I am looking at reflashing a K800 to K810 with R8BF003. I have found

K810_R8BF003_MAIN_GENERIC_SM_RED53
K810_R8BF003_MAIN_GENERIC_WI_RED53
K810_R8BF003_FS_TELEF_GEN_RED53

My question is...what is the difference between SM and WI versions? What do SM and WI mean?

P.S. I know that I also need the K800 light effects.

Thanks
Darren
