Failed to initialize protocol AuthProtocol

Thanks for solving the problem
Just a small add to your comments
Be carefull if you combine devices with the old protocol and the new one.

1. Add the preferred_protocol="old" at the inital statement of each old device
2. Don't delete the p100.handshake() and p100.login() for the devices that keep the old protocol

Hello,

1. Yes you need to add preferred_protocol="old" for all old devices individually
2. You should not need handshake() or login() , even for old devices. Please share the error if you still have an issue without it.

I still get this error even though I add the "old" argument.
MY code:

from PyP100 import PyP110
p110 = PyP110.P110("192.168.1.84", "xxx", "yyy",preferred_protocol="old" )
p110.getEnergyUsage()

Error:

Error: {'error_code': 1003}
