You can also just grab the key out of the app data if you have root on an Android phone or an emulator. The emulator doesn’t even need to support bluetooth if you are logging in with an online account. I successfully extracted mine using Waydroid.
sqlite3 ~/.local/share/waydroid/data/data/com.hunterdouglas.powerview/databases/ExdadUesc0LMXnTCcTu4_7 'select home_key from homes;'
Not sure if the file name there is different for every user. On a real phone this would be at /data/data/com.hunterdouglas.powerview/databases/.
