How to install Eufy Integration

Update: After poking around the file system I discovered I have python 3.8 NOT 3.9 installed, and there doesn’t seem to be ‘lakeside’ folder in 3.8.
Is there a simple and straight forward way to upgrade python to 3.9? I am a novice and not familiar how this interacts with Home Assistant OS.

Hi, I’m starting to learn HA to allow centralized control/monitoring of a few smart devices I have. I had HAOS 6.2 installed on a Rasperry PI 3+/. I want to add a couple Eufy plugs, and added the specified lines to my configuration.yaml, per the Eufy Integration page, but nothing is discovered. I get the following error in the log

Error while setting up eufy platform for switch

Thanks in advance for any guidance.
