APS Encryption

[prairiesnpr]

Is APS encryption required? I have a device that will not join if encryption is enabled, but when it is disabled by changing the hard coded options byte in the _handle_reply and request functions from 0x20 to 0x00 in application.py, it joins and functions perfectly. I haven't noticed any negative effects on the other ZigBee devices either. Just curious if there are any downsides I'm missing.

What is the device?
AFAIK all other libraries are using APS encryption, so it is on to maintain compatibility.

It's the same as this one: https://www.amazon.com/Aulley-Remote-Control-Switch-Compatible/dp/B07MM1TXDJ/

Not exactly something that's important to support. I just couldn't figure out why it would respond to commands sent via xctu, but HA would get transmit failures stating the address wasn't found. Traced it to the APS encryption flag, I currently have it off and all devices are working normally. Figured it had to be set for a reason though.
