Smartism worship all the major Hindu deities like Shiva, Vishnu, Shakti, Ganesha, Surya and Skanda. The Smarta tradition developed during the (early) Classical Period of Hinduism around the beginning of the Common Era, when Hinduism emerged from the interaction between Brahmanism and local traditions. The Smarta tradition is very much same as Advaita Vedanta, and consider Adi Shankara as its founder or reformer, who considered worship of God-with-attributes (saguna Brahman) as a journey towards ultimately realizing God-without-attributes (nirguna Brahman, Atman, Self-knowledge).
