You don't have to look far... https://community.octoprint.org/t/suppress-temperature-messages-not-working/20700/19 for background and additional details.
I think the regex in your case will be:
(Send: (N\d+\s+)?M105)|(Recv: TT::.*$)
Has latest Creality firmware fixed this issue? I upgraded to 1.1.2 (latest from Creality's web site) and Octoprint still reports the error.
If you are still getting the warning and seeing the temps reported as above, then no. I wouldn't hold out too much hope that it'll be fixed. The ideal solution would be to flash a non-buggy version of Marlin...
