The whole thing is a weird reverse of Gnosticism (material reality elevated as divine rather than immaterial reality) so it makes a little sense. 
Satanism developed after Mormonism did so I doubt there's really a connection there beyond detractors alleging there to be devil-worship going on in LDS temples. They're closer to a modern Gnostic sect than anything else.

I wonder how much credence these claims have. It is odd how similar the oaths and ordinances in Mormonism themselves match those Satan gives to Cain in BoM, especially swearing by the throat. The secret combinations of master Mahan.
