[QUESTION] What is the latest software version for P110 that is compatible with PyP100?

[korsem]

Hi, I am currently using P110 plug with software version 1.3.0 with the new protocol.
I get the error Failed to initialize protocol AuthProtocol.
I've seen in readme that the new authentication method is currently compatible with the P100 version 1.2.1 and I am wondering if that is the latest version that is tested to be compatible?
Before the software update, the connection with my plug worked fine.
Do you have any suggestions to make it compatible with the 1.3.0 version? or maybe reason for my issue could be different?

I can confirm the current code base will read the P110 device. I ran through the basic functions, e.g. get device info, power stats and toggle on/off for firmware version 1.3.0 Build 230905 REL.152200

With a device on 1.3.1 Build 240621 Rel. 162048, I am not able to establish a connection. Also getting Failed to initialize protocol AuthProtocol, but the root cause seems to be that the failing connection itself:

requests.exceptions.ConnectionError: HTTPConnectionPool(host='<ip>', port=80): Max retries exceeded with url: /app (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f893b909b80>: Failed to establish a new connection: [Errno 113] No route to host'))
An error occurred during handshake: Failed to initialize protocol

It used to work in January. My network didn't really change since then, so I suspect it's at software level.

Could the firmware version be the cause for the device rejecting connections (compatibility issue or so...)?

As the Android app works fine, I wanted to test what accesses it makes (to compare it to what I try to do from the PC with python).

Short research results:

• according to PCAPdroid, Tapo app makes no local requests at all to the P110 plug - it connects to TP-Link's internet servers
• a cross-check confirms: when disabling internet access for Tapo app, the switch does not work and the energy infos are not shown in the app!

Can it be that since some version the local requests are not accepted anymore? Can anyone confirm that?

I have 3 devices, all with 1.3.1 Build 240621 Rel. 162048. And they still work fine.
