Is it possible, wi-fi mesh 802.11s + wired RSTP

Hello, i'd like to know if it's possible to use mesh conection as a redundant way with wired conection. Actualy I have a successefull implemented openwrt mesh wireless conection, but, i want to know if its possible. Thank you very much.

Yes this is possible.
The upcoming v4.0.0 release of mesh11sd has this support built in. By default it works the other way round, using the mesh in preference to wired, but is a simple config parameter to do what you want.
Revised mesh11sd documentation is being written but if it is of interest I can post a link....
