Under the advanced settings for the UDM Pro, you can set the SSH Password. Ssh user is root.
On the network controller, settings, site, at the bottom it says device authentication.
Use root and the same password here for your switches and access points and then use that username and password in the plugin.
Your web password can be different.
In the plugin, where it says Controller Info and "use controller info" set it to off, since the controller api is different than device (including gateway) SSH and the api path (and perhaps some of the data returned) is different.
Hmm thanks, unless I am missing it then the UDM has different options to the UDM Pro. I'm not seeing any advanced options for the UDM
I do have the normal SSH device authentication options and have set them to root / password.
What version of software are you running, maybe there's a newer version for the Pro, it was certainly not a simple update process for the UDM, there were different versions all over the place?
My controller is 188.8.131.526
General is 5.12.42
