I tried your example script with my informations, but received this error:

Using Python 3.8.2

Have you tried both encryption methods? (md5 and sha512). Could you try to log in via the router web interface, and run the following command via your console.

$.xmo.getValuesTree("Device/DeviceInfo")

[slimcdk]

Yea, I have tried both, which yields same error.

This is what I get from running that command.

Uncaught TypeError: Cannot read property 'getValuesTree' of undefined

Here are the full scripts and logs.

@slimcdk it looks like your FAST3890V2 model is using a different firmware than the others tested. I have the FAST3890V3 myself, which works like a charm. If you are not able to run $.xmo.getValuesTree("Device/DeviceInfo"), this means that they don't have the same internal API available unfortunately.

If you look in the Network tab of your console, do you see any XHR requests?

[slimcdk]

Yea, I guess you are right :/

There is no XHR type requests.
