In my understanding, the Tetragrammaton pentagram star is in reference to Yahweh/Jehovah?

Also in my understanding, Yahweh/Jehovah is not the same as the Heavenly Father.

Yahweh/Jehovah is a demiurge god and not to be confused with the Heavenly Father of Whom Jesus taught.

So, why do we revere this god Yod Hei Vav Hei as if it were the One true God when that isn't the case?

Any clarification would be much appreciated.
