The wiki article you link states 1) no direct evidence of a link or that their ideas were known beyond Kerala exists and 2) they might also have worked off ideas NY Islamic scholars. Really not sure what the specific claim or evidence you have is to give credit for 'many ideas' to this group.

Here's some evidence: "The Baudhāyana Sulba Sūtra states the rule referred to today in most of the world as the Pythagorean Theorem." "The Baudhāyana sūtras are a group of Vedic Sanskrit texts which cover dharma, daily ritual, mathematics, etc. They belong to the Taittiriya branch of the Krishna Yajurveda school and are among the earliest texts of the genre, perhaps compiled in the 8th to 6th centuries BCE." [1]

Note that the "perhaps compiled in the 8th to 6th centuries BCE", while still older than Pythagoras, comes from dating of Indian texts by European indologists. These indologists were funded by then-colonial governments in a then-colonized India with a view to advance the biblical worldview that the universe is about 6000 years old [2], which any reasonable thinker now knows is pure hogwash [3]. So Indian texts are, in fact, probably a lot older. I believe that a now-decolonized India needs to pay closer attention to its history.
