain the key:
 
 1. Via adopting a BLE shade: There is a [shade emulator](/emu/PV_BLE_cover) that works with Arduino IDE and an ESP32 device (≥ 2MiB flash, ≥ 128KiB required), e.g. [Adafruit QT Py ESP32-S3](https://www.adafruit.com/product/5426). Install and connect via serial port, then go to the PowerView app and add the shade `myPVcover` to your home. You will see a log message `set shade key: \xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx` . Copy this key. You can delete the shade from the app when done.
-2. Extracting from gateway: This [PR](https://github.com/patman15/hdpv_ble/pull/2) proposes a script to extract the key from a working PowerView gateway.
